Mathematician:Gerard of Cremona

Mathematician
Italian scholar whose calling was to translate Arabic scientific and mathematical papers into Latin, many of which themselves were translations of works originally written in Greek.

His most immediate legacy was his use of the word sine (as sinus, meaning bay or fold) for the word that in the original Indian meant bow or chord.

His name is sometimes rendered Gherard or Gerhard.
