Einstein with Edwin Hubble in California (1931)
Einstein stayed in Pasadena, California as a visiting professor at Caltech for three winter terms, in 1931, ‘32 and ‘33. According to the Caltech Archive, he lived in a bungalow at 707 South Oakland Avenue in 1931 and in the “Einstein suite” of Caltech’s faculty club ‘The Athenaeum’ during the winters of 1932 and ‘33.

He first arrived via boat in San Diego on New Years Eve, 1930. His first appearance at an official Caltech event was a dinner on the 15th of January 1931. In attendence were over 200 members of the California Institute Associates, including cosmologist Richard Tolman (1881-1948), physicist Paul Epstein (1883-1966), “Martian” Theodore von Kármán (1881-1963) (read: The Martians of Budapest) and Nobel Laureate Albert A. Michelson (1852-1931), who would pass away only a few months later. Also there, pictured above, were his acquaintances Edwin P. Hubble (1889-1953) and Charles E. St. John (1857-1935). Hubble had just a few years prior confirmed the existence of cosmic expansion, a famous implication of Einstein’s field equations.
In the photograph above, Einstein can be seen with Milton L. Humason (1891-1972), Hubble, St. John, Michelson, William W. Campbell (1862-1938) and Walter S. Adams (1876-1956).
