Tennant’s evanescent works have conquered private and public collections. The influence of academic French painting on his art shows in his characters’ modelling while there is no doubt about the era he depicts thanks to the details he represents. Tennant followed a classical training and received a B.F.A. from the Maryland Institute College of Art, in Baltimore, and an M.F.A. from the New York Academy of Art, in New York City.
Tennant also was the Director of Graduate Fine Art Painting at Academy of Art University, in San Francisco. He had been an instructor there since 1998. Tennant has taught Museum Copying at the Louvre, Paris, at the Metropolitan in New York, and the Legion of Honor in San Francisco.
