Julius Kühn

Julius Gotthelf Kühn was a German academic and agronomist and he was one of the pioneers of plant pathology. Kühn's father was a land owner and he gained experience in agriculture and botany on his father's land. He was trained in Bonn, starting at age 30 and was awarded his doctorate, which focused on diseases of beet and canola at Leipzig. In 1862, he became a professor of agriculture at the University of Halle. Kuhn published more than 70 papers on mycology and plant pathology over the course of his career.
Kühn collected and characterized precisely smut fungi with material distributed in famous exsiccatae edited by Felix von Thümen, Gottlob [Ludwig Rabenhorst] and Heinrich [Georg Winter]. An example is the exsiccata item no.2099: Ustilago rabenhorstiana in the series Rabenhorst, Fungi Europaei exsiccati.
One of his seminar papers was the 1858 publication "Die Krankheiten der Kulturgewächse".
He was honoured in 1898, when botanist Paul [Wilhelm Magnus] circumscribed Kuehneola, which is a genus of rust fungi in the family Phragmidiaceae.
