09 Apr 1919 J. Presper Eckert Jr.	science	birth J. Presper Eckert Jr. Born 9 Apr 1919; died 3 Jun 1995 at age 76. American engineer and inventor of the first general-purpose electronic computer, a digital machine that was the prototype for most computers in use today. In 1946, Eckert with John W. Mauchly fulfilled a government contract to build a digital computer to be used by the U.S. Army for military calculations. They named it ENIAC for Electronic Numerical Integrator and Computer. By 1949, they had started a manufacturing company for their BINAC computer. This was followed by a business oriented computer, UNIVAC (1951), which was put to many uses and spurred the growth of the computer industry. By 1966 Eckert held 85 patents, mostly for electronic inventions.

29 May 1919 Einstein's relativity theory proved	science	Einstein's relativity theory proved In 1919, a solar eclipse permitted observation of the bending of starlight passing through the sun's gravitational field, as predicted by Albert Einstein's theory of relativity. Separate expeditions of the Royal Astronomical Society travelled to Brazil and off the west coast of Africa. Both made measurements of the position of stars visible close to the sun during a solar eclipse. These observations showed that, indeed, the light of stars was bent as it passed through the gravitational field of the sun. This was a key prediction of Albert Einstein's theory that gravity affected energy as in addition to the familiar effect on matter. The verification of predictions of Einstein's theory, proved during the solar eclipse was a dramatic landmark scientific event.
29 May 1919 Einstein's	science	Einstein's (physics) Einstein's theory of general relativity is tested by Arthur Eddington's observation of the "bending of light" during the total solar eclipse on this day observed in Principe, and by Andrew Crommelin in Sobral, Ceará, Brazil (confirmed November 19).

15 Jul 1919 Emil Fischer	science	death Emil Fischer Died 15 Jul 1919 at age 66 (born 9 Oct 1852). German chemist who was awarded the Nobel Prize for Chemistry in 1902 in recognition of his investigations of the sugar and purine groups of substances. He determined the structures of uric acid, xanthine, caffeine, theobromine, and other related compounds, and showed they are all derivatives of a single compound, a nitrogenous base that he named purine. His study of sugars led him to investigate the reactions and substances involved in fermentation, leading to his investigations of how enzymes break down sugars. Thus, Fischer laid the foundations for enzyme chemistry. During WW I Fischer was responsible for organizing the production of chemicals in Germany. He committed suicide in 1919, after two of his sons had been killed in the war.

29 Dec 1919 Sir William Osler	science	death Sir William Osler Died 29 Dec 1919 at age 70 (born 12 Jul 1849). (Baronet) Canadian physician who revolutionized the medical curriculum in North America, adapting the best of the systems he had observed in England and Germany. He believed that students learn best by doing, teaching medical students at the bedside. He introduced postgraduate training system, instituting a general internship of one year to be followed by a residency of several years. His textbook, The Principles and Practice of Medicine (1892) included the advances of the previous half-century in clinical medical science, and remained the standard text for 40 years. Early in his life, in 1873, he made the most careful description to date of what later were called the "blood-platelets," which was presented to the Royal Society.
