In October 1902, Herzl met with the British colonial secretary,
Joseph Chamberlain, and England tentatively offered
El Arish in the
Sinai Peninsula for Jewish colonisation. This would lead, years later, to the
Balfour Declaration. During the negotiations, Herzl had Kessler in mind to participate in the expedition.
Oskar Marmorek, an
Austro-Hungarian Zionist, appealed to Kessler: "I know of no-one who could equal you and your knowledge for our expedition. It is therefore your duty, as a loyal comrade, to make the almost impossible, possible." Herzl received a document about El Arish from the British foreign secretary,
Henry Petty-Fitzmaurice, and noted in his diary that it suggested Marmorek, an
architect; Kessler, an engineer; and
Otto Warburg, an agricultural expert, for the expedition. Petty-Fitzmaurice wrote that in Kessler, he saw a "coolness and calmness" he admired, and that "because of his composure, I like Kessler very well as the leader" of the expedition. Herzl instructed Kessler to return with a report on the feasibility of settling El Arish. With that report, he hoped to obtain the charter. In a letter dated 28 January 1902 Herzl authorised Kessler’s leadership of the expedition and laid out his role and responsibilities. Other members of the expedition included
Selig Soskin, an agricultural expert, and
Hillel Yaffe, a physician to the Jewish colonies in Palestine. Kessler had become friendly with these men during his visit to Palestine in 1900. Also on the team were Marmorek;
Albert Goldsmid, a
colonel who had taken over Baron
Maurice de Hirsch’s Jewish colonies in
Argentina in 1892–93; Emile Laurent, a professor at the Agricultural Institute at
Gembloux; H. Stephens, an engineer, to investigate water problems; and a representative of the Egyptian government. Kessler himself was chief of the expedition, treasurer, and geological expert. The team toured the area from 11 February to 25 March 1903. The report signed by Kessler and the other members concluded that the project depended on water supply and, therefore, that the Egyptian government should give permission to divert some water from the
Nile. The Egyptian government, calculating that the plan would require five times the amount of water Stephens had estimated, turned down the proposal. Kessler, in a supplementary report, stressed that colonisation could be carried out without Nile waters (by damming
wadis, sinking wells, etc.), and Stephens reiterated his calculations with fresh evidence, but permission was once more refused. Kessler and Goldsmid then pursued futile political discussions with Egypt. == Uganda proposal ==
