Clark, who attended Germantown Academy and the University of Pennsylvania.[1] He married Lydia Jane Newhall (1858-1936) on October 31, 1882, in Philadelphia. They had two sons, George Newhall Clark (1887-1906), who died while at Harvard of influenza; and Sydney Procter Clark; and two daughters, Frances Clark Stoddard, and Christine Clark Willetts.[1]
He became a trustee of the Pomfret School, and gave the school a dormitory, Dunworth, in 1905. In 1907, he donated the Clark Memorial Chapel to honor his deceased son.[1]
Clark was a prominent cricketer, playing as a right-handed middle-order batsman and a right-arm medium bowler, bowling in the round-arm style. His career in front-rank American cricket lasted from 1877 to 1906, during which he played for many different sides.[2]
Between 1880 and 1897, he appeared in 27 matches that are considered as "first-class cricket", some of them all-American games and others against touring teams from England.[5] His highest first-class score was an innings of 147 made in a rather strange match in 1894 in which his team batted for the whole of the two days allotted to the game, which was therefore left drawn.[6]
His brothers Herbert, Joseph, and Percy also played first-class cricket, though Joseph was better known as a tennis champion.
