Peter Firmin - the man behind childhood favourites such as The Clangers, Bagpuss, Basil Brush and Ivor The Engine - has died at the age of 89.
Along with his co-creators, Mr Firmin brought joy to generations of children with his skilfully-crafted animated creations.
His spokesman, who confirmed he died at his Kent home today after a short illness, said: "During a career spanning over six decades, Peter worked with great skill in a remarkably wide variety of creative disciplines as a fine artist, craftsman and author.
"Of all his work, he will probably be most fondly remembered for the characters he co-created and made."
Firmin created the cheeky fox Basil Brush with Ivan Owen and worked with his long-time business partner Oliver Postgate on Bagpuss, The Clangers, Ivor the Engine, Noggin the Nog and Pogles Wood.
The spokesman for production company Coolabi added: "These were TV programmes with such magical and enduring appeal that they remain hugely popular to this day.
"In 1999 Bagpuss was voted the most popular BBC children's programme ever made, and in 2014 Peter received a Bafta Lifetime Achievement Award.
"Peter continued to work with great enthusiasm on creative projects right up until the beginning of 2018, most notably on a new series of Clangers, which won a Bafta in 2015.
"Peter leaves behind his wife Joan and his six daughters (who often collaborated on many of his works) as well as his many grandchildren and great grandchildren.
"We kindly ask for the family's privacy to be respected at this time."
