Albert Bernhard Frank

Albert Bernhard Frank (January 17, 1839, Dresden – September 27, 1900, Berlin) was a German botanist, plant pathologist, and mycologist. He is credited with coining the term mycorrhiza in his 1885 paper "Ueber 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. 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.
