Pioneering physician and chemist who discovered the properties of carbon dioxide and developed the theory of latent heat, making significant contributions to the fields of chemistry and medicine.
William Cullen, a Scottish physician, chemist, and agriculturalist, is best known for inventing the basis of modern refrigeration and playing a central role in the Scottish Enlightenment. Born on April 15, 1710, Cullen's contributions to the fields of medicine, chemistry, and agriculture had a lasting impact on the 18th century and beyond.
Cullen studied medicine at the University of Edinburgh and later earned his MD from the University of Glasgow in 1739. He became a professor at the Edinburgh Medical School, where he taught and mentored many influential figures, including Benjamin Rush, John Morgan, and William Withering.
Cullen's medical textbooks, written primarily for his students, became popular in Europe and the American colonies. His most renowned work, First Lines of the Practice of Physic, was published in several editions between 1777 and 1784. In chemistry, Cullen's experiments on cooling and refrigeration led to the invention of the first artificial refrigeration system.
Cullen's pioneering work on refrigeration paved the way for significant advances in food preservation, transportation, and storage. His discoveries also led to improvements in the manufacturing of ice and the development of refrigeration systems for industrial and commercial use.
Cullen held prominent positions in various royal colleges and societies. He served as President of the Royal College of Physicians and Surgeons of Glasgow (1746-1747), President of the Royal College of Physicians of Edinburgh (1773-1775), and First Physician to the King in Scotland (1773-1790).

This esteemed organization brought together prominent thinkers and intellectuals, fostering collaboration and innovation in various fields.
William Cullen's teachings and mentorship inspired a generation of influential figures who went on to shape the fields of medicine, chemistry, and agriculture. His contributions to refrigeration and the Scottish Enlightenment continue to have a lasting impact on modern society.
Through his remarkable contributions to medicine, chemistry, and the Scottish Enlightenment, William Cullen left an indelible mark on the 18th century and beyond.
