JANUARY 27 – BIRTHS – Scientists born on January 27th
  Samuel C.C. Ting
baby icon  Born 27 Jan 1936.
Samuel Chao Chung Ting is an American physicist who shared (with Burton Richter) the 1976 Nobel Prize for Physics in 1976 for his discovery of a new subatomic particle, the J/psi particle.
  Sir John C. Eccles
baby icon  Born 27 Jan 1903; died 2 May 1997 at age 94.  quotes button quotes
John Carew Eccles was an Australian physiologist who shared, (with Alan Hodgkin and Andrew Huxley) the 1963 Nobel Prize for Physiology or Medicine for his discovery of the chemical means by which impulses are communicated or repressed by nerve cells. He also showed how signals pass between nerves and muscles. A nerve cell that is switched on by receiving a signal passes a chemical on to the next cell in line. This chemical expands minute openings in cell membranes, allowing ions to flood inside, reversing the electrical charge of the cell. This activity is repeated along the chain of cells, permitting transmission of the original impulse through the body. Eccles observed living cells in action by planting exceptionally tiny electrodes in them.
  Hyman G. Rickover
baby icon  Born 27 Jan 1900; died 8 Jul 1986 at age 86.  quotes button quotes
Hyman George Rickover was a Polish-American naval officer who immigrated to the US (1906) and graduated from the Naval Academy in 1922. He eventually became an Admiral. He is known as the “Father of the Nuclear Navy” for his leadership to build the atomic-powered submarine, USS Nautilus (1954). He served on active duty with the United States Navy for more than 63 years, receiving exemptions from the mandatory retirement age due to his critical service in the building of the United States Navy's nuclear surface and submarine force.

  Victor Moritz Goldschmidt
baby icon  Born 27 Jan 1888; died 20 Mar 1947 at age 59.  quotes button quotes
Swiss-Norwegian geochemist, mineralogist and petrologist who established a theoretical background for geochemistry (which in the previous century had been limited to the collection of data on the accessible earth's crust, waters and atmosphere.) Goldschmidt investigated the major and minor elements in minerals, and sought to explain their distribution as a result of cosmic origins. He invented crystal chemistry, whereby he attempted to complete a record of mineral crystal forms, and to link the variations of those forms to the physical and chemical conditions under which they were formed. In this pursuit, he both improved existing instruments and invented new ones. He is regarded as the founder of modern geochemistry.«

  Carl Blegen
baby icon  Born 27 Jan 1887; died 24 Aug 1971 at age 84.
Carl William Blegen was an American archaeologist who unearthed evidence that supported and dated the sack of Troy recorded in Homer's Iliad. Storage jars, skeletons and ash piles (which he interpreted as evidence of the city's fiery destruction) reinforced his conviction. He also discovered, in 1939, clay tablets dating from about 1250 BC. At the fabled palace of King Nestor, a major figure in the Trojan War, nearly 1,100 clay tablet records of palace transactions were found there over 15 years. These were inscribed with the earliest known examples of European writing, enabling cryptographers to find the key by which the ancient tablets could be decoded, proving the existence of a Greek civilization where none was formerly thought to exist.«

  Ralph Modjeski
baby icon  Born 27 Jan 1861; died 26 Jun 1940 at age 79.
Polish-American bridge designer and bridge builder who was outstanding for the number, variety, and innovative character of his projects. His first major commission was the design and construction of a seven-span bridge with railway and highway over the Mississippi River, at Rock Island, Illinois. Later, he developed a set of standard bridges designs for the Northern Pacific Railroad. He remains outstanding for the large number, variety and innovation of America's finest major bridges for which he was chief or consulting engineer. The longest cantilevered bridge in the world, the Quebec City Bridge, was completed when he took over its re-design following a 1907 failure that killed 75 workers. He was chief engineer of the San Francisco-Oakland Bay Bridge.«

