David Lubin (1849-1919)
An Appreciation
In the first hours of
1919 one of the great originators of cooperation between countries for the
benefit of all men died in Rome. David
Lubin was not only an original thinker about world agricultural problems but
also a man of action who left behind him a successful accomplishment - the
International Institute of Agriculture, established in 1905.
The Food and
Agriculture Organization which has superseded David Lubin's Institute has a
programme which is much broader than that of the older organization. Yet the difference between the two
organizations is more one of scale than of fundamental intent. Central to the programmes of both is concern
for the farmer and for agriculture as the basis for overall economic development.
In June 1969, the 52nd
session of FAO's 34-nation council, during its discussions of the future of
world agriculture, took time out to commemorate the life and work of a man
whose ideas and ideals are as relevant today as they were when he died half a
century ago. The statements made are reproduced in the following pages.
The Chairman: We have with us
members of Mr. Lubin's family Mrs. Evangelina Lubin-Silenze, Mr. David Lubin's
daughter, accompanied by several other members of the family. I welcome them on behalf of the Council and
say to them how much we appreciate their presence on this day when we
commemorate the death of an eminent man who took part in the creation of this
house.
I now give the floor to
personages who are more familiar than I am with the origin of our Organization.
Mr. Cépède (France): Mr.
Chairman, Mr. Director-General, Madam, my dear Colleagues, Ladies and
Gentlemen.
Among the great dead whose work
we aspire to continue in this Organization, the earliest was David Lubin who
died in Rome on 1 January 1919.
Within four days he was carried
off by the influenza epidemic which ravaged Europe following the First World
War, claiming more victims than the conflict itself.
The founder of the
International Institute of Agriculture was born at Klodowa near Cracow on 1
June 1849 - June 13 according to the Western calendar - the youngest of six
children whose father died of cholera shortly afterwards.
His mother, remarried to
Solomon Weinstock, decided to emigrate to the United States. After spending two years in London, where his
half-brother Harris was born in 1854, they arrived in New York in 1855. David was about six years old. At 12 he left school to earn a living.
He went to work in
Massachusetts where his elder brother Simon was a goldsmith and jeweller. In this craft he worked as a solderer and
polisher for about four years at North Attleboro with Morse Brothers.
In 1865, his sister Jeannette,
married in California, called him to San Francisco where he worked as a jeweler
for some months, but then took a job in a timber yard at Los Angeles.
In 1868, he set out for Arizona
in a group of 14 prospectors. He found
neither gold nor oil...
On 8 October 1871, on his way
back to New York, he lost everything except his clothes and violin, in the
Great Fire of Chicago.
He then worked as a traveling
salesman for a lamp factory... inventing a non-explosive oil lamp.
After a first trip to Europe,
which took him from Amsterdam to Poland, he and his half-brother Harris
Weinstock rejoined their widowed sister Jeannette in 1974. They worked together in a clothing shop. Then, after accumulating a capital of 600
dollars, they opened a new type shop, “D. Lubin One Price”, at 100 K Street,
Sacramento, on 6 October 1874.
Ten years later, D. Lubin
headed the biggest department store and mail order house on the Pacific
coast... He was able to fulfill the
promise that one day, when he had enough money, he would take his mother to the
Holy Land.
They crossed the United States,
England France and Italy, visiting museums, then Egypt whence they reached
Jaffa.
He had very little or nothing
of what Europeans call “culture”. His
aesthetic sense was rudimentary. He
could perceive and appreciate the beauty of sanctity, but not the sanctity of
beauty.
Nothing in David Lubin’s
adventurous life up to that moment was very different from the lives of
pioneers who had made a fortune in the conquest of the West... Nothing foreshadowed the prophet of a new
order and of a peace made more secure by justice for farmers, announced at the
International Agriculture Congress in 1896...
the author of “let there be light” in 1900... the founder of the
International Institute of Agriculture in 1905... the champion of the “United
States of the World” who in 1911 proposed the establishment of a “Permanent
International Parliament” to ensure peace among nations by economic
progress... the author, publisher and
disseminator in 1917 of “An International Confederation of Democracies under a
Constitution” in one and half million copies in English but also in Chinese,
French and Italian...
Yet David Lubin’s life, which
we can recall here only in broad outline, is worthy of the great heroes of
mankind.
