The son of a Wigan cobbler, Isherwood is reported to have started painting at the age of 9. Early in his life he worked in the accounts department of a local factory and later helped out in the family shoe business but this did nothing to dim his ambition to become an artist.
He studied at Wigan Technical College School of Art from 1934 to 1953 but his style is very individualistic. He copied no-one. Like Lowry before him, his art was his interpretation of what he saw. Lowry displayed Isherwood's work in his own home and this meant a great deal to Isherwood.
He held over 200 one man shows, regularly exhibiting at Oxford and Cambridge Universities. The Prince of Wales whilst at Cambridge bought an Isherwood seascape.
He lived in Wigan with his mother Lily, she encouraged and supported him and following her death in 1973 he became totally depressed. From this time he fought a constant battle with alcohol and finally died in a poverty of his own making.
