John Patrick Walsh

Sir John Patrick Walsh was an Australian–New Zealand dental academic. Born in Australia, Walsh trained as a dental mechanic, and then completed degrees in dentistry and medicine at the University of Melbourne. He was appointed Dean of New Zealand's dental school at the University of Otago in 1946, where he oversaw the introduction of training in paediatric dentistry, orthodontics and public health dentistry. Walsh campaigned for improved facilities at the dental school and the new building, opened in 1961, was named in his honour in 2001. He is remembered for his development of a high-speed dental drill and a successful campaign for fluoridation of the public water supply.
