President George Albert Smith begins week's stay in California Lutheran Hospital for his "tired nerves," which his diary first refers to at Oct 1948 general conference. He is first LDS president with history of severe emotional illness and hospitalization. He does not recover from this episode until mid May 1949, when able to be in First Presidency office at least half day. Smith is absent from church headquarters 12 Jan to 27 Feb 1950 to stay at Laguna Beach, California, "to rest my nerves." He returns there to recuperate again for ten days in Mar. Year later his nurse notes that church president is "very confused, very nervous." Ten days before his death, nurse adds that George Albert Smith is "irrational at times."
