In early June 1947, Einstein made a final break with the foundation. The veterinary school was closed, despite students' protests and demonstrations. According to George Alpert, a lawyer responsible for much of the organizational effort, Einstein had wanted to offer the presidency of the school to left-wing scholar Harold Laski, someone that Alpert had characterized as "a man utterly alien to American principles of democracy, tarred with the Communist brush." He said, "I can compromise on any subject but one: that one is Americanism." Two of the foundation's trustees, S. Ralph Lazrus and Dr. Otto Nathan, quit the foundation at the same time as Einstein. In response, Alpert said that Lazrus and Nathan had tried to give Brandeis University a "radical, political orientation." Alpert also criticized Lazrus' lack of fundraising success and Nathan's failure to organize an educational advisory committee. Einstein said he, Lazrus, and Nathan "have always been and have always acted in complete harmony."
