| Sally Ride | |
(source) |
The first American woman to orbit the earth when she flew aboard Space Shuttle Challenger on 18 Jun 1983. Only two other women preceded her in space: Valentina Tereshkova (1963) and Svetlana Savitskaya (1982), both from the former Soviet Union. Ride applied to the astronaut program after reading an ad in a newspaper. Out of 8,000 applicants to the space program that year, 35 individuals were selected including six women. Accepted into the astronaut corps in 1978, she completed her training as a mission specialist in 1979, and flew on two missions with Challenger, the second in 1984. Dr. Ride, who has a Ph.D. degree in physics, was a member of the team chosen to investigate the 1986 explosion of Challenger. |
| Robert M. Yerkes | |

Robert Mearns Yerkes was an American psychologist and a principal developer of comparative (animal) psychology in the U.S. In his book The Dancing Mouse (1908), he helped established the use of mice and rats as standard subjects for experiments in psychology. He also studied primates, publishing his results in 1929 in the classic book The Great Apes. |
| Julius Stieglitz | |
(source) |
U.S. chemist who interpreted the behaviour and structure of organic compounds in the light of valence theory and applied the methods of physical chemistry to organic chemistry. His research in such fields as molecular rearrangements and stereochemistry helped lay the foundations of physicoorganic chemistry. During World War I, he advised the government on how to overcome shortages of chemicals which had come from Germany. He was very active in World War I developing war gases, dyes, and chemicals for the American military forces. He served as chairman of the committee on synthetic drugs of the National Research Council. |
| Washington Augustus Roebling | |
(source) |
U.S. civil engineer under whose direction the Brooklyn Bridge, New York City, was completed in 1883. The bridge was designed by Roebling with his father, John Augustus Roebling, from whom he had gained experience building wire-rope suspension bridges. Upon his father's death, he superintended the building of the Brooklyn Bridge (1869-83). He was disabled by decompression sickness after entering a caisson in 1872. He was brought out nearly insensible and his life was saved with difficulty. Because of resulting poor health, he directed operations from his home in Brooklyn overlooking the site. Though he continued to head the family's wire-rope manufacturing business for several years, medical problems forced retirement (1888). |
| Richard Christopher Carrington | |
(source) |
English astronomer who was the first to map the motions of sunspots and thus discover from them that the Sun rotates faster at the equator than near the poles (equatorial acceleration). He observed that the sunspots were not attached to any solid object, and also discovered the movement of sunspot zones toward the Sun's equator as the solar cycle progresses. On 1 Sep 1859, Carrington was the first to record the observation of a solar flare. (Image: detail of a drawing by R.C. Carrington, showing the location of the flare he observed while making a drawing of an active region. Reproduced from his 1860 paper in Monthly Notices of the Royal Astronomical Society) |
| Heinrich Geissler | |
(sourcce) |
German glassblower for whom the Geissler (mercury) vacuum pump and the Geissler tube are named. With the unprecedented (1/100 mm of mercury) low vacuum he produced in sealed glass tubes, he made available to early physicists a valuable tool to study the effect of electricity on the remaining traces of gases therein. These produced more detailed studies of the structure of matter. |
| Abraham de Moivre | |
(source) |
French mathematician who was a pioneer in the development of analytic trigonometry and in the theory of probability. He published The Doctrine of Chance in 1718. The definition of statistical independence appears in this book together with many problems with dice and other games. He also investigated mortality statistics and the foundation of the theory of annuities. He died in poverty, and correctly predicted the day of his own death. He found that he was sleeping 15 minutes longer each night and from this the arithmetic progression, calculated that he would die on the day that he slept for 24 hours. |

| Gerald S. Hawkins | |
(source) |
Gerald Stanley Hawkins was a British-born American radio-astronomer who used a computer to show that the stones and other archaeological features at Stonehenge formed a pattern of alignments with 12 major lunar and solar events, suggesting that it was used as a sort of neolithic observatory or astronomical calendar. In the 18th century, William Stukely had noticed that the horseshoe of trilithons and 19 bluestones opened up in the direction of the midsummer sunrise. In the 1960s, Hawkins, a British-born radio astronomer, identified 165 key points in the neolithic complex and found that many were strongly correlated with the rising and setting positions of the sun and moon over an 18.6-year cycle. In the 1990s, he studied the geometry of crop circles. |
| Waldo Semon | |
(source) |
