German biologist and botanist (1839–1900).
Albert Bernhard Frank (17 January 1839 – 27 September 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. T
