Riemanns

Riemanns is a German-language surname. In English usage, the phrase the Riemanns refers to multiple people bearing the surname Riemann, or to a family with that name. The base form Riemann is the standard singular surname, as in Bernhard Riemann.

The most famous bearer is Bernhard Riemann (1826–1866), a German mathematician whose work laid the foundations of analysis, differential geometry, and number theory. His key contributions include the Riemann integral, Riemann surfaces, and important conjectures such as the Riemann hypothesis. His ideas also influenced later developments in topology and mathematical physics.

In general, the surname Riemann appears in mathematical literature primarily through these contributions; the plural Riemanns would refer to multiple people or a family with that name, rather than to a mathematical object. The surname is found among German-speaking populations and in regions influenced by German emigration.
