The story
Founded by Charles Groman, Hebrew Benevolent Society and Kaspare Cohn in 1902.1
Cedars of Lebanon Hospital
Kaspare Cohn Hospital was founded in 1902, named for its major donor, a Jewish businessman who later founded the bank that became Union Bank & Trust Company and is now part of U.S. Bancorp. The hospital's first superintendent, Sarah Vasen, was a graduate of the University of Iowa Medical School who had been the superintendent and obstetrician for the Jewish Maternity Home in Philadelphia. She was one of Los Angeles's first women doctors.
The hospital was intended to serve both the Jewish community and the patients of Jewish doctors, who were denied admitting privileges in other hospitals because of discrimination.
In 1930, the hospital moved to a new building in Hollywood and changed its name to Cedars of Lebanon Hospital, after the trees mentioned frequently in Scripture and reputed to have medicinal properties.
Mount Sinai Hospital
The Bikur Cholim Society, named for the Talmudic obligation to care for the sick, opened a hospice in 1923 that became Mount Sinai Home for the Incurables. It was renamed Mount Sinai Hospital in 1926 and moved to a 50-bed facility on Bonnie Beach Place in Los Angeles. In 1955, it moved to Beverly Boulevard, now the location of Cedars-Sinai.
Merger of Cedars of Lebanon Hospital and Mount Sinai Hospital
Discussions to merge Cedars of Lebanon and Mount Sinai began in the 1960s. Population growth in Los Angeles, along with the opportunity to expand free care, research and medical education required a larger patient base and expanded facilities.
The merger process, led by Irving Feintech and Steven Broidy Sr., led to groundbreaking in 1972 for a 1.6-million-square-foot medical center. It received its first patients in 1976. The new hospital was designed jointly by Albert C. Martin & Associates and Charles Luckman Associates. The main contractor was Robert E. McKee, Inc.
The merged hospital includes a full-time Jewish chaplain.
The Cedars-Sinai Health System was established in 1994, combining the Medical Center with the Burns and Allen Research Institute, the Cedars-Sinai Medical Foundation and the Physician-Hospital Organization. The Burns and Allen Research Institute is dedicated on George Burns' 100th birthday two years later in 1996.
