His real name was Johannes or Johann Müller, but in publications he named himself after the canton of Aargau (his homeland) with the addition Argoviensis. This was suggested to him first to distinguish between botanists of the same name Carl Friedrich Philipp von Martius , to whose flora Brasiliensis Müller contributed.

Live and act

Müller Argoviensis, who came from a family of farmers, attended high school in Reinach AG and the industrial school in Aargau . With the support of Hans Schinz , Müller set up a private herbarium and when he continued his studies in Geneva in 1850, through the mediation of Theodor Zschokke, he came into contact with important botanists such as Alphonse Pyrame de Candolle , where he became the curator of his herbarium and worked as such until 1874 was. During this time he was an important collaborator for Candolle and his work on plant systematics , the Prodromus systematis regni vegetalis . He was also the curator of the herbarium of Edmond Boissier .

Müller was from 1868 private lecturer in Geneva and from 1871 extraordinary professor for medical botany in Geneva. From 1876 until his resignation for health reasons in 1889, he was a full professor of systematic botany in Geneva.
