Dr. Moore also gave his 18th century Loudoun County farm, Lanesmoore, to the National Wildlife Federation in 1975 for use as a conservation and education center. Loudoun County would later purchase the farm for use as the Claude Moore Park in Sterling. This park is now one of the most visited sites in Loudoun County, and features an environmental learning center and farm, which includes exhibits funded by the Claude Moore Charitable Foundation.
Dr. Claude Moore was born in Danville, Virginia in 1892. He would later describe his childhood in the Southwest Virginia towns of Radford and Roanoke as one of poverty, steeped in the values of hard work and thrift.
After two years at Roanoke College, young Claude entered the University of Virginia Medical School, where against the dean's advice, he also played varsity football, relying on his photographic memory to enable him to pursue sports in addition to his demanding academic schedule. He graduated in 1916 and went on to complete his medical internship at New York Hospital. In 1917, at the onset of World War I, Dr. Moore volunteered for the Army, received medical training in military surgery at Mayo Clinic, and served as a first lieutenant in France.
Following World War I, Dr. Moore returned to Roanoke, where he practiced for seven years before joining the staff of Mayo Clinic to study radiology. In 1930, he moved to the District of Columbia and taught at the George Washington University. A professor in radiology, Dr. Moore served as the first chairman of the university's radiology department, developing it into a modern facility for the time. He later established a lucrative independent practice.
Dr. Moore began investing in undeveloped Northern Virginia land in 1931, acquiring many of his holdings at public auctions. He typically stocked these properties with cattle or sheep, or leased them to tenants for farming. When he retired from the practice of medicine in 1956, Dr. Moore turned his full attention to land investments and, for a time, was one of the largest landowners in Loudoun County, Virginia.
In 1941 on the day before Pearl Harbor, Dr. Moore purchased Lanesmoore, his home, at auction. On the property, which included an old schoolhouse, he built a log cabin out of materials he salvaged from other properties he owned, constructing its fieldstone chimney by hand during his late eighties.
Dr. Moore, who passed in 1991 at the age of 98, established the Claude Moore Charitable Foundation in 1987 to continue his philanthropic legacy.
