Early in his career, he deviated from his original "naif" style characteristic of Haitian art to experiment with classical era painting.
In 1952, Wah and his younger brother Bernard studied at Foyer des Arts Plastiques school in Port-au-Prince, picking up new techniques with such Haitian experts as Petion Savain, Dieudonne Cedor, Wilson Jolicoeur, Luckner Lazard and many others.
During that same year, he and his brother were commissioned by the Haitian government to restore the murals in the bicentennial section of the city, which encompassed certain other cultural centers and public buildings in the capital.
In 1971, during the peak of the Duvalier regime, Wah emigrated to the United States, relocating to Philadelphia where he would reside for the next thirteen years.
On one of many visits to his homeland, Edouard King Fong Wah died on September 27, 2003, in his beloved country of Haiti.
