Adelard of Bath

Adelard of Bath (Latin: Adelardus Bathensis) (c. 1080 – c. 1152) was a 12th-century English natural philosopher. He is known both for his original works and for translating many important Greek and Arab scientific works of astrology, astronomy, philosophy and mathematics into Latin from Arabic versions, which were then introduced to Western Europe. He is known as one of the first to introduce the Hindu–Arabic numeral system to Europe. He stands at the convergence of three intellectual schools: the traditional learning of French schools, the Greek culture of Southern Italy, and the Arabic science of the East.
