Have
you heard of Dr Cyril P Callister?
Ok
maybe you have not heard of the man but if you're an Aussie you most
likely have eaten his creation which was Vegemite all Aussies pretty
much like Vegemite. Way back in 1922 the Fred Walker company hired a
young chemist to develop a spread from brewer's yeast,it was
labelled “Pure Vegetable Extract” which doesn't sound as good as
Vegemite, in my opinion.
The
Fred Walker company decided to have a national competition to come up
with a name for the product, unfortunately they didn't keep a record
of the winners name we do know that it was Fred Walker's daughter who
chose the winning name and that name was Vegemite.
Cyril
Percy Callister was a food technologist, who was born on 16 February
1893 at Chute near Beaufort, Victoria, son of William Hugh Callister,
schoolmaster and his wife Rosetta Anne, née Dixon.
He
was educated at state schools, Grenville College, Ballarat, and the
Ballarat School of Mines, he attended the University of Melbourne on
a major residential scholarship to Queen's College.
In
January 1915 he joined Lewis & Whitty, manufacturers of food and
household products. In June he enlisted in the Australian Imperial
Force. Within three months the Department of Defence withdrew him to
join the Munitions Branch. Shortly afterwards he was sent to Britain
and spent the war working on explosives manufacture in Wales, and in
Scotland where he met and married Katherine Hope they had two sons
and a daughter.
After
her return to Australia in 1919 he rejoined Lewis & Whitty where
he remained until that company was taken over. In February 1923 he
was appointed to Fred Walker's small food company to develop
yeast-extract for retail sale.
Although
this product was known overseas, no information was available about
the process, and Callister developed it from brewers' yeast. Under
the trademark Vegemite it was placed on the market early in 1924 and
slowly became an established item, solely through Callister's
technological skill and perseverance.
Walker
was also interested in methods for preserving cheese, and involved
Callister in this as well. Thus the chemist rapidly became well
informed in microbiology and began to experiment with
cheese-processing.
With
the help of patents held by the American James L. Kraft, he made a
satisfactory product and Walker used this in 1925 to persuade Kraft
to grant a licence for the manufacture of Kraft cheese in Australia.
So the Kraft Walker Cheese Co. was established in 1926 with Callister
as chief chemist and production superintendent.
