About us Who we are Our history Animal Free Research UK began as the Dr Hadwen Trust for Humane Research in 1970. Animal Free Research UK began in 1970 when the British Union for the Abolition of Vivisection (BUAV), now called Cruelty Free International, set up the Dr Hadwen Trust for Humane Research in honour of its former president, Dr Walter Hadwen. We are a grant-giving trust, set up to award grants to scientists to help replace the use of animals in medical research. We split from the BUAV in 1980 and became a charity in our own right. We became an incorporated charity in 2013 and in April 2017, we adopted the working name Animal Free Research UK.
