Daniel Rutherford
The son of Professor John Rutherford (1695–1779) and his wife, Anne Mackay, Daniel Rutherford was born in Edinburgh on 3 November 1749. He began college at the age of 16 at Mundell's School on the West Bow close to his family home, and then studied medicine under William Cullen and Joseph Black at the University of Edinburgh, graduating with a doctorate (MD) in 1772. From 1775 to 1786 he practiced as a physician in Edinburgh.
Joseph Franklin Rutherford
In 1926 he discredited Russell's teaching on the importance of Christian "character development" or personal "sanctification" and a year later discarded the teaching that Russell had been the "faithful and wise servant" of Matthew 24:45–47, warning that the desire to revere men was a snare set by the Devil. In May 1926 Rutherford released his book "Deliverance" at the Bible Student's convention in Kensington, England later interpreting the event as the fulfillment of the 1335 days of Daniel 12:12.
