Who invented vegemite?!
Answers: When, where, and why... and why is it called vegemite?
In 1922, Fred Walker (1884-1935) of Melbourne, Australia decided to try to make a special "yeast extract" that would be as delicious as it was nourishing for his Fred Walker Cheese Company to sell. The chief scientist in the company Fred owned was Dr. Cyril P. Callister, and it was Dr. Callister who invented the first Vegemite spread. He used brewer's yeast and blended the yeast extract with ingredients like celery, onion, salt, and a few secret ingredients to make this paste.
