On January 15, 1852, nine men representing various Hebrew charitable organizations came together to establish the Jews' Hospital in New York with a vision of offering free medical care to the indigent Hebrews in the City who were unable to provide for themselves during their illness. This was the beginning of The Mount Sinai Hospital. Now, a century and a half later, "This House of Noble Deeds" celebrates the scientific and medical achievements of The Mount Sinai Hospital. From its original 45-bed building, the Mount Sinai Medical Center has developed into a state-of-the-art facility comprising a 1200-bed hospital, a major medical school, and a research enterprise with a faculty of almost 3000. Arthur H. Aufses, Jr. and Barbara J. Niss have identified and documented the most important scientific contributions of Mount Sinai over the past 150 years. They present histories of each major department and division, rich with anecdotes, biographical sketches, and photographs. In addition, they share the fascinating story of the hospital's creation and development, a story that ultimately transcends the parameters of the hospital itself and speaks to the broader matter of Jewish and medical history in New York.
