Walther Otto Müller
Walther Otto Müller, also Otto Müller, (20 June 1833 – 17 July 1887, in Gera) was a German botanist and gardner.
Müller was the author of some books and several articles in scientific and botanical journals.
He collected plants, lichen and mosses for herbaria to sell the exsiccates as loose-leaf-collections.
The topography of the Gera region provided flora and fauna from lowland and highland at one rich spot.
