Born 22 july 1822 , died on january 6th 1884.
Even though I had to go through a number of bitter times in my life, I must thankfully own that the pleasant and the good prevailed. My scientific work brought me a great deal of satisfaction, and I am convinced that it will not be long before the whole world acknowledges it.

Diebl (1770-1859). From 1825 to 1849 Diebl taught agriculture and natural science at the Philosophical Institute in Brno,. From 1827 to 1832 he was Custodian of the Brno museum. He was a notable expert on agriculture and made a particularly significant contribution to the promotion of pomology. He was also appreciated as a plant-breeder. In his published papers he advocated the use of modern methods in agricultural production. He also described the technique of artificial fertilization, considering it the most important method in plant breeding. In the 1830s Diebl was associated with Napp as the secretary of the Pornological Society, taking part in the announcement of prize essays on the breeding of new plant varieties through artificial hybridization. In 1839 the gardener J. Tyrdc won a prize for breeding a new variety of currant-bush and describing the method applied. After his dead on january 6th 1884, the merits of the deceased abbot were appreciated in Brno. At the same time he was acknowledge as an important official in public institutions and scientific societies. Only the horticulturists recalled Mendel's epoch-making, experiments with plants hybridization. His scientific papers on plant hybrids remained , however, without recognition until the end of the century. In the 1880s A. Weismann was already showing the material of the nucleus to be the carrier of heredity. Thus he encourage other scientist to do research on heredity in connection with the structure and function of the chromosome. In 1900 attention was drawn to Mendel's work by Hugo de Vries in Holland and by C. Correns in Germany. To their voices was later added that of E. Tschermak of Vienna, who was the instigator of the application of Mendel's theory in plant breeding. In 1910 Tschermak founded in Lednice in Moravia a research institute for plant breeding called the Mendeleum. At the time E. Proskowetz in Kvasice and J. Vailha in Brno were elaborating modern methods of cereal breeding. After 1900 Mendel's Pisum paper was said to have been rediscovered, and began to be considered the basis of the study of the principles of heredity in plants, in animals and in Man. In 1906 Bateson called the teaching of heredity "genetics", and in 1909 W. johannsen named the unit of heredity the "gene". In 1910 a memorial was raised in Brno to Mendel, the building of which was supported by prominent researchers from abroad. The occasion of the centenary of Mendel's birth in 1922 was commemorated with an international scientific gathering in Brno.
In 1910 Morgan demonstrated the gene to be a part of the chromosome structure.

The anniversary of Gregor Mendel's birth reminds us and all scientists abroad to celebrate this day at the very place of the scholar's activity a duty to which all of us are bound in honour. Invitation to the Gregor Mendel Centenary, 1922.
