Sidney was the son of John Stevens and Eunice Hurd Dyer; grandson of William Dyer; and a descendant of William Dyre, an early settler of Massachusetts. He studied in classical schools in New York City; served in the Black Hawk War (1832-33); and returned to New York to study theology. He became a missionary among the Indians, and subsequently Secretary of the Indian Mission Board in Louisville, Kentucky. In 1852, he became pastor of the First Baptist Church in Indianapolis, Indiana. In 1859, he became District Secretary of the American Baptist Publication Society, a position he held 27 years. After retiring, he settled in De Land, Florida, and later moved to Germantown, Pennsylvania.

  1. Go Proclaim the Wondrous Story
