Donald was an animal rights advocate who founded the Vegan Society in 1944. In the same year, Donald and his wife, Dorothy, coined the word 'vegan' from the first three and last two letters of 'vegetarian'. Donald described himself in this interview as agnostic, saying, "I've never been clever enough to be an atheist - an agnostic, yes." He died in 2005 at the age of 95.
