Louis Desliens, a veterinarian from Châtillon-sur-Seine, was a pioneer in equine medicine and veterinary science. He developed surgical techniques and conducted research on blood transfusions and pressure, leading to the invention of the Louis Desliens hemodynamometer, later commercialized by Splenger.
His grandson Michel Desliens, also a veterinarian, donated a large collection of instruments to the museum—reminding us that veterinary science first served working animals in agriculture and transport.
