Mr. Menard garnered listeners worldwide. Two of his albums were nominated for Grammy Awards, and he was a member of the Louisiana Music Hall of Fame. In 1994 the National Endowment for the Arts named him to a National Heritage Fellowship, the highest award in traditional arts.
“He was a consistently excellent songwriter and a consistently excellent musician,” Mr. Ancelet said in a telephone interview. “He was a prolific oral poet who had a remarkable knack for turning an observation, something he observed in our society, into a little nugget of poetry.”
Doris Leon Menard was born on April 14, 1932, in the sugar cane and cotton farm countryside of Erath. He grew up listening to country music on a battery-powered radio. He was 16 when his family moved into the town of Erath and he saw live Cajun music.
“That was the most exciting thing I had ever seen,” he told the journalist Tom Graves. “I couldn’t believe my eyes and ears that they were playing Cajun music and singing in French.”
At the time, Cajun French was forbidden in Louisiana schools, although the Menard family spoke it at home.
Mr. Menard ordered an $11 guitar from the Montgomery Ward catalog, learned to play rhythm chords and soon joined Elias Badeaux and the Louisiana Aces; later he became the band’s leader. He met Hank Williams at a club in New Iberia, La., in 1951; Williams gave him songwriting advice and urged him to prize Cajun culture. (Mr. Menard recorded Williams’s songs with country musicians in Nashville on his 1984 album, “Cajun Saturday Night,” his only one featuring songs in English.)
In 1952, Mr. Menard married Lou Ella Abshire, who died in 2001.
Mr. Menard is survived by two daughters, Rebecca Moreland and Doris Menard (called Boze); five sons, Kurt, Larry, Dick, Todd and Darrel; 17 grandchildren and 27 great-grandchildren.
Mr. Menard wrote “The Back Door” during one workday at a Phillips 66 gas station. “I had to fix flats and pump gas and serve the people,” he recalled, “so I was only able to get to the song between jobs.”
He paid $175 for a recording session and a pressing of 300 discs of “The Back Door,” which sold quickly enough to repay the investment within days. Dancers were soon demanding that the Louisiana Aces play the song multiple times at each gig. Other songs by Mr. Menard, among them “Un Homme Marie” (“A Married Man”) and “En Bas du Chêne Vert” (“Under a Green Oak…
