Eugene H. Webb, who was raised in racially segregated Alabama with modest ambitions, but who after transplanting himself to Harlem established what became the nation’s largest Black-owned real estate management company, died on April 5 at his home in Mount Vernon, N.Y. He was 102.

His death was confirmed by Webb & Brooker, the New York-based management, leasing and sales company he founded with George M. Brooker in 1968, which oversaw thousands of apartments generating tens of millions of dollars in rents.

In addition to his role at the firm, where he became chairman emeritus, Mr. Webb was among the founders of Carver Federal Savings Bank and of Freedom National Bank (which closed in 1990 during a recession). Both banks earned a reputation for lending to prospective Black and Hispanic home buyers in neighborhoods like Harlem, where applicants had been reflexively rejected by other banks.

Mr. Webb also played a prominent role in Harlem’s contentious redevelopment history, when new projects often raised fears that old Harlemites would be pushed out. He was part of the team that built the $60 million Renaissance Plaza on West 116th Street in the late 1990s, which includes 240 cooperative apartments and more than 60,000 square feet of retail space.
