Francesco (Frank) Veglia qualified as a veterinarian (Dr Med Vet) in Turin, Italy, in 1904 and came to South Africa in December 1911 to join the staff of the Veterinary Research Institute at Onderstepoort as a government veterinary research officer. He was the institute's first helminthologist, though L. Gough* had done some work on tapeworms in sheep and antelopes during the previous few years. During World War I (1914-1918) Veglia served in the Italian army but in 1917 returned to Onderstepoort to resume his research on economically important endo-parasites of mainly sheep. He is best known for his pioneering studies on the anatomy and development of wire worm (Haemonchus contortus) in sheep and was responsible for the development of the first effective remedy against wire worms. This "Onderstepoort wire worm remedy" remained in use for many years. Among others he published papers on "Oesophagostomiasis in sheep (preliminary note)" in the 13th and 14th Report of the Director of Veterinary Education and Research (1928, Part 2, pp. 755-801) and "The oviposition of some Strongylidae: Laboratory observations and practical deductions" in the South African Journal of Science (1926, Vol. 23, pp. 713-716).
Veglia became a foundation member of the South African Biological Society in 1916. He returned to Italy at the end of May 1927, where he was associated with the University of Turin and purchased the Burdizzo Instrument Company in Turin. He appears to have been still active on his wine farm in Italy around 1960.
