Bagpuss, Ivor The Engine, Noggin The Nog, The Clangers - hugely influential TV shows that shaped more than one generation of children. Oliver Postgate brought us all these characters, often in collaboration with model-maker Peter Firmin. He worked with both the BBC and ITV from the 1950s until the present day, and we composed one of our Time Machine features about him last year, celebrating those knitted, stop-motion alien mice, The Clangers (first broadcast in 1969). As Postgate voiced most of the productions himself, his distinctive voice has become familiar to millions. He died at his home in Broadstairs, aged 83.
