Louis died Nov. 2, 2014.

He graduated from St. Louis Country Day School in 1943 and matriculated at Princeton that summer. Shortly thereafter, he began his service of 28 months in the Navy and was discharged as a lieutenant junior grade. Louis then returned to Princeton and graduated in June 1948.

After graduation he went to work for Mercantile Trust Co. in St. Louis, where he became a loan officer in the bank’s commercial-lending department. Louis left his position as senior vice president at Mercantile Trust to join the Guaranty Trust Co. and became president of First National Bank of Clayton.

A relentless advocate of higher education among young women and men, he sat on the boards of both Mary Institute and St. Louis Country Day School. Louis also enjoyed activities in the area of sports such as hunting, fishing, golf, and scuba diving.

Louis was first and foremost a family man — including not only immediate and extended members, but their friends, his colleagues, and his customers. The class extends its sympathy to his wife, Geraldine; three sons, including Gerald ’81; three daughters; and 13 grandchildren, including Ashley ’13 and Catherine ’15.
