Mount Sinai Hospital, formerly at times known as Mount Sinai Medical Center, is a 319-bed[citation needed] major urban hospital in Chicago, Illinois, with its main campus located adjacent to Douglass Park at 15th Street and California Avenue on the city's West Side. The hospital was established in 1912 under the name Maimonides Hospital, with a mission of serving poor immigrants from Europe while providing training to Jewish physicians, primarily of Eastern European descent. After a period of financial difficulty, it closed in 1918, and was reopened as "Mount Sinai Hospital" in 1919, with 60 beds and continuing its original mission.
