Dudley Joseph LeBlanc[1] (August 16, 1894 – October 22, 1971)[2] was an American entrepreneur and politician. He created the patent medicineHadacol and promoted it through the 'Hadacol Caravan' which featured major celebrities of the day including Mickey Rooney, Ava Gardner, Cesar Romero, Hank Williams, and many others. Williams began writing the song 'Jambalaya' while traveling on the Hadacol bus, listening to the Cajun conversation.
In his Gubernatorial campaign, one of Leblanc's plans was to pay a monthly stipend to the elderly. Huey Long subsequently adopted the idea in his nascent campaign for President. Franklin D. Roosevelt got the idea from Long, and it became the modern Social Security system.[5]
LeBlanc was a contestant on the 1 March 1951 edition of You Bet Your Life in which he described his political career.
