Carl Hagenbeck

Carl Hagenbeck (10 June 1844 – 14 April 1913) was a German merchant of wild animals who supplied many European zoos, as well as P. T. Barnum. He created the modern zoo with animal enclosures without bars that were closer to their natural habitat. He was also an ethnography showman and a pioneer in displaying humans next to animals in human zoos. His use of human zoos is widely considered to be inhumane today, and was controversial even at the time. The transformation of the zoo architecture initiated by him is known as the Hagenbeck revolution. Hagenbeck founded Germany's most successful privately owned zoo, the Tierpark Hagenbeck, which moved to its present location in Hamburg's Stellingen district in 1907.
