Ludwig Ganglbauer (1 October 1856, in Vienna – 5 June 1912, in Rekawinkel, near Kaltenbach Lower Austria), was an Austrian entomologist who specialised in Coleoptera (i.e. beetles).
He subsequently took a job at the Wiener Hofmuseum (now the Vienna Museum of Natural History).
[1] He became director of the Department for Zoology at the Vienna Natural History Museum in 1906.
Ganglbauer wrote Die Käfer von Mitteleuropa (Beetles of Central Europe), 4 vols., 1892-1904 which was unfinished at his death, but is still widely read by entomologists.