What a fine edifying story -
why not in cartoon strips - we could tell our children and children’s children!
What a new chapter an inspired pen could write about it...
... For it has all the
ingredients of the beautiful legends of predestined men: There is that mark on the face caused by the
burn when a Sabbath candle fell into his cradle on the fourth day of his
life...
... the wrath of the saintly
man whom the father has brought to share the evening meal and who scolds the
mother for weeping over her son injured on such a day, and who praises the Lord
for choosing by this sign this infant for His service...
“You wanted to call him
Pinchas, like his grandfather. You are
going to call him DAVID because he will grow up to be a mighty man among his
own people; he will sit at the table of
kings!...
There is this pious mother who
“keeps all this in her heart”... There
is that two years’disappearance in the Arizona desert where death grazed him
several times...
There is this extraordinary
material success of a man who refuses to swerve from the “straight path” of
those “who demand and who give full weight and full measure”...
His watchword is
“RIGHTEOUSNESS”: Rectitude but also
Justice, the cry of all the revolts of the oppressed.
This man who used to say that
life in a ghetto of Czarist Russia was less dangerous for men than the
conditions which elsewhere reduce them to the materialism of worshippers of
MAMMON, considered himself a “fighter for God”:
“Fighter for God” for the same reason as “that band of faithful workers
of all times and of all nations who have striven for development and
civilization”, as he said in Washington in November of 1911.
David Lubin realized the
greatness of his mission but he regarded himself only as an ordinary man. He explained his stand in a letter of
September 1908 to Gilford Pinchot, founder of the American Forestry Service:
“I think that you follow
me. But humanlike you want to know my
motive before you can trust me. Well, my
motive is not salary, not medal, nor social scintillations, nor is it to be a
Count of Sacramento. I wish to serve the
dear old Uncle, Uncle Samuel, and you laugh!
But how many better men have given their lives for the Uncle. But there is a higher service still, and that
is for the United States of the World.
And I am happy to be a humble soldier, a private, in this Army. Do you understand? And when one is such in dead earnest, the
Almighty does not mind that he is an ordinary scrub and no educated diplomat.
“The same Almighty makes him a
persona gratissima just everywhere, because this is His great fun in His Divine
Comedy. And that is the reason that He
took common scrubs for His prophets and His great workers, and ‘who shall say
Him nay?’...”
The superb impertinence David
Lubin derived from these convictions enabled him to succeed in business
although he went against the stream on what appeared to be the way to
success; it was going to enable him to
win his struggle for Justice among nations, as he had won the struggle for
Justice among individuals.
This is what matters for us
here and what has now to be recalled.
First of all, how did David Lubin become involved in AGRICULTURE?
The explanation must doubtless
be sought in the long frustration of a family debarred for centuries from the
possession of land, who descendant, after reaching a free country, realized
that the crowning of his economic success would be incomplete without the
ownership of a farm holding.
Thus, on his return to
California in 1885, he began to grow wheat on two areas of Colusa County and to
cultivate 120 hectares of orchard about 10 to 15 miles from Sacramento. He used modern techniques, such as
agricultural explosives which Frenchmen had taught him.
But technique was not enough,
for 1885 was the first year in California when supply exceeded demand... when
the best peaches, apricots and table grapes were sold at prices that did not
even cover their packing.
People were talking about
“overproduction”, about uprooting orchards and vineyards and seeking their luck
elsewhere.
David Lubin, who had suffered
heavy losses, told the Fruit Growers’convention of San Francisco as early as
September 1885 that it was absurd to talk of overproduction, that supply was a
mere trifle compared with the demand of those who wished to eat good fruit if
they could pay for it.
He organized the California
Fruit Growers’ Exchange. The following
year - 1886 - was another very bad year.
David cabled from London to recommend sale by auction, as at Covent
Garden.
In 1893, wheat was in a crisis.
David Lubin realized that it
was not merely a Californian problem and extended his action to the United
States as a whole.
In 1894, he launched the direct
sale of farm produce by mail, then pressed for import duties on industrial
products and export premiums for farm produce.
The farmers’ lot had to be improved by raising prices “faked” to the
detriment of producers.
In the spring of 1896, the
crisis had exhausted David Lubin; his
home was shattered and he left for Europe with his five children and their
governess.
