The National Museum of Computing needs your help. A painting is missing. That’s not that unusual but this one is of the Harwell Dekatron / WITCH.
The WITCH is a beautiful machine. She even has a face as I have seen her running at the museum a couple of times. It does make you smile and it would be nice to reunite her with her portrait to remind her of times that were not that happy
The huge painting Portrait of a Dead WITCH by John Yeadon may not be in the world’s top ten list of missing works of art, but it is one that is now eagerly sought by The National Museum of Computing on Bletchley Park.
The painting’s subject, the Harwell Dekatron / WITCH computer, is the world’s oldest working digital computer. The machine itself has had a charmed life surviving several threats to its existence until it was restored to rude health at TNMOC in 2012 to become one of the museum’s star attractions.
Today, the whereabouts of the 1983 Portrait of a Dead WITCH is unknown and the Museum and the artist are trying to locate it. It was last heard of in October 2014 when it was sold at auction in Lincoln to an unknown buyer for just £75! At seven feet high by nine feet wide, the acrylic painting is almost life-size and would be hard to miss!
The painting, like its subject, has had a chequered history. It was created by artist John Yeadon in 1983 because he was so fascinated by the then ‘dead’ machine in Birmingham’s Museum of Science and Industry: “It was a a diabolical contraption, a dusty hunk of electric and mechanical hardware that reminded me of the disturbing 1950s Quatermass science fiction television series that so impressed me as a child.
“But the computer was abandoned in a museum like an ancient relic. Vintage twentieth century technology doesn’t seem to fare as well as nineteenth century working steam engines with their polished brass pistons. I wanted to give this dead computer new life, but with menace and humour, so I approached the painting in in a playful, lively, anthropomorphic way and included an abacus and Babbage’s brain in a glass dome on a table in front of the computer.”
On completion, the painting was exhibited at Leicestershire Schools and Colleges Show in 1984 and then bought by Leicestershire Local Education Authority as part of the Leicestershire Artworks Collection. At some point it was loaned to Newbridge High School in Coalville, Leicestershire, but when it converted to Academy, the painting once in a public collection was auctioned off privately, much to the chagrin of its creator.
John Yeadon now wants to locate the painting for a retrospective exhibition when he reaches the age of 70 in two years’ time. He has contacted the auction house, but drawn a blank in finding the purchaser.
Kevin Murrell, a TNMOC trustee, whose initiative it was to bring the WITCH to the Museum for restoration in 2009, expressed the Museum’s interest: “We have been astonished that we have only just heard about the existence of the painting. We would love to see it and perhaps acquire it for the Museum as another artifact telling the story of this remarkable machine that has survived against all the odds. Paintings of computers are quite rare and this is especially significant in depicting one of the earliest computers.”
Today, the Harwell Dekatron / WITCH computer is in almost daily use and is an inspirational machine for the many groups of students that visit TNMOC for the Museum’s Learning Programme.
