Nine men representing various Jewish charitable organizations come together, to form what will become Mount Sinai Hospital in New York City, on January 15, 1852.

At this time other hospitals in New York City discriminate against Jews both by not hiring them, and by prohibiting them from being treated in the hospitals' wards.

Philanthropist Sampson Simson (1780–1857) founds the hospital to address the needs of New York City's rapidly growing Jewish immigrant community.

It is the second Jewish hospital in the United States, after the Jewish Hospital, located in Cincinnati, Ohio, which was established in 1847.

The Jews' Hospital in the City of New York, as it is initially called, is built on West 28th Street in Manhattan, between Seventh and Eighth Avenues, on land donated by Simson.

It opens two years before Simson's death.

Four years later, it will unexpectedly be filled to capacity with soldiers injured in the American Civil War.
