In page Gottlob Frege:

"

Starting in 1871, Frege continued his studies in Göttingen, the leading university in mathematics in German-speaking territories, where he attended the lectures of Alfred Clebsch (1833–1872; analytic geometry), Ernst Christian Julius Schering (1824–1897; function theory), Wilhelm Eduard Weber (1804–1891; physical studies, applied physics),[1] Eduard Riecke (1845–1915; theory of electricity), and Hermann Lotze (1817–1881; philosophy of religion).[1] Many of the philosophical doctrines of the mature Frege have parallels in Lotze; it has been the subject of scholarly debate whether or not there was a direct influence on Frege's views arising from his attending Lotze's lectures.[citation needed]