The Californian who had become
an American was going to become a citizen of the world in 1896.
On the occasion of the
millennium of Hungary, Budapest had been chosen as the venue of the
International Agriculture Congress. No
American was listed as a participant, and the Hungarian Agriculture Minister
invited David Lubin who explained to the congress what later became his project
for an International Agriculture Organization.
On his return to the United States
in December, he settled in Philadelphia, remarried in 1897, and opened a San
Francisco branch of the Sacramento department store - “Weinstock Lubin and Co”.
In August of 1904, he left New
York to lay his project before the European governments.
Received with scepticism more or less
everywhere, David Lubin decided to go to Italy and deal with King Victor
Emmanuel III himself. He reached Rome on
4 October 1904.
He asked Commendatore Chimoni,
Director-General of Agriculture, straight out, how he could meet the king.
“There are names that must not
be lightly invoked” he was told... But David Lubin was not so easily put off
and insisted... To get rid of the
nuisance, he was told that the king had left Rome, that he was in his hunting
reserve at San Rossore near Pisa.
That was no obstacle for
Lubin. He travelled to Pisa and asked
for an audience. At 9 p.m. on Saturday,
22 October, he received a summons for 9 a.m. on Sunday, the 23rd!
Lubin had no time to buy what
he had been told was indispensable for the audience - hat, gloves... Never mind.
He set out for San Rossore at dawn and arrived long before the appointed
time... The audience, scheduled for ten
minutes, lasted three-quarters of an hour!
Victor Emmanuel, taken aback at
first, decided to listen to this America citizen who was talking with the
impertinence of a man of God coming from the desert... In fact, David Lubin’s speech was not of the
kind a sovereign normally hears: “I
bring you the opportunity to perform a work of historic importance, which will
entitle you to more enduring fame than the Caesars; they earned fame by wars, you would earn it
by working for peace, the peace of righteousness... You are, of course, a very important person
here, but remember you are a small potato in the world, the monarch of a
third-rate nation. Take up this work in
earnest and at one leap Italy can head the nations in the general fight of our
days: the fight for Justice in economic
relations.”
Victor Emmanuel III agreed to
sponsor the project: when it had been
worked out, he would submit it to the Italian Government.
Lubin returned to Rome and on
the evening of October 25, at the Bristol Hotel, assembled a group of Italian
friends - Pantaleoni, Montemartini, Guerazzi, Agresti, Bosco, Colletti - for
the first working session... Many others
followed.
And on 24 January 1905 Victor
Emmanuel III wrote the famous letter to his Prime Minister:
“My dear President,
“A citizen of the United States
of America, Mr. David Lubin, has explained to me, with all the warmth springing
from sincere conviction, what appears to me a happy and good idea and I commend
it to the attention of my Government.
“The rural classes are generally the most numerous and have great
influence on the conditions of nations everywhere but, scattered as they are,
they cannot do what would be necessary to improve the various crops and
distribute them in line with the requirements of consumption. Moreover, they cannot adequately defend their
interests on the market which, for the most important produce of the soil, is
widening more and more to embrace the whole world.
“Therefore, it might be
extremely useful to set up an International Institute which, without any
political designs, would study the conditions of agriculture in the various
countries of the world and would periodically issue information on the quantity
and quality of crops...” Here I stop my quotation.
An international conference was
called in Rome. It opened on 28 May 1905
and resulted in the signature of the Convention of 7 June 1905 by 40 states -
38 years before Hot Springs... For David
Lubin, this success was to be accompanied by many disappointments and
difficulties.
Obtaining a hearing from a
sovereign who had no other reason to receive you than the title of “citizen of
the United States of America”... and convincing him by “warmth springing from
sincere conviction”... was by no means impossible for someone who wished to be
a “fighter for God”, but the fight David Lubin had to wage with the
governments, or rather the bureaucracies, of the member states of the
conference, and later of the Institute, was altogether of a different nature!
