Allan “Buddy” Rozansky, 79, who was a co-owner of several real estate development companies in the Washington area, died Jan. 8 at his home in Silver Spring.

He had cancer, said a daughter, Jaclynn Rozansky.

Allan Everett Rozansky was born in Washington and was a 1952 graduate of Coolidge High School. He attended the University of Maryland and served in the Army in the 1950s.

He formed a real estate company with Alan Kay, Kayro Realty, in the late 1950s. The two later operated Rozansky and Kay Construction Co. until 1986. Mr. Rozansky then founded Rozansky Development Co., which he operated for many years. His companies built residential and commercial buildings throughout the Washington region.

Mr. Rozansky also established a family trust that raised money for charitable groups, including Martha’s Table and the Yeshiva of Greater Washington. As a volunteer at the Hebrew Home of Greater Washington, he ran the Wednesday morning bingo game.

His marriages to the former Joann Wolman and Mary “Mimi” Dawson ended in divorce.
