Joseph Gurney Barclay

Joseph Gurney Barclay (9 February 1879 - 15 April 1976) was a British banker and Evangelical Anglican-Quaker missionary.

Barclay was the fourth son of Robert Barclay of High Leigh and the grandson of Joseph Gurney Barclay, an astronomer. He was educated at Harrow School and Trinity College, Cambridge. He entered the family bank (Barclay's Bank), but left in 1908 to become a missionary to Japan. He returned to Britain in 1926 to work for the Church Missionary Society.

An obituary written by the Bishop of Worcester, Robin Woods was published in The Times.

He married twice, and his children included Sir Roderick Barclay KCMG (died 1996) by his first wife, and the missionary Oliver Barclay by his second wife.
