Desiderius Erasmus, probably born in Rotterdam around 1466, became one of the most influential scholars of the European Renaissance. Educated in the Low Countries, he entered a monastery and was ordained a priest, but his deepest interests lay in classical languages, Scripture and education. He travelled widely, spending time in England and Italy, and corresponded with scholars and rulers throughout Europe.

In 1511 he published In Praise of Folly, a witty satire exposing the vanity, greed and hypocrisy of his age, including failings within the Church. In 1516 he issued a groundbreaking edition of the Greek New Testament alongside a new Latin translation. His scholarship encouraged readers to return to Christianity's original sources rather than rely unquestioningly on received interpretations.

Erasmus advocated learning, moderation and reform without a permanent break with Rome. Although his criticism helped prepare the ground for the Reformation, he remained a Catholic and resisted Martin Luther's increasingly uncompromising position. Their disagreement over free will developed into a major theological controversy. Erasmus died in Basel in 1536. His legacy is that of a humanist who challenged established authority while retaining his faith in education, thoughtful argument and the possibility of peaceful change.
