ALSO From the back cover of the 1954 Penguin edition of “One of Our Submarines”:

Edward Young was born in Trinidad, West Indies, in 1913. He was educated at Highgate and at 18 took a job as office boy in a publishing firm, where he gradually became interested in printing and design. When Penguin Books started in 1935 he was production manager, he designed the cover, and drew the Penguin device. In April 1940 he joined the Royal Naval Volunteer Reserve (R.N.V.R.), and four months later entered the submarine service, and was the first R.N.V.R. officer to command an operational submarine. After the War he joined Rupert Hart-Davis, who was then about to start his new publishing firm, and became the director in charge of production and design. … He is married, and has two daughters.”
