On this day in history, 18th June 1558, the will of Robert Recorde, the Welsh mathematician, physician and mint administrator, was proved. His date of death is not known, but is thought to have been mid-June 1558.

Robert Recorde was born c.1512 and was the second son of Thomas Recorde of Tenby, Pembrokeshire, Wales, and his wife, Rose. Recorde graduated BA from Oxford in 1531 and, in the same year, became a fellow at All Souls College, Oxford. He is thought to have taught Mathematics before studying medicine at Cambridge, where he received his MD in 1545. He wroteThe Urinal of Physick, a urological treatise, and had it published by Reynolde Wolfe in 1547. He also wrote a book on anatomy.
