The Cold Is British. They Just Never Told You 🇬🇧❄️

🏴󠁧󠁢󠁳󠁣󠁴󠁿🇬🇧 The machine is American, and Willis Carrier earned every bit of his name. But the cold inside it was first made in Britain, almost 150 years before his machine. In 1756, in a warm room in Edinburgh, the Scottish physician William Cullen drew the air from a glass of ether until it boiled cold, drank the heat from the water around it, and froze a film of ice by hand. Until then, cold was something you fetched from a mountain, a cellar or a hard winter. Cullen made it from nothing, the first ever to do so. Then he wrote it down and walked away. No machine, no patent, no fortune. Every fridge and freezer since runs on what he showed. The proof sat unused for the better part of a century. A London bench built the first working machine, and a Scot, James Harrison, carried mechanical refrigeration to Australia, where it froze meat and cooled beer. But cooling the air was only half of it. To wash, warm, cool and move the air all at once took another Scot, David Boswell Reid. When the old Houses of Parliament burned down in 1834, Reid designed a system that drew air in low, washed it through curtains of water, warmed it, cooled it over ice and drove it up through the towers. The gothic spires were its lungs. His fullest version went into St George's Hall in Liverpool in 1851, often called the world's first air-conditioned building, half a century before the machine that would replace it. It should have made him. Instead Reid clashed with the palace architect Charles Barry, his grand design was cut down, and in 1852 he was dismissed. He sailed for America and died in Washington in 1863, before the world was ready for him. 40 years later, in a Brooklyn printworks where damp air was ruining the colour, Willis Carrier built the machine that finished the story and became the father of modern air conditioning. The cold was British. The dream of conditioned air was British. The machine was American. That is no theft. That is what an inheritance is for. 📅 KEY DATES • 1756 — William Cullen demonstrates artificial refrigeration in Edinburgh • 1834 — a London bench (Jacob Perkins) patents the first working vapour-compression machine; the Houses of Parliament burn down • 1850s — James Harrison builds refrigeration in Australia • 1851 — St George's Hall, Liverpool, first operated, often called the first air-conditioned building • 1852 — David Boswell Reid dismissed from the Palace of Westminster • 1863 — Reid dies in Washington • 1902 — Willis Carrier designs his humidity-control system in Brooklyn 🇬🇧 WE ARE THE HOME OF BRITISH HEROES Proud Of Us tells the British history the textbooks leave out, across all four nations and across deep time.
