Carl Immanuel Gerhardt , mostly cited as CI Gerhardt, (* December 2, 1816 in Herzberg near Torgau , † May 5, 1899 in Halle an der Saale ) was a German mathematician and mathematician.

Gerhardt studied mathematics in Berlin from 1834 and received his doctorate there at the end of 1837 (with a thesis on the various reasons for calculus, which received the university award). At the same time he made his teacher examination. In 1838 he represented the mathematics teacher at the grammar school in Eutin and in 1839 became a grammar school teacher in Salzwedel . From 1853 to 1855 he was a mathematics teacher at the French high school in Berlin and at the artillery and engineering school. In 1855/6 he received leave (and a scholarship) for a scientific trip to Lausanne , Paris and Milan . From 1856 he was a teacher at the high school in Eisleben , where he became rector in 1876 and stayed until his retirement in 1891. He then lived in Halle and, after his wife died, with his daughter in Mainz and Graudenz, and from 1897 back in Halle.

Gerhardt is known for his research on Leibniz and as the editor of his mathematical (and later also philosophical) works from 1849. For this purpose, he viewed Leibniz's handwritten estate in Hanover . In 1877 he also wrote a history of mathematics in Germany, in which Moritz Cantor criticized an overly one-sided national standpoint. Gerhardt also published Maximus Planudes 'arithmetic book and some of Pappos' works . In 1861 he was accepted as a corresponding member of the Prussian Academy of Sciences . In 1874 Gerhardt was elected a member of the Leopoldina .
