William Cullen FRS FRSE FRCPE (/ ˈ k ʌ l ən /; 15 April 1710 – 5 February 1790) was a Scottish physician, chemist and agriculturalist, and professor at the Edinburgh Medical School. [3]
1755 – William Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled, absorbing heat from the surrounding air. [4] 1756 – The first documented public demonstration of artificial refrigeration by William Cullen [5] 1782 – Antoine Lavoisier and Pierre-Simon Laplace invent the ice-calorimeter
The history of artificial refrigeration began when Scottish professor William Cullen designed a small refrigerating machine in 1755. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled, absorbing heat from the surrounding air. [13]
The refrigerator: William Cullen (1748) [166] The flush toilet: Alexander Cumming (1775) [167] The vacuum flask: Sir James Dewar (1847–1932) [168] The first distiller to triple distill Irish whiskey: [169] John Jameson (Whisky distiller) The piano footpedal: John Broadwood (1732–1812) [170] The first automated can-filling machine John West ...
1748 – William Cullen demonstrates the first artificial refrigeration in a public lecture at the University of Glasgow in Scotland. 1759 – John Harrison uses a bimetallic strip in his third marine chronometer (H3) to compensate for temperature-induced changes in the balance spring. This converts thermal expansion and contraction in two ...
In 1748, the first known artificial refrigeration was demonstrated by William Cullen at the University of Glasgow. [1] Mr. Cullen never used his discovery for any practical purposes. This may be the reason why the history of the icemakers begins with Oliver Evans, an American

Adsorption refrigeration was invented by Michael Faraday in 1821, even though the basis of artificial modern refrigeration dates back to 1748 with William Cullen's experiments. [1] Adsorption is sometimes referred to as solid sorption. [2] It is very similar to absorption refrigeration (note that the second letter is different).