People distrusted “David
Lubin’s ideal and somewhat nebulous concepts” and the “generous and humanitarian
ideas contained in the letter of His Majesty the King of Italy”. This had to be turned into “practical
action”. I have taken these terms from
Louis Dop who was for a long time the French delegate and vice-president of the
Institute... This is how he set out “the
very vast and very complex idea, but very imprecise and very vague as to its
means of implementation”, before the Academy of Agriculture in Paris 20 years
later:
“David Lubin’s great idea
consisted above all in setting up an international commercial organization of
agriculture. For David Lubin, farmers
suffer especially from their isolation and their powerlessness to fight against
organizations which, as industrial or commercial trusts and cartels, impose on
them their tariffs, prices, their economic and financial conditions, which
keeps agricultural production in a constant state of inferiority compared with
industrial production.”
To fight against this
irresistible force of companies and trusts, David Lubin said, it was necessary to
oppose it with an equal or superior force.
This force was to have as its principles the collective interest, as its
rule the use of licit means in conformity with established laws, and as its aim
the satisfaction of farmers’ individual and collective efforts to provide the
producer with a reasonable and legitimate benefit. This force was to be backed by state
aid. No, David Lubin’s ideas were not
“vague”. The less they were, the less
they were acceptable to many people. The
Conference was going to show it soon:
David Lubin envisaged the
Institute as composed of two chambers:
An upper house in which each
country was represented by one member, and a lower house consisting of members
elected by private agricultural organizations on the basis of their membership
and importance.
The Institute was an
exclusively intergovernmental body in which the states could, at their request,
have one to five votes, depending on their commitment to pay for 1 to 16
shares; the colonies, at the request of
the countries on which they depended, could be admitted to the Institute on the
same conditions as the independent states...
David Lubin had originally thought that the Institute should have an
“International Trade Commission” with powers similar to those of the U.S.
Federal Trade Commission. The Institute
was given only tasks of study, documentation and information... Yet David Lubin never gave up his plan. In 1917, he wrote in “An International
Confederation of Democracies under a Constitution”:
“The International Institute of
Agriculture and the International Postal Union are already here to serve the
purposes of the Confederation, perhaps with added powers and increased
duties. Similarly departments could be
formed to deal with the international phases of commerce and labor when
reciprocal commercial and industrial treaty measures could be placed in their
hands, while the Department of Transports could be entrusted with the
international phases of Ocean carriage”.
Then, from the 1905 Conference,
the battle of the budget was joined: 850 000 gold francs a year, of which 300
000 lire was provided by the annual contribution of His Majesty the King of
Italy, was considered necessary. The
quotas to be subscribed by the member states were thus limited to 550 000
francs for 40 countries, some of which paid for up to 16 units. It was not ruinous.
Nevertheless other precautions
were taken: a unit must never exceed 2 500 francs, and 1 500 francs in the
transition period of the first two years...
The General Assembly and the
Permanent Committee were assisted by a Secretariat headed by a
Secretary-General, which comprised three offices - statistics, agricultural
information, as well as economic and social studies - and two services -
legislation and library.
This Secretariat started
operations in 1908.
In the following year David
Lubin reprimanded the officers of the Institute who asked for time to make
studies and... suggested that commissions be set up.
“While you are studying, the
governments will get tired of paying, and the Institute will die of inanition.”
In spite of its limited tasks
and its modest resources, the Institute’s possible action gave rise to concern:
Professionals of international
trade did not like the simple dissemination of information. Louis Dop presented to David Lubin the
magnate of the wheat trade, Louis Dreyfus, who tried to argue the case for long
studies - ten years, it seemed to him, were the minimum: “Remember that the
world’s eyes are on the Institute and you must do nothing, give no advice and
no information before you are absolutely certain about it”. If he had been more cynical, he might have
added the tenet of that agent of the Union Stockyard in Chicago who complained
that the Bureau of Agricultural Economics of the US Department of Agriculture
was issuing too much information: “A piece of information known to everybody is
of no interest to me, but a piece of information that I have and the others
have not can be turned into money! ..”. s
This conversation could not but strengthen David Lubin’s determination
to urge the Institute to go ahead because this was proof that the farmers’
isolation and their lack of information were the cause of their exploitation by
industrial and trading companies, trusts and cartels.
The idea of stabilizing prices
at an equitable level for producers, and therefore of raising them, also caused
the governments of importing countries to prick up their ears.
