Remembering, 2. Igor Rostislavovich Shafarevich (born June 3, 1923) is a Russian mathematician who has contributed to algebraic number theory and algebraic geometry. He has written books and articles that criticize socialism, and was an important dissident during the Soviet regime. 3. Charles Richard Drew (June 3, 1904 – April 1, 1950) was an American physician, surgeon, and medical researcher. He researched in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge to developing large-scale blood banks early in World War II. This allowed medics to save thousands of lives of the Allied forces. The research and development aspect of his blood storage work is disputed. As the most prominent African-American in the field, Drew protested against the practice of racial segregation in the donation of blood, as it lacked scientific foundation, an action which cost him his job. 4. Georg von Békésy (3 June 1899 – 13 June 1972) was a Hungarian biophysicist born in Budapest, Hungary. In 1961, he was awarded the Nobel Prize in Physiology or Medicine for his research on the function of the cochlea in the mammalian hearing organ. Békésy developed a method for dissecting the inner ear of human cadavers while leaving the cochlea partly intact. By using strobe photography and silver flakes as a marker, he was able to observe that the basilar membrane moves like a surface wave when stimulated by sound. Because of the structure of the cochlea and the basilar membrane, different frequencies of sound cause the maximum amplitudes of the waves to occur at different places on the basilar membrane along the coil of the cochlea. High frequencies cause more vibration at the base of the cochlea while low frequencies create more vibration at the apex. He concluded that his observations showed how different sound wave frequencies are locally dispersed before exciting different nerve fibers that lead from the cochlea to the brain. He theorized that the placement of each sensory cell (hair cell) along the coil of the cochlea corresponds to a specific frequency of sound (the so-called tonotopy). Békésy later developed a mechanical model of the cochlea, which confirmed the concept of frequency dispersion by the basilar membrane in the mammalian cochlea. But this model could not provide any information as to a possible function of this frequency dispersion in the process of hearing. 5. Raymond Pearl (3 June 1879– 17 November 1940) was an American biologist, regarded as one of the founders of biogerontology. He spent most of his career at Johns Hopkins University in Baltimore. Pearl was a prolific writer of academic books, papers and articles, as well as a committed populariser and communicator of science. At his death, 841 publications were listed against his name. Pearl maintained a loose interest in eugenics, but in 1927 published the landmark article The Biology of Superiority, which attacked the basic assumptions of eugenics. The article was the first general attack on eugenics by someone perceived as being within the movement. It also contributed to the emergence of reform eugenics and the population control movement. 6. Charles Waterton (June 3, 1782 – May 27, 1865) was an English naturalist and explorer. In 1804 he travelled to British Guiana to take charge of his uncles estates near Georgetown. In 1812, he started to explore the hinterland of Guiana, making four journeys between then and 1824, and reaching Brasil walking barefoot in the rainy season. He described his discoveries in his book Watertons Wanderings in South America[3] which inspired young British schoolboys like Charles Darwin and Alfred Russel. 7. Major General Henry Shrapnel (3 June 1761 – 13 March 1842) was a British Army officer whose name has entered the English language as the inventor of the shrapnel shell. 8. James Hutton FRSE (3 June 1726– 26 March 1797) was a Scottish geologist, physician, chemical manufacturer, naturalist, and experimental agriculturalist. He originated the theory of uniformitarianism—a fundamental principle of geology—which explains the features of the Earth’s crust by means of natural processes over geologic time. Huttons work established geology as a proper science, and thus he is often referred to as the Father of Modern Geology. Through observation and carefully reasoned geological arguments, Hutton came to believe that the Earth was perpetually being formed; he recognized that the history of the Earth could be determined by understanding how processes such as erosion and sedimentation work in the present day. His theories of geology and geologic time, also called deep time, came to be included in theories which were called plutonism and uniformitarianism. Some of his writings anticipated the Gaia hypothesis. 9. Giovanni Antonio Scopoli (3 June 1723—8 May 1788) was a Tyrolean physician and naturalist. His biographer Otto Guglia named him the first anational European and the Linnaeus of the Austrian Empire. 10. David Gregory (3June 1659– 10 October 1708) was a Scottish mathematician and astronomer. He was professor of mathematics at the University of Edinburgh, Savilian Professor of Astronomy at the University of Oxford, and a commentator on Isaac Newtons Principia.
