Former President Barack Obama remembered Black as an "icon."
"Over his 102 years, Tim was many things: a veteran, historian, author, educator, civil rights leader, and humanitarian. Michelle and I send our thoughts to his family, and everyone who loved him," Obama said in a post on Twitter.

"May Chicago's beloved son rest in peace," he added.
