Washington Merritt Grant Singer (1866–1934) was an American-born British heir, philanthropist and prominent racehorse owner.
Born in Yonkers, New York he was the third child of Isabella Eugenie Boyer and sewing machine magnate, Isaac Singer.
After he received his inheritance upon his father's death, he originally planned to run a ranch in the American West, but after spending time hunting in Devonshire with his brother, Mortimer Singer, he decided to stay in England and become a racehorse owner.
[2] A Thoroughbred horse racing enthusiast, he won the 1905 St. Leger Stakes with the colt Challacombe, trained by Alec Taylor, Jr. and the 1932 2,000 Guineas with Orwell.
[1] In 1903, Singer purchased Norman Court, West Tytherley, Hampshire,[6] an 18th-century country house[7] with a 20,000-acre (81 km2) estate that included the Hampshire parishes of Buckholt and Frenchmoor, and in Wiltshire the village of West Dean and parts of Farley and Pitton.
