I used Google to identify the LSU president as Gen. Troy H. Middleton.
From Wikipedia:
https://en.wikipedia.org/wiki/Troy_H._Mi...presidency
"Lieutenant General Troy Houston Middleton (12 October 1889 9 October 1976) was a distinguished educator and senior officer of the United States Army who served as a corps commander in the European Theatre during World War II and later as president of Louisiana State University (LSU). He is best known for his decision to hold Bastogne during the Battle of the Bulge, contrary to the recommendation of Lieutenant General George S. Patton, Jr., Commanding General (CG) of the United States Third Army."
....
"As the university president, Middleton was constantly involved in personnel decisions, some of them making national news. One such ordeal occurred in February 1955 when the Board of Supervisors decided that it was time for the head football coach, Gaynell Tinsley, to be relieved following a break-even record in seven years. His successor, Paul Dietzel, was a 29-year-old assistant coach at the United States Military Academy. Dietzel had a rough beginning at LSU with three losing seasons, and calls for his removal became louder. Middleton supported Dietzel, however, and in his fourth season as coach the LSU Tigers not only had an undefeated season, but also won the Sugar Bowl and were declared the national champions."
Now I understand why the main library would be named after him.
Geaux Cardinal!
