Vandersyde was a British artist of remarkable talent whose work appeared in advertising and on prints that were widely distributed through Boots and Woolworths. One of his prints has gained a small measure of fame as it was briefly featured in the background of Stanley Kubrik's A Clockwork Orange. The picture, a portrait entitled 'Nina', was a commercial success, although Vandersyde is said to have had little business sense and sold the copyrights on many of his most commercially popular paintings for only a few pounds.
In 1918 he married Grace Collings in Hackney and had two children, Basil (b.1921) and Derek (b.1923). He was married a second time in 1942 to Dorothy Ellen Wood in Wandsworth and had two daughters, Wendy (b.1943) and Gillian (b.1947). The family lived at 4 Hepworth Road, Streatham, S.W.16, which is where Alfred died following a sudden heart attack on 10 November 1970.
