D. Roosevelt, having spent time with him at Warm Springs, Georgia. During McFeely's time as the head of school (1948–1966), the school constructed the Alumni Gym, Hallowell Hall, McFeely Library (so named after his death), and Walton Center. McFeely retired because of poor health from polio and died within the year. During the mid-1950s, Julian Bond, later a prominent civil rights leader, attended George School. While Bond encountered some cases of racism while attending there, he was impressed by the anti-racist philosophy of the school and first encountered ideas of non-violence and social action. One event, in particular, involved Bond, a varsity athlete, going to Philadelphia with his white girlfriend while wearing George School apparel. Upon returning, the school dean reprimanded him. George School has claimed it was enforcing a policy of not wearing George School insignia apparel off-campus; Bond alleged that the reprimand was racially-motivated and "That was just like somebody stopping you and slapping you across the face." Eric Curtis, an Englishman and a former faculty member at Earlham College, was brought in to be the headmaster after McFeely, serving from 1967 (there was an interim head for 1966–67) until 1979. Curtis oversaw a tumultuous time of change in the social relationships within the school, as assertive students and younger faculty battled older faculty and administrators (and George School Committee) over various procedures. The two significant new buildings in Curtis' time were the Science Center and the Sports Center. David Bourns was head of school from 1979 to 2001 when he left to head the Paul Cuffee charter school in Providence, Rhode Island. Bourns' time began as a recentering after the tumult of the previous decade. A new emphasis on academic rigor was enforced, along with more focused activism: the school built an Alternative Energy Center in the mid-1980s and for several years hosted a regional "Peace Fair." Nancy Starmer, the first non-member of the Society of Friends to head the school, succeeded him. On September 18, 2007, Barbara Dodd Anderson, George School Class of 1950, gave a gift of $128.5 million to George School. The gift is to be received over twenty years from an irrevocable charitable lead trust and is the single largest gift to an existing private school in U.S. history. The gift has its origins with billionaire businessman and philanthropist, Warren Buffett. Buffett was a student of Anderson's father, David Dodd, an economist and
