Cassell, John (1817-1865), founder of the publishing firm widely known as Cassell, Petter, and Galpin, and now as Cassell and Co. The difficulties that attended his own education set him to trying to make it easier for other people, and he in 1850 issued The Working Man's Friend, and in 1852 The Popular Educator, which has been a boon to many a man and boy who were trying to educate themselves. In 1859 he entered into partnership with Messrs. Petter and Galpin, since which time the publications issued by the firm of every variety of interest are legion.
