Wilson was born in
Roseland near
Amite, the seat of
Tangipahoa Parish, one of the "
Florida Parishes" of southeastern Louisiana. He was the second-youngest of seven children of
Harry D. Wilson, the
Louisiana Commissioner of Agriculture and Forestry from 1916 to 1948 and a former member of the
Louisiana House of Representatives. While Wilson presented himself as Cajun in his act, it is unclear if he had any actual
Acadian or
French ancestry. His father Harry Wilson was of Welsh descent. Justin Wilson described his mother, the former Olivet Mintern Toadvin (1880–1976), as Cajun, but she has no known ancestors who either were
Acadian, lived in the
Cajun regions of Louisiana, or emigrated from
France. (She did, however, teach Justin how to cook.) Her surname Toadvin derives from a native of
Guernsey who immigrated to
Maryland circa 1675. The Florida Parishes, where the family lived, were not part of the
French or
Spanish colonies of Louisiana. Wilson began his career as a
safety engineer while he traveled throughout
Acadiana. The safety lectures that he made to refinery workers prompted him to become a Cajun storyteller. He remembered it this way on the back cover of
The Justin Wilson Cook Book: Way back when I first started as a safety engineer, I took myself pretty seriously, and I found I was putting my audiences to sleep. So having lived all my life among the Cajuns of Louisiana, and having a good memory for the patois and the type of humor Cajuns go for, I started interspersing my talks on safety with Cajun humor. Wilson later recorded several comedy albums, beginning with
The Humorous World of Justin Wilson on
Ember Records. He also recorded several albums for
Jewel Records on the Paula label and a few for
Capitol Records. He later appeared as a guest on the popular
CBS series
The Ed Sullivan Show. He was known for the
catchphrase, "
I gar-on-tee!" (I guarantee). As a comedian, Wilson was enormously popular in Louisiana, and to a lesser degree in neighboring states, but his humor may have been a little too specifically regional to enjoy the wider popularity of Southern comics such as
Jerry Clower or
Archie Campbell. He composed ten songs, as well as composing the background music for his cooking show, and recorded one album of Christmas songs with a jazz band. Wilson wrote seven Cajun
cookbooks and two books of Cajun stories. He hosted several
cooking shows on Louisiana Public Broadcasting (LPB) during the 1980s and 1990s including “Louisiana Cookin’,” which was distributed nationally on Public Broadcasting Services (
PBS) and at least one in 1975, for Mississippi Educational Television (
ETV), that combined
Cajun cooking and humor. Some episodes were aired from the studios of
WYES-TV in
New Orleans. Wilson appeared in a series of television commercials for Cajun Spice
Ruffles potato chips during the late 1980s. In 1997, he published the cookbook "Looking Back", which combined his first two cookbooks in a hardcover format, with additional photos, and notes on how his cooking techniques had changed (e. g., using olive oil instead of
oleo) since those early cookbooks were published. A companion series was produced, also titled "Looking Back" and broadcast nationwide on PBS, which was a repackaging of Wilson's first cooking show from 1971, with new intros by Wilson himself. This was the first time the 1971 programs were ever seen nationwide, as they were originally produced by Mississippi Educational Television and, at that time, were only broadcast regionally. Southern author Harnett T. Kane said of Wilson: "I know of no one [else] who portrays the Louisiana Cajun as well, so skillfully and entertainingly". But Wilson faced criticism from many Cajuns who viewed his humor as degrading, especially from a non-Cajun essentially doing a Cajun impression.
James Domengeaux, a former member of Congress and founder of
CODOFIL, considered Wilson a degrader of the Cajun people. ==Politics==
