Dr. Cyril P. Callister
Cyril Percy Callister (16 February 1893 – 5 October 1949) was an Australian chemist and food technologist who developed the Vegemite yeast spread. As well as Vegemite, he is known for his contributions towards processed cheese. Early life Cyril Percy Callister was born on 16 February 1893, in Chute, Victoria near Ballarat, son of Rosetta Anne (née Dixon) and William Hugh Callister, a teacher and postmaster. The second son of seven children, he attended the Ballarat School of Mines and Grenville College, and later won a scholarship to the University of Melbourne. He gained a Bachelor of Science degree in 1914 and a Master of Science degree in 1917. In early 1915, Callister was employed by food manufacturer Lewis & Whitty, but later that year he enlisted in the Australian Imperial Force. After 53 days, however, he was withdrawn from active service on the order of the Minister for Defence and assigned to the Munitions Branch, making explosives in Britain due to his know ...

The National Archives of Australia (NAA), formerly known as the Commonwealth Archives Office and Australian Archives, is an Australian Government agency that serves as the national archives of the nation. It collects, preserves and encourages access to important Commonwealth government records. Established under and governed by the ''Archives Act 1983'', its main roles are "to collect and preserve Australia's most valuable government records and encourage their use by the public, and to promote good information management by Commonwealth government agencies, especially in meeting the challenges of the digital age". The NAA also develops exhibitions, publishes books and guides to the collection, and delivers educational programs. History After World War I the Commonwealth National Library (later National Library of Australia) was responsible for collecting Australian Government records. The library appointed its first archives officer in 1944. In March 1961 the Commonwealth A ...

Royal Australian Chemical Institute
The Royal Australian Chemical Institute (RACI) is both the qualifying body in Australia for professional chemists and a learned society promoting the science and practice of chemistry in all its branches. The RACI hosts conferences, seminars and workshops. It is the professional body for chemistry in Australia, with the ability to award the status of Chartered Chemist (CChem) to suitably qualified candidates. History The RACI was formed as the Australian Chemical Institute in Sydney in September 1917. The driving force was David Orme Masson, professor of chemistry at the University of Melbourne. It was incorporated under the Companies Act in New South Wales in 1923. It was given a royal charter in 1932, but it was not until a supplementary royal charter in 1953 that "Royal" was added to the title of the institute. It moved to Melbourne in 1934. It was incorporated in Victoria in 2000. Since 1993, the institute has had its office at 21 Vale Street, North Melbourne, VIC 3051, Aus ...

Processed Cheese
Processed cheese (also known as process cheese, cheese food, prepared cheese, cheese product, or plastic cheese) is a food product made from cheese and unfermented dairy ingredients mixed with emulsifiers. Additional ingredients, such as vegetable oils, salt, food coloring, or sugar may be included. As a result, many flavors, colors, and textures of processed cheese exist. Processed cheese typically contains around 50 to 60% traditional cheese. History Processed cheese was first developed in Switzerland in 1911, when Walter Gerber and Fritz Stettler, seeking a cheese with longer shelf life and influenced by cheese sauces such as those used in fondue, added sodium citrate to melted Emmentaler cheese and found that the emulsified cheese sauce could be re-cooled into a solid again. Shortly after, in 1916, Canadian-American businessman James L. Kraft applied for the first U.S. patent covering a new method of processing cheese, which halted the maturation process.

Brewer's Yeast
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 µm in diameter, although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are called ...

Marmite
Marmite ( ) is a British savoury food spread based on yeast extract, invented by the German scientist Justus von Liebig. It is made from by-products of beer brewing ( lees) and is produced by the British company Unilever. Marmite is a vegan source of B vitamins, including supplemental vitamin B12. A traditional method of use is to spread it very thinly on buttered toast. Marmite is a sticky, dark brown paste with a distinctive, salty, powerful flavour and heady aroma. This distinctive taste is represented in the marketing slogan: "Love it or hate it." Such is its prominence in British popular culture that Marmite is often used as a metaphor for something that is an acquired taste or polarises opinion. Marmite is commonly used as a flavouring, as it is particularly rich in umami due to its very high levels of glutamate (1960 mg/100g). The image on the jar shows a ''marmite'' (), a French term for a large, covered earthenware or metal cooking pot. Marmite was original ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland.

The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Yeast Extract
Yeast extracts consist of the cell contents of yeast without the cell walls; they are used as food additives or flavorings, or as nutrients for bacterial culture media. They are often used to create savory flavors and umami taste sensations, and can be found in a large variety of packaged food, including frozen meals, crackers, snack foods, gravy, stock and more. They are rich in B vitamins (but not B12). Yeast extracts and fermented foods contain glutamic acid (free glutamates), an amino acid which adds an umami flavor. Glutamic acid is found in meat, cheese, fungi (mushrooms and yeast), and vegetables—such as broccoli, and tomatoes. The heat-autolytic process to make yeast extract of the autolysate type was invented in the 19th century by Justus von Liebig. Yeast cells are heated until they rupture, then the cells' own digestive enzymes break their proteins down into simpler compounds (amino acids and peptides), a process called autolysis. The insoluble cell walls are the ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ...
