KEITH L. BROOKS founded the American Prophetic League of Los Angeles in 1930. He was the author of numerous Bible study courses, books, and tracts. Although Keith passed away in 1954, his wife, Laura, continued the ministry of the American Prophetic League until 1960. The League's Prophecy Monthly eventually merged with Moody Bible Institute's Moody Monthly. The published Bible study became the Teach Yourself the Bible Series from Moody Publishers.
