Leonard Sheldrake was a Brethren preacher, author and editor. He was born in England in 1885. His immediate family were not religious, but after the death of his father he came into contact with family members who were Baptist, and was himself baptised. He moved to Canada in 1905 beginning his association with the Brethren through the Broadview assembly in Toronto. Moving to Winnipeg, he abandoned his job in 1911 to devote himself to full-time ministry. He married Ada Pearl Clapp and they moved to America in 1913 where he began writing gospel tracts. He came into contact with William J. Pell who set up the Gospel Folio Press to produce these and other evangelical literature. He also produced three books: The Other Side of the Wall and Tabernacle Types and Shadows. He died on May 8, 1952.
