Around 1861 he entered the University of Jena, where Ernst Abbe became the first of two physicists who decisively influenced his career (Weiss 1912, pp. 44–45).

Returning to physics, Abbe found in Weber a young and dynamic scientist, one who successfully focused much of his research efforts on re-thinking optical theory.

Abbe not only instructed Weber in the lecture hall and laboratory, he also served as a role model for him in several other ways: through his emphasis on the importance of laboratory work in general and precision instrumentation in particular; through his view that science should be closely related to practical life; and through his embodiment of the idea that a single individual could accomplish much in life.

For nearly thirty years Weber’s empirical findings remained an anomaly until one of his students presented a new explanation (Weiss 1912, pp.

The couple had three daughters and five sons, all of which became academics: Oskar: chemist; Friedrich: geologist; Ernst: civil engineer and astronomer; Helmut and Richard: physicians.
