At the same time, evangelicalism was continuing to influence the Presbyterian Church. In the late 1940s, the efforts of Christian educator Henrietta Mears at First Presbyterian Church in Hollywood, California, would make it the largest church within the denomination. First Presbyterian's emphasis on evangelism would have a profound influence on a number of prominent figures including Louis Evans Jr., founder of Bel Air Presbyterian Church; Richard C. Halverson, Chaplain of the United States Senate; and Bill Bright, founder of Campus Crusade for Christ. According to historian George Marsden, Mears "may have had more to do with shaping west coast Presbyterianism than any other person."
