Minna was never formally charged with espionage, survived the war, and would eventually return to Palestine to work for the medical service of the Zionist women's organization, Hadassah.
Pilot plant development of laboratory procedures was completed in 1915 at the J&W Nicholson & Co gin factory in Bow, London, so industrial scale production of acetone could begin in six British distilleries requisitioned for the purpose in early 1916.
The effort produced 30000 tonnes of acetone during the war, although a national collection of horse-chestnuts was required when supplies of maize were inadequate for the quantity of starch needed for fermentation.
At another conference on 21 February 1919 at Euston Hotel the peace envoy, Lord Bryce was reassured by the pledges against international terrorism, for currency regulation and fiscal controls.
As stated in his own words "I trust and feel sure in my heart that science will bring to this land both peace and a renewal of its youth, creating here the springs of a new spiritual and material life.
[37] His most recent biographers challenge this, describing him as a blatant elitist, disgusted by the masses, coldly aloof from his family, callous with friends if they did not support him, despondently alienated from Palestine, where he lived only with reluctance, and repelled by the Jewish immigrants from eastern Europe there.
[41] Scott described the diminutive leader asextraordinarily interesting, a rare combination of idealism and the severely practical which are the two essentials of statesmanship a perfectly clear sense conception of Jewish nationalism, an intense and burning sense of the Jew as Jew, just as strong, perhaps more so, as that of the German as German or the Englishman as Englishman, and secondly arising out of that and necessary for its satisfaction and development, his demand for a country, a home land which for him and for anyone during his view of Jewish nationality can be no other that the ancient home of his race.
[42]Scott wrote to the Liberal Party's Lloyd George who set up a meeting for a reluctant Weizmann with Herbert Samuel, President of the Local Government Board, who was now converted to Zionism.
[citation needed] Weizmann consulted several times with Samuel on the homeland policy during 1915, but H. H. Asquith, then Prime Minister, would be dead set against upsetting the balance of power on the Middle East.
Attitudes were changing to "dithyrambic"[clarification needed] opposition; but in the Cabinet, to the Samuel Memorandum, it remained implacably opposed with the exception of Chancellor Lloyd George.
Sokolow, Weizmann's diplomatic representative, cuttingly remarked to Picot underlining the irrelevance of the Triple Entente to French Jewry, but on 7 February 1917, the British government recognized the Zionist leader and agreed to expedite the claim.
"[47] The Manchester Zionists published a pamphlet Palestine on 26 January 1917, which did not reflect British policy, but already Sykes looked to Weizmann's leadership when they met on 20 March 1917.
"...those friends ... in close cooperation all these years", he suggested should become the EZF Council[49]- Manchester's Sieff, Sacher and Marks, and London's Leon Simon and Samuel Tolkowsky.
Just after the U.S. President, Woodrow Wilson, had left, the following morning, Lloyd George invited Weizmann to breakfast at which he promised Jewish support for Britain as the Jews "might be able to render more assistance than the Arabs.
[54] On 16 May 1917 the President of the Board of Deputies David Lindo Alexander QC co-signed a statement in the Times attacking Zionism and asserting that the Jewish Community in Britain was opposed to it.
[56] His Majesty's government view would favour the establishment in Palestine of a national home for the Jewish people, ...to use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country, 2 November 1917.A founder of so-called Synthetic Zionism, Weizmann supported grass-roots colonization efforts as well as high-level diplomatic activity.
[59] At the War Cabinet meeting of 4 October, chaired by Lloyd George and with Balfour present, Lord Curzon also opposed this "barren and desolate" place as a home for Jews.
[citation needed] On 2 December, Zionists celebrated the Declaration at the Opera House; the news of the Bolshevik Revolution, and withdrawal of Russian troops from the frontier war with Ottoman Empire, raised the pressure from Constantinople.
He believed that the Balfour Declaration and the legislation that followed it, such as the (3 June 1922) Churchill White Paper and the League of Nations Mandate for Palestine all represented an astonishing accomplishment for the Zionist movement.
[citation needed] On 3 January 1919, Weizmann met Hashemite Prince Faisal to sign the Faisal-Weizmann Agreement attempting to establish the legitimate existence of the state of Israel.
[66] At the end of the month, the Paris Peace Conference decided that the Arab provinces of the Ottoman Empire should be wholly separated and the newly conceived mandate-system applied to them.
At this time, simmering differences over competing European and American visions of Zionism, and its funding of development versus political activities, caused Weizmann to clash with Louis Brandeis.
[70] In 1921 Weizmann played an important role in supporting Pinhas Rutenberg's successful bid to the British for an exclusive electric concession for Palestine, in spite of bitter personal and principled disputes between the two figures.
[77] In 1936 and early 1937, Weizmann addressed the Peel Commission (set up by the returning Conservative Prime Minister Stanley Baldwin), whose job it was to consider the working of the British Mandate of Palestine.
[83] Weizmann made very clear in his autobiography that the failure of the international Zionist movement (between the wars) to encourage all Jews to act decisively and efficiently in great enough numbers to migrate to the Jerusalem area was the real cause for the call for a Partition deal.
Dr. H. Rosenblum, the editor of Haboker, a Tel Aviv daily that later became Yediot Aharonot, noted in late 1945 that Dr. Weizmann deeply resented the sudden intrusion and reception of Norman when he arrived in Britain.
Weizmann's efforts to integrate Jews from Palestine in the war against Germany resulted in the creation of the Jewish Brigade of the British Army which fought mainly in the Italian front.
[citation needed] In February 1943, the British government also rejected a plan to pay $3.5 million and just $50 per head to allow 70000, mostly Romanian, Jews to be protected and evacuated that Weizmann had suggested to the Americans.
In May 1944, the British detained Joel Brand, a Jewish activist from Budapest, who wanted to evacuate 1 million Jews from Hungary on 10000 trucks, with tea, coffee, cocoa, and soap.
In his presidential statement at the last Zionist congress that he attended at Basel on 9 December 1946 he said: "Massada, for all its heroism, was a disaster in our history; It is not our purpose or our right to plunge to destruction in order to bequeath a legend of martyrdom to posterity; Zionism was to mark the end of our glorious deaths and the beginning of a new path leading to life.
