Ernst Otto Heinrich Kohlschütter (26 December 1837 – 7 September 1905) was a German physician born in Dresden. He was the father of astronomer Arnold Kohlschütter (1883–1969). The son of Dr. Otto Kohlschütter (1807–1853), he studied medicine at the University of Leipzig. In 1862 he earned his doctorate with an influential dissertation on "sleep depth" titled Messungen der Festigkeit des Schlafes. With help from Theodor Weber (1829–1914), he was able to remain in Leipzig as an assistant at the university polyclinic. Later on, he received his habilitation at the University of Halle, becoming a privat-docent of internal medicine and subsequently a lecturer in balneology . He participated in the Franco-Prussian War, being awarded the Kriegsdenkmünze für die Feldzüge 1870–71 for his efforts. In 1875, he became an associate professor at the University of Halle. Although he never attained the title of "full professor" during his career, he remained at Halle as a lecturer, and in the meantime, worked at a private medical practice and was devoted to many social and political concerns. He was involved in the creation of Volksküchen (soup kitchens) and Volkskaffeehallen (people's coffee halls), and along with political economist Johannes Conrad, he opened a popular reading room in Halle. In 1880 he founded a holiday camp at Güntersberge in the Harz Mountains for needy, financially disadvantaged children. In 1892 he was appointed councillor (Gemeinderat) in Halle. He died in 1905 at Bad Salzschlirf. The thoroughfare Kohlschütterstraße in Halle is named in his honor. Published works Messungen der Festigkeit des Schlafes, 1863.
