(B. 6th May, 1791, Pozsony – D. 12th March, 1849, Pest)

Dean: 1826/27 – 1829/30

After completing his grammar school studies, he became assistant chemist in the Pharmacy of the Brothers of Mercy at the age of 15. He enrolled in a pharmaceutical course of Pest University and received a certificate of master pharmacist in 1810. Between 1812 and 1819 he pursued his studies in philosophy and medicine at Pest University, where, apart from being a student, he also worked as an assistant lecturer at the Department of Chemistry and Botany from 1815 under the guidance of Pál Kitaibel and János Schuster, respectively. In1820 he was conferred the degree of doctor of medicine and at the same time he was given the job of an assistant custodian at the Natural Collection of the National Museum and from 2nd September, 1821, he was given the full position of a custodian. In1832 he was appointed first a locum teacher, then, from 1834, professor ordinarius of botany. He taught this subject until 1848. In the meantime, between 1838/39-1841/42 he taught chemistry as well, as a locum professor teacher. At the same time he also fulfilled his responsibilities in the National Museum. During his botanical research trips he travelled all over the Carpathian Basin. His collection of herbarium sheets – containing more than 28,000 species – constitutes the basis of the herbarium of the Hungarian Museum of Natural Sciences. After the Revolution of 1848 he was among the first teachers who lectured in Hungarian language and he was the first one who used microscopic sections for demonstration. The compilation of the first Hungarian county flora (Flora comitatus Pestiensis, 1-2. 1825-26) is connected with his name. He also planned to make a summary of the flora of the whole country but he did not succeed in completing it. With his treatises on the pteridophytes and gramineae found in our country he started the compilation of taxonomic monographs. His achievements are mainly his organizing, teaching and popularising activities, and the establishment of the central herbarium and the publication of the exsiccates (collection of the Hungarian dried plants). In his lectures he adopted the progressive system of István Endlicher which continued to be in use for a long time even after his death.

He was founding member of the Natural Science Society (1841), and he was also elected member of several scientific associations (e.g. Imperial Society of Naturalists of Moscow, Society of Mineralogy of Weimar and Society of Botanists of Regensburg). As a sign of recognition several plants were named after him (e.g. Potentilla Sadleri Reichb, Ferula Sadleriana Ledeb). He filled the position of dean for four academic years from 1826/27.
