Horace Tracy Pitkin (1869–1900) was a missionary of the American Board of Commissioners for Foreign Missions who was killed in China during the Boxer Uprising in 1900. Yale China Mission, (now the Yale-China Association), was founded in his memory.
Pitkin was born Philadelphia. On his mother's side, he was a descendant of Elihu Yale, the founder of Yale College. The Pitkin family settled in Manchester (Connecticut). Entering Phillips Exeter Academy in Exeter, New Hampshire, in 1884 Pitkin took a leading role in the campus Christian Endeavor movement. Entering Yale in 1888, he excelled in music, writing, and volunteer activities. He was widely admired for his sunny disposition and strong convictions.
In the summer of 1889 at Dwight L. Moody's Northfield (Massachusetts) School, he signed the Student Volunteer Movement (SVM) pledge, indicating his intention to become a missionary. Following graduation from Yale in 1892, he entered Union Theological Seminary, New York, then spent an interim year as traveling secretary for the SVM. In 1894, with his fiancee, Letitia Thomas, a graduate of Mount Holyoke College, Massachusetts, he offered himself for service with the American Board of Commissioners for Foreign Missions.
Pitkin graduated from Union Theological Seminary in 1896, then he and Letitia were married. The couple sailed from New York in November 1896, traveled through the Holy Land, Egypt, and India before landing at Tianjin in May 1897. At Baoding, in present-day Hebei province, he joined the ABCFM mission.
Pitkin was beheaded by Chinese Boxers while defending two single missionary women. In all, fourteen Presbyterian, Congregational, amid China Inland Mission missionaries were killed at Baoding. Letitia and an baby son had returned to America.
Pitkin's death motivated several students at Yale to create an organization to send missionaries to China. One said that "Pitkin's martyrdom... made me determined to see if possible that Pitkin's sacrifice was atoned for somehow by us as Yale men." The Yale Mission in China was established in June 1901.
