Henry Billingsley
Sir Henry Billingsley was born in about 1535 and died in 1606. He went to university in Cambridge and Oxford. At Oxford his maths teacher was a monk called Friar Whiteside. Billingsley became Lord Mayor of London in 1596 and was also a Member of Parliament from 1603 to 1604. In London he made his fortune as a haberdasher (someone who sells fabric and materials for sewing). However, he is most famous because he was the first person to translate Euclid's Elements of Geometry into English. He did this in 1570. One of the reasons he translated Euclid's book was probably because he thought that the maths that was in it would be very useful for merchants to know.
