Dudley J. “Couzin Dud” LeBlanc was born August 16, 1894 in Capitan Community near Youngsville, Louisiana, the son of Numa Dulze and Noemie LeBlanc. He attended school in Erath and Southwestern Louisiana Industrial Institute [now the University of Louisiana at Lafayette]. He served as a sergeant in the U.S. Army during World War I. On March 29, 1921, he married Evelyn Hebert (1897-1992) of Abbeville, Louisiana. The couple had six children. He died October 22, 1971 and is buried at St. Mary Magdalen Parish Cemetery in Abbeville.

LeBlanc was an entrepreneur. He started an ironing business in college, which by graduation was a flourishing tailor shop. He later sold tobacco, shoes and patent medicine, and launched a very successful burial-insurance company and a headache-remedy company. He was probably most famous for the invention, distribution and promotion of HADACOL, a vitamin/mineral supplement. He claimed it cured multiple illnesses. He organized caravans, including well-known entertainers, to promote its sale. He was also a newscaster, broadcasting in both English and French on local radio stations starting in 1946. Also a politician, LeBlanc was elected to the Louisiana House of Representatives in 1924. He was a member of the Louisiana Public Service Commission starting in 1926 and served as state senator, 1940-1944, 1948-1952, and 1964-1968. He ran for Governor twice but never won the elections. LeBlanc was proud of his Cajun heritage and authored two books: The True Story of the Acadians (1927, revised 1932) and The Acadian Miracle (1966). He organized several pilgrimages to Acadia/Nova Scotia, taking young women dressed as Evangeline to represent the various communities in Acadiana. He was also a member of the Catholic Church and donated the land on which St. Theresa Catholic Church of Abbeville now stands.
