Mr. Lindenbaum’s practice focuses primarily on zoning and land use matters. With almost fifty years of experience, Mr. Lindenbaum has handled a wide range of legal matters related to real estate and land use, including special permits, zoning changes, variances, landmark proceedings, air rights transfers, tax abatements and economic development incentives for many of the city’s most prominent commercial and residential developments and for the expansion programs of many of the city’s leading non-profit institutions. Samuel Harvey Lindenbaum was born in Brooklyn on March 29, 1935, to Abraham M. and Belle Lindenbaum. He was sandy-haired as a boy, when he earned the nickname that would stick with him for a lifetime. (“It’s common throughout the real estate industry for people simply to say, ‘Ask Sandy,’ ” Mr. Speyer said. “No last name was necessary.”) He graduated from Erasmus Hall High School in Brooklyn in 1952 and from Harvard College in 1956. The next year he married Linda M. Lewis, whom he had met when they were teenagers at Camp With-a-Wind in Pennsylvania. She survives him, as do their daughters, Erica Tishman and Laurie Lindenbaum, and six grandchildren. He also had a home on the Upper East Side of Manhattan. Mr. Lindenbaum earned his law degree from Harvard in 1959, after which he and his young family left for Oslo on a Fulbright fellowship. After returning to New York in 1960, he was soon tugged to his father’s side at Lindenbaum & Young on Court Street in Brooklyn. His father, known as Bunny, had a thriving real estate practice, representing Donald Trump’s father, Fred C. Trump, and the brothers Preston Robert Tisch and Laurence Tisch, who were then developing a half-dozen Loews hotels in New York.
