renners

Renner is a surname of German origin. The name derives from the old German word renner, meaning runner, and likely originated as an occupational name for a courier or messenger. In English-language discourse, the plural form Renners is used to refer to multiple people bearing the surname Renner.

Notable individuals with the surname include Karl Renner (1870–1950), an Austrian politician who served as Chancellor and later as the first President of Austria after World War II; and Jeremy Renner (born 1971), an American actor known for roles in the Avengers films and other projects.

In science, the surname is associated with the Renner–Teller effect, a vibronic coupling phenomenon in linear polyatomic molecules, named after Renner and Teller; this concept is widely discussed in spectroscopy and physical chemistry.

The Renner surname remains common in German-speaking regions and their diasporas. Variants and related surnames include Renners (the plural form when referring to multiple people with the name), Rennert, and Renard.
