Albert Bernhard Frank

Albert Bernhard Frank (January 17, 1839 – September 27, 1900) was a German botanist, plant pathologist, and mycologist, born in Dresden. He is credited with coining the term ''mycorrhiza'' in his 1885 paper "Über die auf Wurzelsymbiose beruhende Ernährung gewisser Bäume durch unterirdische Pilze".

Frank was commissioned to develop practical methods for truffle cultivation by the King of Prussia (Wilhelm I). Although this project was not successful, it led to his elucidation of the nature and development of mycorrhizae. The history and impacts of Frank's work on mycorrhizae were reviewed by Trappe.

The bacterial genus ''Frankia'' and family ''Frankiaceae'' were named after him.

In 1877, Albert Frank coined the term "symbiosis" (German: Symbiose) to describe the nature of lichens. He died in Berlin.
