Frank Bartleman (1871-1936) was an early Pentecostal evangelist who recorded the beginnings of the Pentecostal Movement. He and his wife, Anna, and their family went to Los Angeles in December 1904. Shortly thereafter, their oldest daughter, Esther, who was just three years old, died. This heartbreaking loss made a deep impact on Bartleman and led him to rededicate his life to God's service. He was a participant in the Azusa revival and other early Pentecostal meetings in the Los Angeles area. Bartleman was an itinerant evangelist for 43 years, eventually preaching across the United States and all over the world. He wrote more than 500 articles, 100 tracts, and six books. He is remembered for his passion for increased unity and spiritual renewal among Pentecostals.
