Granville Oral Roberts was an American Methodist-Pentecostal televangelist and a Christian charismatic. He founded the Oral Roberts Evangelistic Association and Oral Roberts University.
As one of the most well-known and controversial American religious leaders of the 20th century, Roberts's preaching emphasized seed-faith. His ministries reached millions of followers worldwide spanning a period of more than six decades. His healing ministry and bringing American Pentecostalism into the mainstream had the most impact, but he also pioneered TV evangelism and laid the foundations of the prosperity gospel and abundant life teachings. The breadth and style of his ministry, including his widely publicized funding appeals, made him a consistent subject of contention among critics and supporters.
