Diana Kingman was born in Philadelphia (1940) and knew at an early age that she wanted to be an artist. Kingman majored in Art History, including a Junior year in Paris in 1960. Upon return she moved to New York, where she graduated with a degree at Columbia University School of General Studies, then worked at the Bettmann Archive.
After travels in East Africa, marriage to a Canadian and two children she enrolled at the Pennsylvania Academy of the Fine Arts for their four-year program in painting. During art school and for a number of years afterward she worked in a realistic style, painting still lifes, landscapes and the human figure. In the mid-1980s her style evolved into abstract, eventually dropping all references to subject matter, painting in acrylics on paper.
Her work has been shown at galleries in New York, Philadelphia, Wilmington, and Lyon, France, and Kingman is represented in a number of corporate and private collections. Since 2004 she and her husband moved to Easton from the Philadelphia area where she actively continues to paint in her home studio.
