Louis Bamberger (15 May 1855 – 11 March 1944) was a citizen of Newark, New Jersey, from the early 1900s until his death in 1944.

[1][2] He and his sister Caroline Bamberger Fuld co-founded the Institute for Advanced Study in Princeton, New Jersey.

[3] He came to Newark in 1892 and bought at auction a failing general goods store on Market Street, renaming it L. Bamberger & Company,[1][2] with his partners, brothers-in-law Felix Fuld and Louis M.

[4][2] The store was an immediate success, and Bamberger was able to open an ornate chateauesque building in 1912 that covered a whole city block.

[5] Bamberger was also a major contributor to the Community Chest and Beth Israel Hospital.
