The flagship Berkeley campus of the medical center was named after Alta Miner Bates, the nurse who founded the hospital in 1905. Bates was a prominent early California nurse anesthetist. The first graduate of a nurse training program in Eureka, California, she was among the first female anesthetists in the San Francisco Bay Area, administering over 14,000 anesthetics during her career. Until her retirement in 1949, Bates served as the hospital's director and was president of its board. Alta Bates Hospital, later renamed Alta Bates Medical Center until its merger with Summit Medical Center in 1999, is now known as the Alta Bates Campus of Alta Bates Summit Medical Center.
Herrick Campus
In 1904, Dr. LeRoy Francis Herrick, a graduate of the Kentucky College of Medicine, purchased a Berkeley mansion known as the Hume House, located on the same block upon which the current Herrick Campus is situated, between Dwight and Channing Ways, and Milvia and Grove. He converted the large home into a 25-bed hospital which he chose to name for President Theodore Roosevelt whom he admired. The Roosevelt Hospital was expanded to 50 beds by 1924, and renamed Berkeley General Hospital. In 1932, Dr. Herrick died, and his heirs converted the hospital into a non-profit corporation. By 1934, the hospital had 100 beds. The original Roosevelt Hospital building was demolished to accommodate additional wings and facilities which were added over time. In 1945, the hospital was again renamed Herrick Memorial Hospital, in honor of its founder. Further improvements and expansions continued through the ensuing decades. Herrick Memorial Hospital formally affiliated with Alta Bates Hospital in 1984 and fully merged in 1988. The joint organization, spanning both sites, was briefly named Alta Bates Herrick Hospital but became Alta Bates Medical Center in 1992. The site is now known as the Herrick Campus of Alta Bates Summit Medical Center.
Summit Campus
The Summit Campus of Alta Bates Summit Medical Center was previously three separately owned and operated facilities located in the same "Pill Hill" neighborhood, immediately north of downtown Oakland: Providence Hospital, Peralta Hospital and Samuel Merritt Hospital. Dr. Samuel Merritt was a successful San Francisco physician and also the 13th mayor of Oakland, California from 1867-69. In 1867, Merritt donated to the city of Oakland the wetlands now known as Lake Merritt. Merritt left plans for a hospital and nursing school to be built in his name after his death; in 1909 Samuel Merritt College and Merritt Hospital opened.