  James Ward
baby icon  Born 27 Jan 1843; died 4 Mar 1925 at age 82.
English psychologist who had widespread influence on the practice and teaching of psychology in Great Britain, resulting particularly from his influential article (1886) in the ninth edition of the Encyclopaedia Britannica. Therein, he defined psychology's principal task as "to analyze and trace the development of individual experience as it is for the experiencing individual." For Ward, the mind is an active participant in experience. What is presented is not an aggregate of things which produce corresponding mental atoms, but a varying continuum to which the mind attends and selects. In 1904, The British Journal of Psychology began publication, edited by James Ward and W.H.R. Rivers.«
  Lewis Carroll
baby icon  Born 27 Jan 1832; died 14 Jan 1898 at age 65.  quotes button quotes
Charles Lutwidge Dodgson, pen-name Lewis Carroll, was an English logician, mathematician, photographer, and novelist, remembered for Alice's Adventures in Wonderland (1865) and its sequel. After graduating from Christ Church College, Oxford in 1854, Dodgson remained there, lecturing on mathematics and writing treatises until 1881. As a mathematician, Dodgson was conservative. He was the author of a fair number of mathematics books, for instance A Syllabus of Plane Algebraical Geometry (1860). His mathematics books have not proved of enduring importance except Euclid and his Modern Rivals (1879) which is of historical interest. As a logician, he was more interested in logic as a game than as an instrument for testing reason.
  Isaac Roberts
baby icon  Born 27 Jan 1829; died 17 Jul 1904 at age 75.
Welsh astronomer who was a pioneer in photography of nebulae. In 1885 he had built an observatory with a 20 inch reflector. Using this instrument Roberts was to make considerable progress in the newly developing science of Astro-photography. He photographed numerous celestial objects including Orion Nebula on 15 Jan 1986 (90 minute exposure) and Pleiades. Undoubtedly his finest work was a photograph showing the spiral structure of the Great Nebula in Andromeda, M31 on 29 Dec 1888. In addition to his contribution to astro-photography, Roberts also devised a machine to be used to engrave stellar positions on copper plates, known as the Stellar Pantograver. He was also a geologist of some considerable note.
  William H. Duncan
baby icon  Born 27 Jan 1805; died 23 May 1863 at age 58.
William Henry Duncan was an English physician who was appointed as a Chief Medical Officer, the first such salaried official in Britain, on 1 Jan 1847 in Liverpool, England. He was born of Scottish parents, in Liverpool, received his M.D. in Edinburgh (1829), then returned to Liverpool where he began general practice. He realized the city had poor housing and sanitation conditions for the working people, which threatened the public health with diseases that could be prevented by reform. His 1843 pamphlet, The Physical Causes of the High Mortality Rate in Liverpool, identifed the issues that raised the city's mortality rate far above other towns. Duncan helped create the city's first Sanitary Act (1846) and pioneered in the Victorian public health movement. He used the power of the media to spread public health messages, by holding weekly press conferences to keep a focus on public health and to advocate improvements.«

  Phineas Davis
baby icon  Born 27 Jan 1792; died 27 Sep 1835 at age 43.
clockmaker and inventor who turned from his self-taught skills making jewellery and timepieces to invent the first successful coal burning locomotive constructed in the U.S. Earlier, railroads used imported locomotives. On 4 Jan 1831, the Baltimore and Ohio Railroad Company advertised a prize of $4,000 for the best engine in trials conducted in Jun 1831. Davis created his York locomotive and won the trial. He then worked developing the engine for that railroad, but died only a few years later, in a train derailment accident.«
  Charles-Marie de La Condamine
baby icon  Born 27 Jan 1701; died 4 Feb 1774 at age 73.
French naturalist and mathematician who became particularly interested in geodesy (earth measurement). He was put in charge by the King of France of an expedition to Equador to measure a meridional arc at the equator (1735-43). It was wished to determine whether the Earth was either flattened or elongated at its poles. He then accomplished the first scientific exploration of the Amazon River (1743) on a raft, studying the region, and brought the drug curare to Europe. He also worked on establishment of a universal unit of length, and is credited with developing the idea of vaccination against smallpox, later perfected by Edward Jenner. However, he was almost constantly ill and died in 1773, deaf and completely paralyzed. Date of birth: DSB gives 27 Jan 1701; Enc. Brit. gives 28 Jan 1701.
  Thomas Willis
baby icon  Born 27 Jan 1621; died 11 Nov 1675 at age 54.
English physician who made important contributions to anatomy, particularly of the brain and nervous system. In De febribus (1659) he significantly advanced epidemiology with an examination of epidemics of smallpox, influenza, plague, war-typhus, measles, and the first medical description of the typhoid fever. As part of his investigation of the brain's circulation, he injected wax into the blood vessels, which enabled him to see a ring of vessels still known as the "circle of Willis." He identified a type of diabetes (diabetes mellitus). A club of scientists including Robert Boyle, Christopher Wren and John Wilkins met in his rooms (1648-9) in Oxford. A number of them became founding members of the Royal Society of London.«


Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath. (1882) -- Nathaniel Egleston, who was writing then about deforestation, but speaks equally well about the danger of climate change today.
Carl Sagan Thumbnail Carl Sagan: In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) ...(more by Sagan)

Albert Einstein: I used to wonder how it comes about that the electron is negative. Negative-positive—these are perfectly symmetric in physics. There is no reason whatever to prefer one to the other. Then why is the electron negative? I thought about this for a long time and at last all I could think was “It won the fight!” ...(more by Einstein)

Richard Feynman: It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly. ...(more by Feynman)

JANUARY 27 – DEATHS – Scientists died on January 27th
  Sir Thomas Octave Murdoch Sopwith
gravestone icon  Died 27 Jan 1989 at age 101 (born 18 Jan 1888).
English aircraft designer and aircraft manufacturer whose pioneering firm was famous for British WWI military aircraft. Sopwith's interest in motor racing led in 1910 to flying a monoplane, with which he won the Baron de Forest prize for flying across the English Channel on 18 Dec 1910. In June 1912, Sopwith with Fred Sigrist and others set up The Sopwith Aviation Company and began manufacturing the Sopwith Tabloid biplane. Piloted by Harry Hawker this plane won the British altitude record of 13,000 ft (4000 m) on 16 June 1913. During WWI, the firm manufactured some of the best Allied fighters, including the legendary Sopwith Camel (named after the fuselage shape with a humplike cowl over the guns, in front of the pilot), Sopwith Pup, and Sopwith Snipe. He lived to the age of 101.«

  Meyer Fortes
gravestone icon  Died 27 Jan 1983 at age 76 (born 25 Apr 1906).
English social anthropologist who is known for his investigations of West African societies. He originally training in psychology, but in 1932 turned to anthropology—which is reflected in his later works on ancestor worship. He was primarily interested in family and kinship, and made field studies (1934–37) with the Tallensi and Ashanti in Ghana. His monographs on these studies laid the foundations for the theory of descent, a cornerstone of the “structural-functionalism” dominating the social anthropology of the 1950s and 60s. His major contributions in lineage theory, studies of religion and ancestor worship set the standard for all subsequent studies of African social organization. He was professor of social anthropology at Cambridge University (1950-73).«

German-American mathematician who, upon joining the faculty of New York University in 1934, began to build the nucleus of a small research group based on the Göttingen model he had experienced as a student of David Hilbert in Germany. Courant's published papers were in variational problems, finite difference methods, minimal surfaces, and partial differential equations. He encouraged the publication of mathematical texts and high quality monographs, such as Methods of Mathematical Physics by Courant and Hilbert. His leadership was commemorated in 1964 when the institute he founded was named the Courant Institute of Mathematical Sciences at New York University.«

gravestone icon  Died 27 Jan 1970 at age 75 (born 29 Apr 1894).
Austrian nuclear physicist who began as a strong student in mathematics and physics at school, and studied physics at university, where she wrote her thesis on the absorption of gamma rays (1919). At first, she took a job (1921) with a manufacturer of x-ray tubes in Berlin. By 1923, she progressed to researching radioactivity with the Institut für Radiumforschung back in Vienna. There she developed the photographic emulsion technique for the study of nuclear disintegration caused by cosmic rays, and contributed to development of photomultiplier tubes. Blau was first to use nuclear emulsions to detect neutrons by observing recoil protons. Albert Einstein recognized her as a very capable experimental physicist, and after 1938 when she fled the rise of the Nazis, Einstein helped her career continue in Mexico City and then the U.S.«

First U.S. astronaut to walk in space. With James A. McDivitt he manned the four-day orbital flight of Gemini 4, launched on 3 Jun 1965. During the third orbit White emerged from the spacecraft, floated in space for about 20 minutes, and became the first person to propel himself in space with a maneuvering unit. Two years later, White was one of the three-man crew of Apollo 1 who in 1967 were the first casualties of the U.S. space program, killed during a flight simulation (the others were Virgil I. Grissom and Roger B. Chaffee).