David Lubin had to go and
explain his faith that justice was in the common interest. In 1906, for example, he told the Board of
Trade:
“I can see what’s in your
minds, Gentlemen. You think that England
is a buyer not a grower of the staples, and you fear that the activities of the
Institute would tend to level up prices, making it increasingly difficult to
secure ‘deals’ in the less organized countries, such as Argentina or Russia or
the Balkans.
“The cheap loaf is good for the
British workman and may not the Institute interfere with the cheap loaf? Now the cheap loaf may be all very well, but
there is another side of the story. You
have some industries in England, you sell your manufactures abroad: Your cotton
stuffs, your machinery, your boots, your valises, your suspenders and what not
- and you export capital.
“England holds bonds and stocks
and shares in those very countries. Now
if you squeeze the life out of them, if you force down the price of their
staples through price manipulation, it may seem a cheap loaf and a big stomach
for the British workman today but, mind you, it may mean unemployment for him
tomorrow.
“That same workman will soon
find his job gone, for such a policy amounts to strangling your best markets;
your bonds and shares will not be worth the paper they are printed on. You will kill the goose that lays the golden
egg. Help to build the Institute up and
make it a living force working for equity in exchange and you will be building
up the economic strength, the purchasing power of the great agricultural
countries which are the natural market for British manufactures”.
Until his death David Lubin
fought to strengthen the Institute, and his struggle proves that the weaknesses
of this first organization were not due to the “vague” ideas of its promoter
but to the brakes put on its action by selfish private or national interests...
However, David Lubin had the
great joy of seeing his work live through the First World War, preserved as it
was from political debates. In 1915, all
the belligerents worked side by side on the best methods for drawing up the
half-yearly grain balance-sheets... This miracle was repeated at the 15th
General Assembly in May of 1940, when all the belligerents of the time were
represented among the 38 delegations present... Later, when nothing could be
expected of governments, and at worse moments, the Institute was nevertheless
kept up as a place of asylum... This, too, would have shown David Lubin that
his spirit had survived in his work.
For despite the difficulties
our Organization and younger ones encountered and are encountering, David Lubin was able to
accomplish an undertaking which, as he predicted to Victor Emmanuel III, has
given pure glory to this sovereign and an historic place to Italy in the
struggle for justice in economic relations.
While his native land and his
people, as well as California and the United States of America may be proud of
David Lubin... this “fighter for God”, this “citizen of the world”, “just an
ordinary scrub man”, belongs to all of us...
He has deserved well of
mankind.
The Chairman: I thank you,
Professor Cépède, in the name of the entire audience, for your moving
speech on the origins of this house. I
am now, with the permission of the Council, going to ask Professor Papi to take
the floor.
Professor Papi (Italy): Mr.
Chairman, Distinguished Delegates, Mrs. Silenze, Your Excellencies, Ladies and
Gentlemen, the Italian Delegation is very much appreciative of the celebration
of the anniversary of David Lubin at the beginning of the work of this Council
Session. It has listened with interest
and admiration to the effective speech of Mr. Cépède. I would like to thank the French Delegate for
having recalled with delicate taste some episodes and characteristics of the founder
of the International Institute of Agriculture and of his environment.
Now, at a distance of many
decades, the size of an unusual personality can only be measured by the power
and by the lasting fertility of his invention.
David Lubin was indeed a pioneer in the field of collaboration among countries
for a better international community.
His faith in the method of diffusing confidence in a concerted action
among governments has been largely supported by the examples the more numerous
international organizations, created later on, have continuously offered.
But the merits of David Lubin
cannot be confined to the creation of the International Institute of
Agriculture, the first among international organizations. His merits have made a much greater impact,
in my very modest opinion. He spread the
notion of the immense usefulness of political and technical cooperation all
over the world, and we are now already experiencing some considerable and
fruitful results.
David Lubin started using a
juridical instrument: the convention. By
convention, on 7 June 1905, as has been recalled by Mr. Cépède, was
established the International Institute of Agriculture. In its turn, the Institute, by means of six
conventions, promoted the solution of various technical matters. For the first time it was possible to present
an alternative to incomprehension and misunderstanding. For the first time it was possible to replace ignorance and the
blind struggle of immediate interests with the order and rectitude of
international law.
Should every government, being
aware of its responsibility, decide, in agreement with other governments, to
enact assiduous confrontation of its own economic policy with the policies of
other governments, as the experience largely demonstrates, each government
would more easily attain an equilibrium also in its national behavior between
its own structure policy and price stabilization policy.
