Eulers

Eulers is a surname, typically interpreted as the plural form of Euler or as a historical variant of the surname Euler. In modern English, the standard spelling for the family name is Euler, and Eulers is rarely used outside genealogical or biographical contexts referring to multiple people with that surname.

Leonhard Euler (1707–1783) is the best-known bearer of the name; a Swiss mathematician and physicist whose work laid foundations across analysis, number theory, geometry, and mechanics. The Euler name is historically associated with a Basel-based family involved in mathematics and science during the 18th century and beyond.

In mathematics and related fields, many concepts bear the Euler name, typically written as Euler's something, such as Euler's formula for complex exponentials, Euler's identity, Euler's method for numerical approximation, Euler equations in fluid dynamics, Euler angles for describing three-dimensional orientation, and the Euler characteristic in topology. The use of Euler's possessive form reflects attribution to Leonhard Euler and related family members, rather than to a separate entity called Eulers.
