Alexis I. du Pont Bayard

Bayard died in Philadelphia, Pennsylvania, on September 3, 1985, during heart-bypass surgery at Graduate Hospital. He was buried at the Old Swedes Episcopal Church Cemetery in Wilmington, Delaware, alongside his father, grandfather, and great-grandfather.

In 1961 he joined what had been the Herrmann & Duffy law firm in Wilmington; at the time of his death the firm was Bayard, Handelman & Murdoch.

After his defeat by Williams, Bayard resumed his law practice in Wilmington and remained an active supporter of the Democratic Party. In 1954, he served as campaign chairman of the Delaware Democratic Committee. In 1967, he became the state Democratic chairman. In 1970, he became a member of the finance committee of the Democratic National Committee and held this position until his death.

Bayard lost a bid for a seat in the United States Senate in 1952 to the incumbent Republican U.S. Senator John J. Williams. Bayard's inexperience and aristocratic roots compared unfavorably to Williams' "rags-to-riches" rise from chicken farmer to national figure. These factors, along with Williams' reputation for honesty, integrity, fairness, and bipartisanship in the U.S. Senate and the popularity of the Republicans' U.S. presidential candidate, Dwight D. Eisenhower, led the incumbent to a ten-point victory over Bayard at the polls.

A war era veteran with a well-known name, the 30-year-old Bayard was elected lieutenant governor in 1948, defeating Republican Chester V. Townsend Jr. of Dagsboro, who was speaker of the Delaware House of Representatives. He served as lieutenant governor from January 20, 1949, until January 15, 1953. In 1948 he also served as an alternate delegate to the Democratic National Convention.

He married Jane Brady Hildreth on April 24, 1944. He had six children: Alexis I., Eugene H., Richard H., John F., William B. and Jane H.

Bayard attended St. Paul's School in Concord, New Hampshire. He graduated from Princeton University in 1940. He later attended the University of Virginia School of Law and was admitted to the bar in 1948.
