Dr. Richard Day Leonard and Katheryn Adelaide Campbell were married at the Hyde Park Methodist Church in Chicago on May 14, 1936. They met through the Epworth League group at the church, where “Dick” (born March 15, 1901) had a part time job in the office while working on his Ph.D. in church history at the University of Chicago. Their first date was a performance of Mendelssohn's Elijah.
