Oliver Boyce Greene (1915–1976) was an American Independent Fundamental Baptist preacher and evangelist whose dynamic ministry left a significant mark on 20th-century evangelical Christianity. Born on February 14, 1915, in Greenville, South Carolina, he was the sixth of nine children in a farming family. Greene described his early life as wayward, marked by a hard heart and sinful behavior, until his conversion at age 20 on September 9, 1935, influenced by his mother’s and sister’s prayers and a sermon on Romans 6:23. Five months later, on February 29, 1936, he felt called to preach. He briefly attended North Greenville Baptist College before entering full-time ministry, and was ordained on July 24, 1939, at Morgan Memorial Baptist Church in Greenville. On September 10, 1939, he married Aileen Hazel Collins, with whom he had three sons: Oliver Boyce Jr., Thomas, and David. Greene’s preaching career spanned from 1939 to 1968, during which he conducted revival meetings in tents and churches across the eastern United States, recording over 200,000 professions of faith. Known for his fervent, uncompromising style, he preached from the King James Bible, focusing on salvation, grace, and the second coming of Christ. In 1956, he founded The Gospel Hour, Inc., launching a radio ministry, The Gospel Hour, which began on one Georgia station and grew to be syndicated nationwide, airing on 150 stations at its peak. He authored over 100 books and booklets, including From Disgrace to Grace, reflecting his personal testimony. Greene continued preaching until failing health forced him to retire from tent revivals in 1968. He died of a cardiac aneurysm on July 26, 1976, in Greenville, and was buried in Woodlawn Memorial Park, leaving a legacy of bold evangelism and a radio ministry that persists through taped sermons.
