Who were some people that had accomplishments or contributions on European thought from the 1300s to 1800s?

Explanation:

The period of European history extending from about 500 to 1400–1500 CE is traditionally known as the Middle Ages. The term was first used by 15th-century scholars to designate the period between their own time and the fall of the Western Roman Empire. The period is often considered to have its own internal divisions: either early and late or early, central or high, and late.
