Kellner, Oskar

Born May 13, 1851, in Tillowitz (Silesia); died Sep. 22, 1911, in Karlsruhe, Germany. German agrochem-ist and physiologist.

Kellner graduated from the University of Leipzig in 1874. From 1874 to 1880 he was an assistant at the agricultural academies in Proskau and Württemberg, where he did research on the biochemistry of animals and plants. From 1880 to 1892, while a professor of agrochemistry at the University of Tokyo, he showed that carbohydrates could be converted to fat in animals. From 1892, Kellner headed the agricultural experimental station in Möckern. He developed a method for evaluating the nutritive value of various fodders according to their productive effect (in starch equivalents), which he described in The Feeding of Farm Animals (1905). Kellner was an honorary professor at the University of Tokyo. The Kellner Institute of Animal Husbandry in the German Democratic Republic was named after him.
