William Grosvenor Congdon was born on April 15, 1912, in Providence, Rhode Island, the second child of Gilbert Maurice Congdon and Caroline Rose Grosvenor, who married in 1910. Both parents came from rich families: the Congdons dealt in iron, steel and metals, while the Grosvenors owned a textile manufacturing business in Rhode Island. They had five children, all sons. William Congdon was the cousin of Isabella Stewart Gardner (the American, poet-critic Allen Tate's second wife) who is spoken of in personal letters between Allen Tate and Jacques Maritain (see pages 77–79 in John M. Dunaway's Exiles and Fugitives: The Letters of Jacques and Raissa Maritain, Allen Tate, and Caroline Gordon).After graduating from St. Mark’s School of Southborough, Massachusetts, he studied English Literature at Yale University and graduated in 1934. His cousin on his mother's side was poet Isabella Gardner. For three years, Congdon took painting lessons in Provincetown with Henry Hensche, followed by a further three years of drawing and sculpture lessons with George Demetrios in Boston and then Gloucester. For some months in 1934-35 he frequented the Pennsylvania Academy of the Fine Arts in Philadelphia.
Congdon died on April 15, 1998, his 86th birthday. He painted up to a few days before his death. The palette range in his last painting reveals unusual combinations and contrapositions: for example, the sky in his very last work - Three Trees - is a startling innovation.Wikipedia
