Story highlights Restaurant tycoon Mike Ilitch died on Friday at the age of 87

The Detroit native had paid for Rosa Parks' apartment in a safer area of the city

(CNN) Those who knew Mike Ilitch, the Little Caesars founder and Detroit Tigers owner who died last Friday, have spent the past few days fondly remembering his impact on friends, on Detroit residents, and on the sports community.

Ilitch also had an impact on the daily life of one of the most iconic figures from the civil rights movement.

For more than a decade, Ilitch had quietly paid for Rosa Parks' apartment in downtown Detroit, according to CNN affiliate WXYZ

That story came to light thanks to Damon Keith, a Detroit native and federal judge

"They don't go around saying it, but I want to, at this point, let them know, how much the Ilitches not only meant to the city, but they meant so much for Rosa Parks, who was the mother of the civil rights movement," Keith told WXYZ.
