Founded in 1903, First Presbyterian Church of Hollywood became the largest Protestant congregation in North America during the mid-20th Century. This was attributed to the leadership of exceptional pastors such as Dr. Stuart MacLennan (1921-1940), Dr. Louis Evans (1941-1952) and Dr. Ray Lindquist (1953-1972) and renowned Sunday School curriculum pioneer and church Christian Education Director, Dr. Henrietta Mears. Dr. Mears was named one of the outstanding religious leaders of the 20th century by Christianity Today magazine. On a side note, Dr. Mears was also credited with saving the church from the original plan to build the Hollywood Freeway directly through the church property in the 1940s. She successfully lobbied for the freeway to curve around the church (thus the subsequent "bow" in the freeway between Franklin and Sunset).
