He was the youngest son of John and Hannah Clark of Chipping Norton,[1] and was educated at the Quaker school of Thomas Huntley at Burford in Oxfordshire.
[2] He was one of the first students enrolled at the newly established Veterinary College of London,[3] and studied under Charles Benoît Vial de Sainbel.
[4] Sainbel died of unidentified fever in 1793 (later thought to be glanders); Clark disregarded the instructions to stay clear of the body, to produce a death mask.
[5] Clark made a continental tour around 1797, but wartime conditions meant he wasn't able to visit France.
In his work on the hoof Clark concluded that great damage was done by the shoeing practices of the time, but his views were ridiculed by his contemporaries.