American pediatrician who promoted the iodization of table salt sold in the U.S. to provide a dietary supplement of iodine, thus reducing the incidence of goitre (major swelling of the thyroid gland in the neck.) The value of sodium iodide for this purpose had been determined by David Marine. Cowie, a professor of pediatrics at the University of Michigan gathered support from the Michigan State Medical Society and pursuaded several table salt producers to add 0.01% sodium iodide to their product. Diamond Crystal Salt, and four other companies agreed. On 1 May 1924, the first iodized salt was on Michigan grocers' shelves. Initially reluctant, Morton Salt Company followed suit later in the year for the national market.«  read more button more
  Thomas Crapper

who owned a flourishing plumbing supply business and held several patents. Though he did not invent the familiar toilet flushing syphon mechanism (it was patented in Britain by Albert Giblin, No. 4990 of 1898), he did widely market it, and thus his name has been associated with it. Before this invention, the lavatory had existed in various forms, dating back to Sir John Harrington in 1589. When Victorian era toilets with poor valve designs were wasting too much water, by act of Parliament, a water-saving device was required. For this reason, the lever-activated syphon “pull and let go” mechanism was marketed as “Crapper's Silent Valveless Water Waste Preventer.”«

Sir Thomas Makdougall Brisbane was a British soldier and astronomical observer, Baronet British soldier and astronomical observer for whom the city of Brisbane, Australia, is named. He was Governor of NSW (1821-25). Mainly remembered as a patron of science, he built an astronomical observatory at Parramatta, Australia, made the first extensive observations of the southern stars since Lacaille in (1751-52) and built a combined observatory and magnetic station at Makerstoun, Roxburghshire, Scotland. He also conducted (largely unsuccessful) experiments in growing Virginian tobacco, Georgian cotton, Brazilian coffee and New Zealand flax.
  Jαnos Bolyai
gravestone icon  Died 27 Jan 1860 at age 57 (born 15 Dec 1802).
Hungarian mathematician and one of the founders of non-Euclidean geometry - geometry that does not include Euclid's axiom that only one line can be drawn parallel to a given line through a point not on the given line. His father, Farkas Bolyai, had devoted his life to trying to prove Euclid's famous parallel postulate. Despite his father's warnings that it would ruin his health and peace of mind, János followed in working on this axiom until, in about 1820, he came to the conclusion that it could not be proved. He went on to develop a consistent geometry (published 1882) in which the parallel postulate is not used, thus establishing the independence of this axiom from the others. He also did valuable work in the theory of complex numbers.
  John James Audubon
gravestone icon  Died 27 Jan 1851 at age 65 (born 26 Apr 1785).  quotes button quotes
John James Laforest Audubon was a French-American ornithologist, artist and naturalist known for his drawings and paintings of North American birds. He was born in Haiti, the illegitimate son of a successful merchant, planter, and slave dealer. At age 4, he was taken to France and educated among the well-to-do. By 15 he was drawing French birds. In 1803, Audubon was in Pennsylvania managing his father's estate where he began his ventures into ornithology. In 1820, he made his goal the publication of an anthology of life drawings. He traveled the Ohio and Mississippi Rivers and the Great Lakes, exploring for birds. Unable to find a publisher in America he travelled to London in 1826-27 where his engravings were made. In 1831, Audubon returned to the U.S. and spent more years travelling and painting. Image right: Trumpeter swan by Audubon (1837).

