Originally from France, Gravereaux and his family escaped under the German invasion, ultimately ending up in New Canaan. He attended the one-room Carter Street School, where his interest in art began by studying with noted artist Judy Bell.
As a Christmas present in 1995, his wife, Kathy, enrolled him in a watercolor class at the Silvermine School of Art, where he continues to study. He trained with George Sutherland for many years, learning numerous styles and painting methods.
Gravereaux enjoys watercolor painting as a hobby. His art has been on display at various venues in the local area, and he has been commissioned to paint many outdoor scenes of homes, waterfronts and country landscapes.
