Academician N.I. Vavilov had an international reputation as a scientist, agronomist, botanist, geneticist, plant breeder, explorer for wild progenitors of cultivated plants, selector of new crop varieties, organizer of expeditions, administrator of a large research institute, and a statesman. Beginning in 1916 in collection of crop varieties in Iran and the Pamirs, he personally explored large segments of the earth. In 1926 he published his famous study on centers of origin of cultivated plants. While head of the Institute of Applied Botany and New Crops, he organized many expeditions to search for new varieties of crops and their wild ancestors and established an international collection of seeds. While President of the Geographical Society (1931-1940) he arranged to have the society transferred from the People's Commissariat of Education of the RSFSR to the Academy of Sciences of the USSR, thus transforming it from the Russian to the All-Union Geographical Society. He presented many lectures to the Society and greatly expanded its program of public lectures. But while on a scientific expedition to the western Ukraine, he was arrested on August 6, 1940. “An unforgiveable crime was committed. There has hardly been a more tragic fate since Galilee: the man who sought to give bread to the people died of starvation… He was a hero who gave his life for his scientific beliefs” (translated by H. L. Haslett, Birmingham, United Kingdom). 相似文献
