Sheldon H. Solow, a Manhattan real estate developer who built a commercial and residential empire from scratch over a half-century, but left his son to finish his crowning project, a line of towers down the East River from the United Nations complex, died on Tuesday November 17 2020 in Manhattan. He was 92. His wife, Mia Fonssagrives Solow, confirmed the death, at Weill Cornell Medical Center, but did not specify a cause.

His father was a bricklayer who developed homes in Brooklyn but lost them during the Great Depression, forcing him to return to masonry work. Sheldon and his sisters, Renee and Rosalie, attended public schools in Brooklyn. After attending New York University for a year, he quit to try real estate. Mr. Solow married Ms. Fonssagrives, a sculptor and jewelry designer, in 1972. Besides his wife and his son Stefan, he is survived by another son, Nikolai Solow, and 13 grandchildren.
