To Chaim Weizmann [Haifa, 11 February 1923][1] Dear Mr. Weizmann, Yesterday and today I visited the technical high school and the technical college in Haifa[2] and got a very favorable impression of the educational work up to now. It would be of great benefit if the means could be found to get the teaching started at the technical college, because everything is ready and the need is great. The problems here are great but the mood is positive and the work admirable. Cordial regards and good success, yours, Einstein. 430. To Arthur S.
