🏴🇬🇧 The man who invented the equals sign died in a debtors' prison. 🏴🇬🇧
2 small lines. You have drawn them all your life. A Welshman drew them first.
Robert Recorde was born in Tenby around 1512, a merchant's son. Oxford made him a fellow, Cambridge a doctor of medicine. But learning lived in Latin, locked away from people like his.
✍️ So he wrote his mathematics in plain English, as a friendly talk between a master and his pupil. The Ground of Artes, 1543. Arithmetic for anyone. Sailors learned from it. Shopkeepers. Merchants' clerks. Britain kept it in print for over 150 years.
The crown noticed and gave him the royal mint at Bristol. Then, in 1549, a powerful soldier came demanding the king's money for his army: Sir William Herbert. Recorde asked for the king's warrant. None came. So the mathematician refused the soldier.
⚔️ Herbert called it treason. Recorde spent 60 days under guard. He was released. The grudge was not.
The crown sent him to Ireland to run its silver mines. The mines failed and he came home unpaid. And the soldier he had refused was now the Earl of Pembroke. In 1556, Recorde accused the earl of misconduct at the crown's mints. True or not, it was a fight a scholar could not win.
⚖️ Pembroke sued him for libel. The court awarded the earl £1,000, money Recorde did not have.
And with ruin hanging over him, he wrote one last book. The Whetstone of Witte, 1557, the first English book of algebra. Page after page, he tired of writing the words "is equalle to". So he drew 2 parallel lines instead, "bicause noe 2 thynges, can be moare equalle."
🔥 The equals sign. Born on a page in 1557.
Within months, they came for him. The King's Bench prison, Southwark. A gaol for debtors. He died there in 1558. The crown itself still owed him £1,000 for Ireland. It paid the debt 12 years after his death.
🏛️ The earl got his verdict. The Welshman got every equation on Earth.
