Televangelist Oral Roberts passed away Tuesday from complications of pneumonia at the age of 91. Roberts rose from humble beginnings to spread Pentecostalism to hundreds of thousands of Americans through televised Sunday services. As a teenager, he said he was healed of tuberculosis and stuttering at an Oklahoma revival and several years later founded his own ministry. In the '40s, he began conducting crusades across America, personally laying hands on more than 2 million people, but he truly found his power when he brought TV cameras into his services in 1954. Roberts was a key figure in the rise of the religious right in the '70s and '80s. He founded Oral Roberts University and Oral Roberts Evangelistic Association.
