Henry Yevele
Henry Yevele (c. 1320–1400) was England's royal master mason from 1360 until his death, serving Edward III and Richard II. Probably born in Derbyshire, he may have learned the trade from his father, who may have been a mason; he refaced Westminster Hall at the Palace of Westminster and built the Bloody Tower at the Tower of London.
His greatest surviving works are the naves of Westminster Abbey, begun in 1362, and Canterbury Cathedral, built from 1377 in an early Perpendicular Gothic style and finished only in 1400. He died that year.
