About the Lecture Series
The William Ardis Marbury, Jr. and Virginia Lomax Marbury Lecture Series began in 2006 and is named after William Ardis Marbury, Jr. and his wife Virginia. The pair, both Louisiana Tech graduates, established William A. Marbury & Company, Inc., a managing general insurance agency. This corporation grew to be the largest agency in Louisiana, and one of the largest in the South. The general agency was sold in the 1950s to Commercial Union Insurance Company with the Ruston branch remaining the company’s largest in the country. In 1959, the Marburys and their associates founded Bankers Life of Louisiana, which became the largest credit life insurance writer in the state. Today the Marbury Companies continue to thrive in Ruston, serving the banking, investment, and insurance sectors. The companies founded by the couple continue to have a major impact on the economy and the community.
