Here are two shots of the retro-y building that houses The Chicago Defender at 2400 South Michigan. The venerable Defender newspaper has covered the African-American community since 1905.
According to the AIA Guide to Chicago, it was designed by Philip B. Maher to house the Illinois Automobile Club. The Defender moved in sometime in the 1950s. I'm presuming it was after they vacated their landmarked building at 3435 S. Indiana.
Last week, before I pulled out my AIA guide (duh), I called and spoke with the Defender's receptionist.
She said she didn't know who the architect was and transferred me to a line that went dead. I called back and said I was disconnected. She said that was probably because no one knew who the architect was.
"I don't think anybody here knows," she said. "We just work here."
