He returned to the District after graduating in 1964 from the University of Pennsylvania’s Wharton School of business with the hope of joining his father’s wholesale drug business. Mr. Estrin and a partner cobbled together $16,000 to convert an old barbershop on Pennsylvania Avenue into a disco, Tomfoolery, that became a sensation during the era of the frug and watusi. In 1971, he acquired a $2 million stake in American Health Services, an operator of general hospitals, psychiatric hospitals and nursing homes. Less than a decade later, he sold his interest for $36 million. Mr. Estrin and a frequent business partner, Abbey J. Butler of New York, made news for their corporate takeover in the early 1990s of National Intergroup Inc., a struggling Pittsburgh-based conglomerate reportedly valued at $5.5 billion. National Intergroup was essentially a holding company that included National Steel, one of the nation’s largest steelmakers, and the Foxmeyer wholesale pharmaceutical unit. He and Butler were co-chairmen and co-chief executives of the Phar-Mor discount pharmacy chain when it filed for bankruptcy in 2001, citing a slowing economy and increased competition.

His late father, David Estrin, was founder and chief executive of Spectro Industries, one of the largest wholesale drug suppliers on the East Coast. It later became part of McKesson Corp.
