Moses M. Weinstein (July 8, 1912 – November 30, 2007 Pembroke Pines, Broward County, Florida) was an American lawyer and politician.
He was born Morris Weinstein without middle initial. A playbill for a production at Brooklyn College added erroneously the middle initial, and a mistaken inscription of his degree at Brooklyn Law School changed Morris to Moses which name he adopted henceforth.
He was born on July 8, 1912, in New York City, the son of a tailor, and grew up on the Lower East Side, Manhattan. He graduated from Thomas Jefferson High School at 15, but it took him seven years and a dozen jobs to work his way through college and law school.
In 1941, he married Muriel Marshall (d. 2006). They had three sons who all graduated from Brooklyn Law School too: Jeremy Weinstein, a New York Supreme Court justice and State Senator; Jonathan Weinstein; and Peter Weinstein, a Circuit Court judge in Broward County, Fla.
In World War II, he was an infantry corporal and fought in the Battle of the Bulge.
He was a member of the New York State Assembly from 1959 to 1969, sitting in the 172nd, 173rd, 174th, 175th, 176th, 177th and 178th New York State Legislatures. He was Majority Leader from 1965 to 1968, and as such became Acting Speaker for the remainder of the year upon the resignation of Speaker Anthony J. Travia after the close of the legislative session in 1968.
