Margaret Thatcher worked as a food scientist, testing cakes and ice cream

From 1943 until 1947, Margaret Roberts attended Oxford University to study chemistry. Her first position was at Essex's BX Plastics. However, she was suggested as a potential parliamentary candidate to the Dartford Conservative Association by college friends. She traveled to London and accepted a new position with the food company J. Lyons & Co. in search of a more practical location from which to begin a campaign. Her job there focused on evaluating the quality of ice cream and cake fillings. She also looked into the chemical process of saponification, which is used to make soap.

She was a member of the group that developed a technique to boost the quantity of air injected into ice cream so that it could be produced more cheaply and with fewer ingredients. The innovation resulted in the creation of soft-serve ice cream, known as Mr. Whippy, and served from trucks throughout Great Britain. This is known as one of the most interesting facts about Margaret Thatcher.
