Johann Georg Heinrich Feder

Johann Georg Heinrich Feder, painting by Johann Heinrich Tischbein the Younger, c. 1772, Gleimhaus, Halberstadt. Johann Georg Heinrich Feder (; 15 May 1740 – 22 May 1821) was a German philosopher.

Life Feder was born on 15 May 1740 in the village of Schornweisach (now part of Uehlfeld, Bavaria) in the Principality of Bayreuth, the son of Martin Heinrich Feder (died 1749), the village pastor. Feder studied theology and pedagogy at the University of Erlangen. From 1768 to 1782 he was Professor of Philosophy at the University of Göttingen. At the time of his death, in Hanover, he was Director of the Pageninstitut (a courtly educational institution for pages).

His writings were widely read at the time due to their clear and tasteful mode of presentation. Feder decisively countered Immanuel Kant's idealism. He gained notoriety through his abbreviation of Christian Garve's review of Kant's Critique of Pure Reason. As philosopher Feder belonged to the better representatives of the eclectics tending towards the Leibniz–Wolff School.
