In the letter, I had asked him about a murder I’d been examining: the unsolved killing of a prominent Black politician in Chicago. I had reason to think he knew something about it.

Nearly six decades later, no one has been brought to justice for executing Lewis, thought to be the last elected official murdered in Chicago. Officially, the case is still open, but Ben Lewis has faded from public memory.

But he said he knew why Lewis was murdered and who was behind it.

Most of the stories about his political background came from reporters who heard them from either Lewis or other political operatives. These sources typically had an interest in portraying Lewis as a leader of his people, rooted in the community; or as a hustler and a player, claiming to advocate for young people and civil rights while looking for ways to profit from his position. The conflicting pictures were each grounded in truth but overstated. Lewis was both respected and manipulated. He projected strength even while forced to follow orders, and was well liked and gregarious though in the end a mystery even to many who spent time with him.

Around 1950, Lewis moved farther west, to the 24th Ward. Based in the Lawndale neighborhood, the ward was starting to lose its Jewish voters as they moved to less congested areas on the North Side and in the suburbs. At the same time, African-Americans looked for new opportunities in Lawndale after leaving the crowded South Side or the deep South.
