Recorde, Robert (c.1510–1558)
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."
