Bonhomme was born by the sea and the tropical forest in northwest Haiti in 1963. During his early childhood, he spent a great deal of time fishing and farming with his father, and consequently lived in intense communion with nature. At the age of 12, he developed an interest in painting. He started to paint marine life and portraits, developing his personal technique by researching calligraphy and cartography. By 1990, his canvasses reflected his expertise in the field. He painted birds in an environment of luxuriant vegetation. His artwork has been successfully exhibited around the world, especially in Europe, Asia, and the United States.
