19th-century German Protestant theologians

Albert Schwegler (10 February 1819 – 5 January 1857) was a German philosopher and Protestant theologian.

Eduard Gottlob Zeller (German: [ˈtsɛlɐ]; 22 January 1814, Kleinbottwar – 19 March 1908, Stuttgart) was a German philosopher and Protestant theologian of the Tübingen School of theology. He was well known for his writings on Ancient Greek philosophy, especially Pre-Socratic Philosophy, and most of all for his celebrated, multi-volume historical treatise The Philosophy of Greeks in their Historical Development (1844–52). Zeller was also a central figure in the revival of neo-Kantianism.
