John ('Jack') George Mennie, A.R.M.S. D.A.(ABDN). ARMS., (26 November 1911 – 24 August 1982) was a Scottish artist who came to public attention in 2011 for his many contemporaneous drawings of his life as a prisoner of war during the Japanese occupation of Singapore and Thailand in World War II. The drawings were made in secret depicting scenes of daily life and personalities in the camps in Singapore and Thailand, working on the Death railway. They also uniquely documented the Selarang Square Squeeze when some 17,000 prisoners were forced to crowd in the barracks square for nearly five days with little water and no sanitation until they signed a 'promise not to escape'.
