A lifelong learner, he had a deep love for studying Scripture and was so committed to understanding God's Word that he learned Greek in order to read the New Testament in its original language. His passion for knowledge, faith, and teaching touched countless lives and leaves a lasting legacy of wisdom, devotion, and service.

He was preceded in death by his wife, Shirley Leonard; and parents, Fred and Florence Leonard.

Survivors include his daughters, Amanda Maple, Virginia Dooley; son, Leon Leonard (Caralyn); 7 grandchildren and 5 great-grandchildren.
