Reichbach attended the University at Buffalo and studied political science during the tumultuous 1960s. He later studied law at Columbia University where he was active with the Students for a Democratic Society. After establishing a private legal practice, Reichbach was elected to the Civil Court of the City of New York and the Supreme Court of the State of New York. He also served as an International Judge for the United Nations Interim Administration Mission in Kosovo.
After his premature death from cancer in 2012, his wife, Ellen Meyers, donated Reichbach’s personal and professional papers to the University at Buffalo Archives.
The Gustin L. Reichbach Papers digital collection contains various items from the donated material.
