Joshua Edward Synge ('Josh') Cooper CB, CMG (3 April 1901 in Fulham, London – 24 June 1981 in Buckinghamshire) was an English cryptographer.
Josh was the eldest son of Richard Edward Synge Cooper and his wife Mary Eleanor Burke who were married in Dublin exactly a year before his birth.
[2][1] His brother Arthur (born 1916) was also a linguist (Chinese and Japanese) at the FECB then FRUMEL; a bit eccentric but said to be a model of sanity compared with Joshua.
Postwar Arthur translated Li Po and Tu Fu, a book of Chinese lyric poems, for the Penguin Classics series.
