Julius Kollmann (24 February 1834, Holzheim am Forst – 24 June 1918, Basel) was a German anatomist, zoologist and anthropologist.
He studied at the universities of Munich and Berlin, then furthered his education in London and Paris.
[2] Known for his work in the fields of descriptive anatomy and histology, he eventually became associated with studies involving evolutionary theory, developmental history and anthropology.
In 1884 Kollmann introduced the term "neoteny" to define the transformation process where animals such as newts mature sexually while still in the larval form.
[3] As an anthropologist, he conducted analyses of prehistoric skulls found at Auvernier and Schweizersbild.
