William Llewelyn "Buster" Lloyd-Jones (1914–1980) was a British veterinary practitioner. In his early years, he developed a passion for animals. Buster contracted polio as a young child, which affected him later in his life. As Buster grew up he was determined to become a vet. Though it meant a complete break with his father, he enrolled for training with a well-known animal society as a trainee in animal husbandry. Shortly afterwards he was appointed as lethalist to the animal dispensary at Wimbledon.
