Mr. Fisher was a member of the the Fisher Brothers real estate dynasty that helped reshape the city's skyline in recent decades with the luxury high-rises and office towers they built, owned and managed in Manhattan. The Fishers, together with others like the Rudins, Dursts, Roses, Tishmans and Resnicks, are considered one of the royal families that over two or three generations have molded the Manhattan real estate market.
Over the years Mr. Fisher lavished attention and money on military and veterans' projects. He gave more than $25 million to the establishment of the Intrepid Museum. He also set up a foundation that sent $10,000 checks to families of the 241 people who died when a Marine barracks was bombed in Beirut in 1983.
The family business was started earlier in the century by his father, Carl Fisher, who became a force in real estate as a general contractor building apartment houses in New York.
He and his older brothers Martin and Larry formed Fisher Brothers as the privately held core of a conglomeration of construction, holding and management businesses. Mr. Fisher was for many years in charge of the company's leasing operations.
Fisher Brothers, which controls more than five million square feet of office towers, now is largely operated by five of his nephews and great-nephews.
Martin Fisher died in 1976. In addition to his wife of more than 50 years, the former Elizabeth Kenowsky, Zachary Fisher is survived by his stepson, Bill Crovello; his brother Larry, managing partner of Fisher Brothers, and his sister, Ginny Ross, all of Manhattan.
