(Saint-Ouen 1911 - 1993 Orléans)
Manessier studies first in Amiens, then, from 1931 on, in Paris. In 1935, he meets the painter Roger Bissière at the Académie Ranson and briefly becomes his student. Identifying color as the primary medium of his art, he begins in 1940 to build an oeuvre of abstract lyrical compositions. Among his major creative achievements are colorful church windows, including those he designs for Basel’s Church of All Saints in 1952.
