Etymology of Erasmus

What does the name Erasmus mean?

The surname Erasmus is a patronymic name derived from the German personal name Erasmus (which in turn was derived from the Latinized form of the Greek word "erasmos," meaning love), borne by an early Christian saint. 1 Generally, many of the family evolved the name to Rasmussen in Denmark. The suffix '-sen' is translatable as 'son of.'

Erasmus is a notable forename that dates back to Erasmus of Formia, also known as Saint Elmo (died c. 303), a Christian saint and martyr. This saint gave rise to the forename in the fifteenth and sixteenth centuries including: Erasmus of Lueg, the 15th century renowned robber baron; Erasmus Grasser (c. 1450-c. 1515), the German master builder and sculptor; Erasmus Reinhold (1511-1553), the German astronomer and mathematician; Erasmus Finx (1627-1694), also known as Erasmus Francisci, the German polymath, author, and writer; and later in England, Erasmus Darwin (1731-1802), English physician and poet, grandfather of Charles Darwin.

Early Origins of the Erasmus family

The surname Erasmus was first found in Denmark where surnames were generally not adopted by the general population until the nineteenth century. In 1828 the Danish government ordered that children at baptism be given a "family name" along with a "first name". A second law (1860) made the family name hereditary.
