Jan-Peter Frahm was a German bryologist whose research interests spanned the taxonomy, systematics, ecology, and conservation of bryophytes. He was born on February 14, 1945, in Hamburg, Germany, and died on February 5, 2014, in Belgium, at the age of 68. He studied biology and geography at the universities of Hamburg and Kiel and earned his Ph.D. in botany from the University of Kiel in 1972.
After completing his doctorate, he worked at the University of Duisburg, where he was appointed professor in 1981. He then continued his career at the University of Bonn, where he served as a professor of botany. His official retirement in 2010 was marked by a special issue of *Tropical Bryology*, Volume 31, featuring contributions from several of his colleagues and former students.
His scientific work covered a broad range of bryological disciplines. He made significant contributions to the taxonomy and systematics of mosses, particularly the Dicranaceae and the genus Campylopus. His major taxonomic publications included Afrikanische Campylopus-Arten (1985) and the treatment of Campylopodioideae and Paraleucobryoideae for Flora Neotropica (1991). He also investigated the ecology and biogeography of bryophytes, including their altitudinal distribution in tropical forests, and developed research on the use of bryophytes and lichens as bioindicators of atmospheric pollution and environmental change.
Beyond his scientific publications, Frahm played an important role in the dissemination of bryological knowledge. In 1989, he founded the journal Tropical Bryology with S. Robbert Gradstein and served as its Managing Editor until 2006. He also established several other bryological publications, including Bryologische Rundbriefe, Limprichtia and the Archive for Bryology. He was an early advocate of electronic publishing as a means of facilitating access to bryological research. Following his death in 2014, Uwe Schwarz founded Frahmia – A Bryological Online Journal in his memory, continuing Frahm’s commitment to making bryological knowledge widely accessible. The journal was conceived as a successor to the Archive for Bryology.
Jan-Peter Frahm was also the author of several books, including Moosflora (with W. Frey, 1983), Lexikon deutscher Bryologen (1995), Moose als Bioindikatoren (1998) and Biologie der Moose (2001). His botanical interests extended to field exploration, particularly in tropical regions and the Vosges Mountains in France, where he conducted numerous bryological excursions.
In recognition of his contributions to bryology, he received the Richard Spruce Award from the International Association of Bryologists in 1995.
Jan-Peter Frahm left a substantial scientific and editorial legacy, reflected in his numerous publications, his contributions to bryophyte systematics and ecology, and his efforts to make bryological knowledge more widely accessible.
