Josiah Greenberg ’81 was a founding partner at the firm of Greenberg & Oser in Montclair, N.J., and the son of renowned civil rights attorney and Columbia Law School Professor Jack Greenberg ’48 O. He passed away on January 5, 2011, at the age of 58.
A graduate of Great Neck South High School in Great Neck, N.Y., Greenberg attended Columbia College and the Law School, where he became a Harlan Fiske Stone Scholar. Following his graduation in 1981, Greenberg clerked for Judge U.W. Clemon of the U.S. District Court for the Northern District of Alabama before joining the New York City office of Weil Gotshal & Manges as an associate specializing in antitrust law.
After two years at Weil, Greenberg accepted a position at Stecher Jaglom & Prutzman, a small general practice firm in Manhattan, where he eventually rose to partner. Then, in 2005, Greenberg co-founded Greenberg & Oser in Montclair, N.J.
Throughout his career, Greenberg remained an active member of his community. In 2009, he helped collect signatures on a petition that called for members of the town’s education board to be elected, rather than appointed.
Greenberg also lobbied to increase the number of languages taught in area schools. “[He] had great persistence and discipline in how he approached all matters, large and small,” recalled his colleague Roy Oser in an article in The Montclair Times. “He was an absolute standup, straight-shooting person.”
Greenberg is survived by his wife, Janette, and his daughters, Jessica and Julia, as well as his parents, brothers, and sisters.
