In 1979 Brian Castledine, President of the British Go Association, died, and a charitable trust was set up in his memory. The Trust aimed to help young go players by providing equipment and supporting attendance at tournaments.
In 1983 Susan Barnes died in a car accident in Zimbabwe where she was working at the time. To commemorate her memory, her partner, Nick Webber, set up a separate Trust, but with very similar aims to the Castledine Trust.
In 2001 the Trustees of the two Trusts decided that it would be administratively convenient to merge the two Trusts. This was done by setting up a third Trust (the Castledine-Barnes Trust), with aims which were compatible with both the Castledine and Susan Barnes Trusts; these two Trusts then donated all their assets to the New Trust, ceased soliciting donations and were effectively closed down.
Brian Castledine learnt to play Go when he was working at ICL in Reading during a "Gap" year in 1971/2. In Autumn 1972 he came to St. John's College, Cambridge as a 6 kyu; at Cambridge he became Secretary then President of the Cambridge University Go Society.
After graduating he went to do a PhD at Imperial College, and then took a post in Brighton. In 1978 he was elected President of the British Go Association, before dying in an accident in February 1979.
Susan Barnes was a stalwart member of the London and Epsom Go Clubs.
She died in Zimbabwe where she had been working as an engineering consultant for the Ministry of Construction, mainly on building hospitals.
During a visit to Hwange game reserve, about 150 km south of Victoria Falls, she was driving into town to collect a spare tyre when her car left the road and turned over several times. She was taken to hospital but died a few hours later. She was buried at Hwange cemetery.
