Ludwig Redtenbacher

Ludwig Redtenbacher (June 10, 1814, in Kirchdorf an der Krems, Austria – February 8, 1876, in Vienna) was an Austrian medical doctor and entomologist mainly interested in beetles.

Life
Ludwig Redtenbacher was the brother of the chemist Josef Redtenbacher (1810–1870).

From 1833 to 1838, Ludwig Redtenbacher studied medicine at the University of Vienna, becoming a salaried trainee in 1840. In 1843, he earned his medical doctorate, afterwards working as an assistant with the entomological collection of the Hofnaturalienkabinett (from 1847). In 1851, he became a professor of zoology in Prague and, from 1860, he was director of the Vienna Natural History Museum.

Although Redtenbacher worked mainly on the beetles of Austria, his new approach to classification or, in German, "analytischen" was widely adopted. He is also significant for his work involving beetles collected on the voyage of the Novara, an Austrian frigate that went on a round-the-world scientific expedition between 1857 and 1859.

He also described many of the beetles collected by Ida Pfeiffer (1797-1858). He wrote the entomological portion of Joseph Russegger's Reisen in Europa, Asien und Afrika (Travels in Europe, Asia and Africa).

Honours
In 1848, Carl Eduard Hammerschmidt named comadia redtenbacheri, known as the caterpillar placed in bottles of mezcal, in honour of Ludwig Redtenbacher.

The Redtenbachergasse in the Viennese districts of Ottakring and Hernals was named in his honor in 1894.