American chemical engineer who invented plasticized PVC (vinyl). In 1926's, he discovered how to convert polyvinyl chloride from a hard, unworkable substance to a pliable one. It is now used in hundreds of products such as floor tile, garden hose, imitation leather, shower curtains, and coatings. It is produced in larger quantities than any other plastic except polyethylene. Semon also made pioneering contributions in polymer science, including new rubber antioxidants. His technical leadership led to discovery of three major new polymer families: thermoplastic polyurethane, synthetic "natural" rubber, and oil-resistant synthetic rubbers. Semon held 116 U.S. patents. |
| John Jacob Abel | |
(source) |
American pharmacologist and physiological chemist who made important contributions to a modern understanding of the ductless, or endocrine, glands. In 1893, he became the first full-time professor of pharmacology in the U.S. at John Hopkins University. Abel encouraged his students to conduct experiments and become active participants in his laboratory research. In 1897 he reported the isolation of a derivative of epinephrine (adrenaline). In 1926, he isolated and crystallized insulin. Abel also investigated the functions of the kidney and devised a vividiffusion apparatus for removing toxins from the blood of living animals, an apparatus that is widely regarded as a forerunner of the artificial kidney. |
| William Thomas Councilman | |
(source) |
American pathologist, remembered for his contribution in a monograph on amoebic dysentery (1891) which described detailed observations of it and its parasite. His post-M.D. (1878) work included many autopsies, sparking his interest in pathology. He studied in Europe (1880-83), where pathology was more advanced than in the U.S. In his first significant research, he confirmed Laveran's discovery of the sporozoan parasite that causes malaria, Plasmodium malariae (1893-94), and upon returning home, was the first in the U.S. to describe and picture it. Councilman also did research on diphtheria, cerebrospinal meningitis, nephritis, and smallpox. He was the principal founder of the American Association of Pathologists and Bacteriologists. |
| Ernest Solvay | |
(source) |
Belgian industrial chemist who invented the Solvay Process (1863), a commercially viable ammonia-soda process for producing soda ash (sodium carbonate), widely used in the manufacture of such products as glass and soap. Although a half-century before, A.J. Fresnel had shown (1811) that sodium bicarbonate could be precipitated from a salt solution containing ammonium bicarbonate, many engineering obstacles had to be overcome. Solvay's successful design used an 80 foot tall high-efficiency carbonating tower in which ammoniated brine trickled down from above and carbon dioxide rose from the bottom. Plates and bubble caps helped create a larger surface over which the two could react forming sodium bicarbonate. |
| Ascanio Sobrero | |
(source) |
Italian chemist who discovered the explosive compound nitroglycerin (1847) by adding glycerine slowly to mixture of nitric and sulphuric acids. When he discovered the explosive power of even a single drop in a test tube, he named the new compound pyroglycerin. Sobrero was horrified by the destructive potential of his discovery, and made no effort to develop that power himself, though it became known as nitroglycerin, or blasting oil. Two decades later, Nobel combined nitroglycerine with diatomaceous earth, making it safer to handle, but just as useful for blasting rock for construction and mining. Nobel made a fortune as the inventor and manufacturer of dynamite. |
| Isaac Babbitt | |
(source) |
American inventor of an alloy (babbitt's metal: tin 89%,antimony 7%, copper 4%.) widely used for friction reducing babbitt bearings. In 1924, he founded a company that has become Reed & Barton, the nation's oldest independent silversmiths. From 1834, he was superintendent of Alger's Foundry and Ordnance Works (South Boston Iron Works), where he cast the first brass cannon made in the U.S. He patented his successful invention of a journal box for train axles 17 Jul 1739, which suggested the bearings alloy. |
| Lord James Burnett Monboddo | |
(source) |
Scottish jurist and pioneer anthropologist who explored the origins of language and society and in some respects anticipated principles of Darwinian evolution. In his theory, he maintains that man was at first a mere animal, that he walked on all fours, and that he possessed a tail, of which we discover the rudiments. There has been a progression in mankind from one stage to higher, they erect themselves, they learn the use of their hands, and they learn to swim. They lived first on natural fruits, and then learned hunting and fishing. He is not so trustworthy as Darwin in his facts: he tells us that there is a whole nation of Esquimaux with only one leg; that in Ethiopia men have only one eye, and this in their foreheads and he believed in mermaids. |
| Bede | |
(source) |
Anglo-Saxon theologian, historian and scholar whose writings established the use of BC and AD with dates. He applied a knowledge of astronomy for the purpose of calculating the correct date for Easter. He found that due to an imperfection in Sosigenes' Julian calendar, that the vernal equinox had slipped to a point three days before the traditional date of 21 Mar. However, no action was taken to make the necessary adjustment in the number of leap years per millenium until nine centuries later. Bede held that the earth was a sphere. He preserved Pytheas' suggestion relating tides to the phases of the moon, and followed Seleucus' idea that a high tide is a local effect and does not occur everywhere at the same point in time. |
