Joseph Quesnot (25 September 1895—31 March 1949) was a French politician who served as the first president of the Assembly of French Polynesia, and as a Senator.
Quesnot was born in Béziers and educated at the Lycée Vaucanson, though he did not complete his studies.[1] He moved to Tahiti, where he worked as an accountant, and as director of an import-export company.[1] He served as a municipal councillor in Papeete from 1933 to 1935, and as head of the chamber of commerce from 1933 to 1937.[1] He was elected to the Assembly of French Polynesia in 1945, and elected its first president in March 1946.[1] In December 1946 he was elected to the French Senate.[3]
He died at sea of a heart attack aboard the cargo liner in 1949 while returning to France.[4] [5] A street in Papeete was later named after him.[6]
