Re: my post of 18 April mentioning the chemist who influenced the issuing of His Majesty's Government of "The Balfour Declaration". That was Chaim Weizman, who enabled the English to produce badly needed acetone in militarily significant quantities. Weizman went on to become the first President of the State Of Israel. His nephew, Ezer Weizman, a hero of the 1967 War and himself a past President of the State Of Israel, has just passed away.

His obituary which contains a lot of interesting information about Israeli history, appears in the New York Times here .
