Rowland Emett is one of my favourite Punch illustrators, so a little bit about him ...
Perhaps not surprisingly, he was the son of an amateur inventor. He made his first contribution to Punch in 1939.
He was a draughtsman involved in the development of jet engines during World War II and later designed a railway for the Festival of Britain Battersea Pleasure Gardens. This brought him world-wide fame. He also built models for the film Chitty Chitty Bang Bang.
Among his inventions are a Forget-me-not Computer and the Exploratory Moon-Probe Lunacycle.
He died in 1990.
