Sunday will be Muhammad Ali’s 74th birthday. Born Cassius Marcellus Clay Jr. on January 17, 1942 in Louisville, Kentucky to Cassius, Sr. and Odessa Grady Clay at Louisville General Hospital. A historical marker was placed in front of the house he grew up in on Grand Avenue in 2012. That boyhood home is being restored and renovated to be a museum to compliment the existing Muhammad Ali Center museum in downtown Louisville. Happy Birthday to The Greatest of all time!
