(New York Times) — Generations of the city’s black business leaders have played a vital yet largely unsung role in the struggle for civil rights and black political and economic empowerment in Chicago — from the Great Migration in the early 20th century to the Rev. Dr. Martin Luther King Jr.’s battle for open housing in the 1960s to the victory of Harold Washington in the 1980s to the making of a black president on a warm November night in Grant Park two years ago. The tradition continues. With the Feb. 22 mayoral election looming, the current generation of prominent Chicago black business men and women has formed a candidate search and support committee. Informally known as the Business Leadership Council, the group, which has about 25 members, hopes to help replicate the energy and minority voter interest that led to the election of Mr. Washington as the city’s first black mayor nearly 30 years ago.
