[edit] Early life

Callister was born in Chute, near Ballarat in the Australian state of Victoria in 1893. The son of a teacher and post master and one of nine children, he attended the Ballarat School of Mines[1] and later won a scholarship to the University of Melbourne.[2]. He gained a Bachelor of Science degree in 1914 and a Master of Science degree in 1917.[3] In early 1915, Callister was employed by food manufacturer Lewis & Whitty, but later that year he enlisted in the Australian Imperial Force. However, he was soon withdrawn from active service and assigned to the Munitions Branch, working on explosives manufacturing in Britain.[4]. Following the end of World War I, he returned to Australia and resumed employment with Lewis & Whitty in 1919.

[edit] The invention of Vegemite

In the early 1920's, Callister was employed by Fred Walker and given the task of developing a yeast extract, as imports from the United Kingdom of Marmite had been disrupted in the aftermath of World War I. He experimented on spent brewer's yeast and independently developed what would later be called Vegemite, a product first sold by Fred Walker & Co in 1923.

Working from the details of a James L. Kraft patent, Callister was successful in producing processed cheese. The Walker Company negotiated a deal for the rights to manufacture the product, and in 1926, the Kraft Walker Cheese Company Ltd was established. Callister was appointed chief scientist and production superintendent of the new company.[4]

[edit] Later life

Callister got his Doctorate from the University of Melbourne in 1931, with his submission largely based on his work in developing Vegemite.[5]

He was a prominent member of the Royal Australian Chemical Institute, helping it to get a Royal Charter in 1931.[1]

Callister died in 1949, following a heart attack and is buried in Box Hill cemetery.
