Catholic Church and health care the retinal image. Gregor Mendel, an Austrian scientist and Augustinian friar, began experimenting with peas around 1856. Mendel had joined the Brno Augustinian Monastery in 1843, but also trained as a scientist at the Olmutz Philosophical Institute and the University of Vienna. The Brno Monastery was a centre of scholarship, with an extensive library and tradition of scientific research. Observing the processes of pollination at his monastery in modern Czechoslovakia, Mendel studied and developed theories pertaining to the field of science now called genetics. Mendel published his results in 1866 in the "Journal of the Brno Natural History Society", and
Franz Unger of botany at the University of Graz and also taught at the Joanneum (which became the Universalmuseum Joanneum and the Graz University of Technology); in 1850 professor of plant physiology in Vienna. In 1852 he travelled to Northern Europe and to the Orient. Unger retired in 1866 and lived on his farm near Graz. Unger was one of the major contributors to the field of paleontology, later turning to plant physiology and phytotomy. He hypothesized that (then unknown) combinations of simple elements inside a plant cell determine plant heredity and greatly influenced the experiments of his student Gregor Johann Mendel.
