Who invented marmite

Federation University Australia, 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 Mundell at Annau, on 8 March ; they had two sons and a daughter.

In February 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 de novo from brewers' yeast. Under the trademark Vegemite it was placed on the market early in 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 to persuade Kraft to grant a licence for the manufacture of Kraft cheese in Australia. So the Kraft Walker Cheese Co.

He was the key to the increasing technical emphasis of the company. In he had sent samples of Vegemite to London to be tested for Vitamin B activity—a far-sighted move in the very early days of vitamin knowledge. The result confirmed Callister's confidence in the product as a valuable nutrient. In he carried out detailed original studies on the scientific background of cheese-making to establish the parameters of good cheese quality.

Convinced that background science was essential in any industry, in he appointed a bacteriologist to his staff, possibly the first such appointment in Australia.
