John Stanbury Steward (28 December 1906 – 18 September 1994) was an English biologist and veterinary scientist specialising in
Early life and education
Steward was born in
From 1921 to 1924, Steward attended Hereford Cathedral School, an independent boarding and day school. He attended the Royal Veterinary College from 1924 to 1928,[3] winning the Royal Agricultural Society's silver medal for Cattle Pathology, the Royal Veterinary Medical Association's gold medal, and the Centenary Prize.[4] He gained a diploma in Veterinary Medicine at the University of Edinburgh, which he attended from 1928 to 1929. In 1930, he enrolled at the Liverpool School of Tropical Medicine, University of Liverpool. That same year, he gained a Ministry of Agriculture Research Scholarship in Veterinary Pathology at the University of Cambridge.[5][1]
Career
Steward was a member of the Colonial Services Club, Cambridge.[1] He was elected a member of the Woolhope Naturalists' Field Club in 1954,[6] and from 1964 to 1965, was president of the Central Veterinary Society.[7]
While studying the infection of horses by
In 1933, Steward was successful in establishing that the worm Onchocerca cervicalis Railliet and Henry is transmitted by C. tuberculosis Mg., and probably by another species of Culicoides. This worm is the principal cause of fistulous withers and poll-evil in horses.[9][10]
1936 study of the life history of Brucella abortus by Steward revealed that adult forms of the parasite are common in the neck ligament, while embryos are found in the skin of this region. They develop in the midge's body in the course of about 24 to 25 days, and are then capable of infecting horses.[11]
As a member of the
In 1945, Steward recorded, for the first time in Great Britain, Malignant edema in swine likely due to Clostridium septicum.[13]
In 1951, Steward announced the preliminary results of his application of
Regarding human interactions, Steward proposed the marsh rice rat as a model organism in 1951 to study certain infections to which other rodents used at the time are not susceptible.[16] With Imperial Chemical Industries in 1952, he imported a dozen swamp rats from Florida to test the effectiveness of new drugs. They, he believed, would be more effective then the often used cotton rats "because they are considerably smaller".[17]
In 1955, Steward wrote four articles on Anthelmintic studies for the peer-reviewed scientific journal Parasitology. Each focused on a different approach to chemical testing.[18]
After leaving ICI Steward acquired a Veterinary practice in St James' Street Nottingham, where he practised as Evershed, Smythe & Steward. The premises in question, 68 St James' Street are listed as Grade II.
Steward resided in Gwynne House, Gwynne Street Hereford and later Inkersall Manor, Bilsthorpe.[19]
