Marquis Childs, James Deakin, Richard Dudman. Three big-timers I recall working at the P-D during the time period you mentioned.Good to see a winner from the Houston Chronicle (several friends work there). If I'm not mistaken, that was the largest paper that hadn't won one. The Sun Sentinel in Fort Lauderdale also was near the top of that list until it broke through a few years ago.
Also, I think that's the first Pulitzer for the St. Louis Post-Dispatch since the '70s. It was considered one of the two or three best papers in the Midwest during my youth in the '60s and early '70s.
