Frank Bartleman (December 14, 1871 – August 23, 1936) was an American preacher, evangelist, and writer whose ministry ignited and chronicled the 1906 Azusa Street Revival, a cornerstone of modern Pentecostalism. Born near Carversville, Pennsylvania, to Frank Bartleman, a strict German Catholic immigrant, and Margaret Hellyer, an American Quaker of English-Welsh descent, he was the third of five sons in a farming family. Converted at 22 on October 15, 1893, in Philadelphia’s Grace Baptist Church under pastor W.W. White, he briefly studied at Temple University and Moody Bible Institute before leaving formal education for ministry, shaped by Salvation Army and Holiness influences. Bartleman’s preaching career began in 1894 with the Salvation Army, Wesleyan Methodists, and Pillar of Fire, evolving into a Pentecostal focus after his 1905 move to Los Angeles. There, his fervent prayer and sermons sparked the Azusa Street Revival under William J. Seymour, where he preached racial unity and Spirit baptism, documented in over 550 articles, 100 tracts, and six books, including How Pentecost Came to Los Angeles (1925). His global ministry included China (1908–1916) and Europe (1912–1914). Married to Anna Ladd in 1900, a Bulgarian adoptee of Methodist missionaries, they had four children—Esther (died infancy), George, Ruth, and John—before her death in 1929. Bartleman died at age 64 in Los Angeles, California.
