Poet, artist, filmmaker, author of the collage history, 'Pandaemonium 1660-1886: the Coming of the Machine as Seen by Contemporary Observers', and co-founder of the Mass Observation movement, 60 years before Google – Jennings has been referred to as the poet of English cinema for his evocative films of the Second World War.
