|Isaac Sheffield was an itinerant Connecticut painter who specialized in portraits of sea captains, whalers and figures. He was born in Guilford, CT in 1798 and by 1838 he was living in New London. At least five full-sized paintings and three miniatures, all portraits, are currently known to exist. Only one bears a signature, a gouache of a young girl painted in 1833 which is his earliest known work and the only one not created in his preferred medium of oil on canvas. The other four of the five portraits are of sea captains and all are unsigned. One of his captain's portraits is housed in the permanent collection of the National Gallery of Art in Washington D.C., and a second of Captain Peter Coffin is in the collection of the U.S. Gallery at the Australian National Maritime Museum in Sydney. Records show that Sheffield purchased a burial plot in Stonington, CT from Captain Thomas Robinson in the early 1840's. The cemetery, still located at Stonington Point, is likely his final resting place.
