Recorde, Robert (c.1510–1558)

Robert Recorde was a Welsh physician and mathematician, born in Tenby, Pembrokeshire, and trained at Oxford and Cambridge, who held various positions, including master of the mint in Bristol and later in Ireland, and wrote a number of influential math textbooks. These books formed a complete course and were written in English, rather than the usual Latin or Greek, so that they could be read anyone. In one of them Recorde introduces the "=" sign for "equals."
