George Washington Henry Jack (8 August 1855 – 15 December 1931) was a British Arts and Crafts designer and architect.
On his father's early death in 1860, the young Jack was taken by his mother, a pianist, back to Scotland, where they settled in Glasgow.
He then moved on to London, first joining the practice of Charles Vinall, and then, in 1880, the office of Philip Webb (1831–1915), the so-called "Father of Arts and Crafts Architecture".
He joined the Central School of Arts and Crafts on its foundation in 1896, teaching wood carving under the Principal, William Lethaby.
[1] Shortly before his death, aged 76 in December 1931, he was involved, with the architect Charles Winmill, in the renovations of St Margaret's Church, Barking.
