Julius Theodor Christian Ratzeburg was a German zoologist, botanist, entomologist, and forester.

Biography

Ratzeburg was born in Berlin, the son of a professor at the veterinary school of the University of Berlin. He studied medicine and natural sciences in Berlin and was primarily interested in botany. He became a private lecturer at the University of Berlin in 1828, when he was in contact with Alexander and Wilhelm von Humboldt. Two years later, he became professor of natural history there at the invitation of Friedrich Wilhelm Leopold Pfeil. He founded the botanic garden of forestry at Eberswalde, working there until his retirement in 1869. He returned to Berlin, where he resided until his death.
Ratzeburg was the author of important works on forestry and forest entomology, and is considered the founder of the latter discipline. He was notably interested in parasitic species. From 1827 to 1834, he wrote Medizinische Zoologie with Johann Friedrich von Brandt, which was a standard work for many years.