JANUARY 27 – EVENTS – Science events on January 27th
  Artificial sweetener patent issued
calendar icon   In 1970, James M. Schlatter received a patent for “Peptide Sweetening Agents” (U.S. No. 3,492,131), an invention which eventually led led to the marketing of aspartame under the name NutraSweet. The patent was filed 18 Apr 1966, assigned to his employer, G.D. Searle & Co. In Dec 1965, a  few months before filing,  he had accidentally discovered the first example of such compounds. To pick up a paper, he had licked his finger. He tasted an unexpectedly sweet trace of a substance that had, he realized, earlier splashed onto the outside of a flask he had handled. It contained L-aspartyl-L-phenylalnine methyl ester. After development and much scrutiny of the testing of aspartame, the U.S. Food and Drug Administration approved it (22 Oct 1981) with many permitted uses as a food sweetener.«
  Corfam
calendar icon   In 1964, E.I. duPont de Nemours Co. introduced Corfam. This hydrocarbon-based, synthetic substitute for leather was flexible, with tiny pores, for uses such as shoes, handbags, belts and suitcases. Shoes put on sale with Corfam uppers were supposed to give consumers the look, feel and durability of leather. DuPont predicted that by 1984, 25% of America's shoes would be made of Corfam. But synthetic leather was snubbed by customers in droves. It was one of the best-prepared products in terms of market and technology development and yet it failed. Time on the market: seven years. Production ceased in 1971. Corfam was described by Leonard Sloane in the New York Times as, "Du Pont's $100-Million Edsel," (11 Apr 1971).
  Terramycin announced
calendar icon   In 1950, Science magazine announced the new antibiotic terramycin. Made by Charles Pfizer & Co., it was isolated from Indiana soil, and found effective against pneumonia, dysentery, and other infections. It was the first pharmaceutical discovered and developed exclusively by Pfizer scientists. This was the result of the company's intensive quest to find new organisms to fight disease. Acting on theories that bacteria-fighting organisms would be found in soil, Pfizer solicited soil samples worldwide, received 135,000 soil samples and conducted more than 20 million tests. Said one of the researchers, “We got soil samples from the bottom of mine shafts... from the bottom of the ocean... from the desert... mountains and in between.” Terramycin® was approved by the U.S. Food and Drug Administration on 15 Mar 1950.
  Tape recorder
calendar icon   In 1948, Wire Recording Corporation of America announced the first magnetic wire recorder. It is lightweight and portable. The 'Wireway' machine with a built-in oscillator sold for $149.50. [Image: Wireway portable combination magnetic wire recorder and phonograph - ca. 1950]
  Baird demonstrates television
calendar icon   In 1926, John Logie Baird, a Scottish inventor, gave the first public demonstration of a true television system in London, launching a revolution in communication and entertainment. Baird's invention, a pictorial transmission machine he called a “televisor,” used mechanical rotating disks to scan moving images into electronic impulses. This information was then transmitted by cable to a screen where it showed up as a low-resolution pattern of light and dark. Baird's first television program showed the heads of two ventriloquist dummies, which he operated in front of the camera apparatus out of view of the audience.

1921
(source)
calendar icon   In 1921, Albert Einstein suggested the possibility of measuring the universe, which startled the audience, with his address Geometry and Expansion given at the Prussian Academy of Sciences in Berlin. Applying certain results of the relativity theory, he came to the conclusion that if the real velocities of the stars (as could be actually measured) were less than the calculated velocities, then it would prove that real gravitations' great distances were smaller than the gravitational distances demanded by the law of Newton. From such divergence, the finiteness of the universe could be proved indirectly, and it would even permit the estimation of its size.«

  National Geographic Society founded
calendar icon   In 1888, the National Geographic Society was established with Gardiner Greene Hubbard as its first president. Two weeks earlier, on 13 Jan 1888, 33 founders in Washington, D.C., U.S.A., had met at the Cosmo Club in Lafayette Square, across from the White House. Their mission was to establish “a society for the increase and diffusion of geographical knowledge.” By Oct 1888, the first National Geographic Magazine was published as a society membership benefit, which continues its monthly issues to the present with photographs and popular articles now expanded from topics of geography and exploration to science, history and world cultures. The society has awarded over 9,000 grants for scientific research, and sponsors a museum and travelling exhibits.«
  Incandescent lamp
Thumbnail - Incandescent lamp
calendar icon   In 1880, Thomas Edison received a patent (#223,898) for his electric incandescent lamp he invented on 21 Nov 1879. Edison's invention of the light bulb had a major impact on the electronics and computer industries. During the two years of research it took to develop the bulb, one of Edison's assistants noticed a flow of energy from one electrode to another in a pattern later known as the Edison effect. Later, the Edison effect was discovered to be an electron flow, which laid the basis for the electron tube and thence the entire electronics industry.
