John Wilbur Chapman (June 17, 1859, Richmond, Indiana – December 25, 1918, New York City) was a Presbyterian evangelist in the late 19th century who traveled with gospel singer Charles Alexander.
In late 1895, Chapman was appointed Corresponding Secretary of the Presbyterian General Assembly's Committee on Evangelism, overseeing the activities of 51 evangelists in 470 cities.
In 1905, John H. Converse, a wealthy Presbyterian philanthropist, offered to underwrite Chapman's expenses if he would re-enter the evangelistic field full-time.
Chapman accepted the offer and in 1907, joined forces with popular gospel singer Charles McCallon Alexander to launch the "Chapman-Alexander Simultaneous Campaign."
It was at a similar Chapman-Alexander event in North Carolina that the legendary King James Only proponent, David Otis Fuller, committed to the Christian faith.
Chapman's biography reports, "The first Chapman-Alexander worldwide campaign left Vancouver, British Columbia on March 26, 1909, and returned on November 26, 1909.
The itinerary included: Melbourne, Sydney, Ipswich, Brisbane, Adelaide, Ballarat, Bendigo, and Townsville in Australia; Manila in the Philippines; Hong Kong, Kowloon, Canton, Shanghai, Hankow, Peking and Tientsin in China; Seoul, Korea; Kobe, Kyoto, Tokyo, and Yokohama in Japan.
[2] Chapman became heavily involved in the Stony Brook conferences in his later years, seeing that it had the most promise of flourishing because of its close proximity to New York City.
