Albert Einstein visited Palestine in 1923 for 12 days, giving the first lecture at the Mount Scopus campus of the Hebrew University of Jerusalem—two years before the university opened in 1925. Menachem Ussishkin, the president of the Zionist Executive, invited Einstein to settle in Jerusalem, but this was the only visit that Einstein actually made to Jerusalem. However, Einstein was a member of the university's first board of governors. In 1925, the original 46-page manuscript of the general theory of relativity ended up at the Hebrew University of Jerusalem.
