Samuel Ridout's father died when he was only one his father died, and at age 5 his mother and his grandfather undertook to raise the boy. Of this devoted and godly man, Mr. Ridout ever spoke in the highest terms of appreciation, and often mentioned how greatly he was indebted to him for training in the nurture and the admonition of the Lord. He determined to enter Princeton Seminary, where he graduated in 1880.
He had a long ministry of 40 years. He followed F. W. Grant in the Editorship of "Help and Food," and was associated with him in the work of the Numerical Bible. He also wrote Sunday School classes for the Sunday School Visitor. For nearly 30 years he compiled the Treasury of Truth Almanac and Counsellor, and in the work of the Bible Truth Depot his help and counsel were ever a source of inspiration and comfort.
