Desiderius Erasmus Roterodamus (sometimes known as Desiderius Erasmus of Rotterdam) (October 27, 1466/1469, Rotterdam – July 12, 1536, Basel) was a Dutch Renaissance humanist and a Catholic Christian theologian.
His scholarly name Desiderius Erasmus Roterodamus comprises the following three elements:
- the Latin noun desiderium ("longing" or "desire") the name being a genuine Late Latin name);
- the Greek adjective ἐράσμιος (erásmios) meaning "desired", and, in the form Erasmus, also the name of a saint;
- and the Latinized adjectival form for the city of Rotterdam (Roterodamus = "of Rotterdam").
