Known forcoining the term "mycorrhiza"

Albert Bernhard Frank (January 17, 1839 in Dresden - September 27, 1900 in Berlin) was a German botanist, plant pathologist, and mycologist. He is credited with coining the term mycorrhiza in his 1885 paper "Über die auf Wurzelsymbiose beruhende Ernährung gewisser Bäume durch unterirdische Pilze".[1][2]

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.[3]

The bacterial genus Frankia and family Frankiaceae were named after him.[4]

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