Question

In 1679, Denis Papin, a French physicist, who assisted Robert Boyle, used the latter's scientific discoveries and invented what is today one of the most commonly found kitchen equipment. His invention earned him a membership of the Royal Society of England. What was the invention?

• A. Knife
• B. Fork
• C. Pressure Cooker
• D. Stove

Hint:

His device used pressure and steam to cook food faster, the ancestor of a modern kitchen appliance.

Answer 1

The Correct Option is C

The correct answer is Pressure Cooker, not Fork as listed in the original answer key for this question. Denis Papin, working alongside Robert Boyle in London, built a sealed vessel in 1679 called the "steam digester." It used a tightly fitting lid and a safety valve to trap steam under pressure, raising the boiling point of water inside and allowing food and even bones to cook much faster and softer than in an open pot. This device is directly recognized as the ancestor of the modern pressure cooker and also laid the groundwork for the autoclave used in sterilization. Papin's invention impressed the Royal Society enough that he was elected a Fellow in 1680, exactly as the question describes.

Knife and Fork are everyday kitchen tools with histories going back to ancient civilizations, long before Papin was born, so neither has any link to his 1679 invention or his Royal Society membership. Stove is also incorrect since Papin did not invent any form of cooking stove; his contribution was the sealed pressure vessel, not a heat source. Given the well documented history of the steam digester and its role in Papin's Royal Society election, the factually accurate answer is Pressure Cooker, and the original key listing Fork appears to be an error.
