Friedrich Ueberweg

Helene was a daughter of Karl Theodor Boeddinghaus (21 February 1765 - 27 December 1842), who was a Lutheran pastor in the neighboring town of Ronsdorf.

He married Anna Henriette Luise Panzenhagen (24 August 1844 - 16 March 1909) on 1 September 1863, in Pillau, Province of Prussia.

[1] At first Ueberweg followed the empiricism of Friedrich Eduard Beneke (1798-1854), and strongly opposed the subjectivistic tendency of the Kantian system, maintaining in particular the objectivity of space and time, which involved him in a somewhat violent controversy.

Beneke and Friedrich Schleiermacher exercised most influence upon the development of his thought.

[1] Ueberweg's compendious Sketch of the History of Philosophy (3 vols., 1863–1866) is regarded by many academics and scholars as remarkable for its fullness of information, conciseness, accuracy and impartiality.
