Born Dec 29 1932 in New York State, Hinman is an artist and sometime professional baseball player. After his artistic training, he served in the army for two years and then taught mechanical drawing. From here he combined these skills and specialized his artistic talents, focusing on abstract representation of 3D shapes on canvas. Using a technique of underpinning the canvas with reverse ribs to provide contours to his works, he then uses colour to complement or contrast the physical shape.