What, in the spirit of David
Lubin, does FAO actually do after sixty years of trial and error in
international cooperation? FAO carries
out surveys, undertakes studies, converts its action into “conventions”. By conventions, for example, FAO upon request
by a country, grants technical assistance.
By conventions, FAO on several occasions, has sent equipment to the
less-advanced countries.
But at the same time - and this is the
fruitful result of the work of David Lubin - the assiduous work for the
preparation of recommendations and of concerted action imply another major
activity which FAO is performing in the same spirit of cooperation, diffused by David Lubin, with invitations
sent to Member Governments and other International Organizations to participate
in its conferences, Council sessions, meetings of commissions, committees and
working groups. FAO leads the
administrations of the various countries to take a new look at the problems
facing their respective governments.
We see so frequently within
these walls young Ministers representing countries which have acquired
political independence only recently, through strong drives of chauvinism
coming to listen to appeasing and solemn declarations during the sessions of
the Organization. The young Ministers,
the young functionaries are induced to consider the matters according to a
technique which they could hardly find in any literature, and this is, in my
very modest opinion, a result of enormous importance because the countries they
represent are precisely the countries which need FAO most, and which need FAO
much more than, for instance, other countries like the United States, Russia and
the United Kingdom.
The faith in the method of
mutual understanding and cooperation instilled by David Lubin will never, I
hope, disappear. More particularly, now
it has to inspire the translation into practice of the tremendous task of
helping the developing countries. What
does, for instance, the Indicative World Plan - in preparation by the FAO
Secretariat - also mean if not the utmost expression of collaboration among
governments by the intermediation of an international organization like ours. The three stages of the Indicative World
Plan: Projections for agricultural
commodities in 1975 and 1985; regional
and sub-regional studies, embodying suggestions about the policy structure best
suited to each region; and assistance by
FAO to the representatives of the countries concerned, at their request, to
draw up a development project, country by country, in each region - all these
stages imply the highest degree of world cooperation, so that we can nowadays
see in full operation the spirit which has inspired the pioneer work of David
Lubin, a spirit continuously present and continuously expanding, the more
technological progress is developing.
May I submit that exactly this
spirit of mutual comprehension and assistance which animated the first realization
by David Lubin and gave origin to the many other international bodies, makes
his stature at so great a distance in time, really a gigantic one. The aspirations, the ideals of David Lubin
are becoming universal, are enhancing international collaboration, are
permitting us to pursue not only practical results but much nobler
purposes. For instance: to free man from want and to create more and
more free men. Only a man who is free
can really be the promoter of his own economic and social progress. Only a man who is free can really be
beneficial to mankind, and this is the unforgettable teaching left by David
Lubin.
The Chairman: the Council will allow me, no doubt, to thank
Professor Papi for his stirring speech.
A.J. Mair (United States of
America): The United States Delegation
is deeply appreciative of the statement just made by Mr. Cépède, the
Delegate of France, and the eloquent words of Professor Papi. David Lubin was not only a highly respected
citizen of our country but, in a very real sense, he was a citizen of the
world. At a time when serious thinking
regarding cooperation among countries through international organizations had
hardly begun to emerge, David Lubin had the foresight not only to see the
problems of the farmers of his own country, but to recognize that these
problems were linked to the problems of the farmers around the world. He had the vision and the fortitude to set
out to do something about it, to create some kind of international mechanism,
through which the combined forces of farmers everywhere could be heard. He was thus a pioneer in the field which
evolved very slowly over the 40-odd years that elapsed after his frustrating
efforts led him to Rome and to some degree of success.
That initial effort by David
Lubin opened the way to a substantial expansion in international activities
following World War II, and FAO is one of the major results of that expansion.
Consequently we are grateful
for the recognition given today by this Council to the contributions of David
Lubin to international cooperation in the field of agriculture.
While I have the floor, I also
wish to express my personal appreciation of the welcome we have received here
today. Thank you very much.
The Chairman: After these speeches, that were so eloquent
and stirring, I believe, and you will certainly agree also, that we should not
prolong our meeting, so that we may keep in our minds the memory of the moving
words of the speakers.
The meeting rose at 12.35
hours.
