OCTOBER 23 – BIRTHS – Scientists born on October 23rd
  Ted Fujita
baby icon  Born 23 Oct 1920; died 19 Nov 1998 at age 78.
Tetsuya Theodore Fujita was a Japanese-American meteorologist who increased the knowledge of severe storms. In 1953, he began research in the U.S. Shortly afterwards, he immigrated and established the Severe Local Storms Project. He was known as "Mr. Tornado" as a result of the Fujita scale (F-scale, Feb 1971), which he and his wife, Sumiko, developed for measuring tornadoes on the basis of their damage. Following the crash of Eastern flight 66 on 24 Jun 1975, he reviewed weather-related aircraft disasters and verified the downburst and the microburst (small downburst) phenomena, enabling airplane pilots to be trained on how to react to them. Late in his career, he turned to the study of storm tracks and El Nino.«

  Manolis Andronicos
baby icon  Born 23 Oct 1919; died 30 Mar 1992 at age 72.
Greek archaeologist who discovered ancient royal tombs in northern Greece, possibly belonging to the Macedonian King Philip II, the father of Alexander III the Great. In autumn 1977, an Andronicos discovered the unplundered royal tomb containing works of art of astounding richness and exquisite craftsmanship at Vergina in Macedonia. His suggestion that the tomb's occupant was probably Philip, son of Amyntas, king of the Macedonians, created understandable sensation, and aroused world-wide interest.

  Ilya Mikhaylovich Frank
baby icon  Born 23 Oct 1908; died 22 Jun 1990 at age 81.
Russian physicist who, with Igor Y. Tamm, theoretically explained the mechanism of Cherenkov radiation. In 1934, Cherenkov discovered that a peculiar blue light is emitted by charged particles traveling at very high speeds through water. Frank and Tamm provided the theoretical explanation of this effect, which occurs when the particles travel through an optically transparent medium at speeds greater than the speed of light in that medium. This discovery resulted in the development of new methods for detecting and measuring the velocity of high-speed particles and became of great importance for research in nuclear physics. For this, Frank received the Nobel Prize for Physics in 1958 (jointly with Pavel A. Cherenkov and Igor Y. Tamm).
  Felix Bloch
baby icon  Born 23 Oct 1905; died 10 Sep 1983 at age 77.
Swiss-born American physicist who shared (with independent discoverer, E.M. Purcell) the Nobel Prize for Physics in 1952 for developing the nuclear magnetic resonance (NMR) method of measuring the magnetic field of atomic nuclei. He obtained his PhD under Werner Heisenberg in 1928, then taught briefly in Germany, but as a Jew, when Hitler came to power, he left Europe for the USA. Bloch's concept of magnetic neutron polarization (1934) enabled him, in conjunction with L. Alvarez, to measure the neutron's magnetic moment. During WW II he worked on the atomic bomb. Thereafter, Bloch and co-workers developed NMR, now widely used technique in chemistry, biochemistry, and medicine. In 1954 he became the first director of CERN.
  Ernest Julius Φpik
baby icon  Born 23 Oct 1893; died 10 Sep 1985 at age 91.
Estonian astronomer who is best known for his studies of meteors and meteorites, and whose life work was devoted to understanding the structure and evolution of the cosmos. When Soviet occupation of Estonia was imminent, he moved to Hamburg, then to Armagh Observatory, Northern Ireland (1948-81). Among his many pioneering discoveries were: (1) the first computation of the density of a degenerate body, namely the white dwarf 40 Eri B, in 1915; (2) the first accurate determination of the distance of an extragalactic object (Andromeda Nebula) in 1922; (3) the prediction of the existence of a cloud of cometary bodies encircling the Solar System (1932), later known as the “Oort Cloud”; (4) the first composite theoretical models of dwarf stars like the Sun which showed how they evolve into giants (1938); (5) a new theory of the origin of the Ice Ages (1952).
  Edwin G. Boring
baby icon  Born 23 Oct 1886; died 1 Jul 1968 at age 81.  quotes button quotes
Edwin Garrigues Boring was an American psychologist who was first recognized for his experimental work but later known as a historian of psychology. When the U.S. entered WW I, Robert M. Yerkes recruited Boring to help test the intelligence of draftees. In 1922, he was invited to Harvard, where he began a long and productive career as director of the psychological laboratory (1924-49). To free psychology from its status as part of the Dept. of Philosophy, Boring succeeded in establishing a separate Dept of Psychology (1934). Upon retirement, he was appointed Edgar Pierce Professor Emeritus and continued to teach classes until he was nearly 71. Throughout his life, he wrote textbooks and edited professional journals.
  Gilbert Newton Lewis
baby icon  Born 23 Oct 1875; died 23 Mar 1946 at age 70.  quotes button quotes
American chemist who collaborated with Irving Langmuir in developing an atomic theory. He developed a theory of valency, which introduced the covalent bond (c. 1916), whereby a chemical combination is made between two atoms by the sharing of a pair of electrons, one contributed from each atom. This was part of his more general octet theory, published in Valence and the Structure of Atoms and Molecules (1923). Lewis visualized the electrons in an atom as being arranged in concentric cubes. The sharing of these electrons he illustrated in the Lewis dot diagrams familiar to chemistry students. He generalized the concept of acids and bases now known as Lewis acids and Lewis bases.«

  William Coolidge
baby icon  Born 23 Oct 1873; died 3 Feb 1975 at age 101.  quotes button quotes
William David Coolidge was an American physicist, engineer and physical chemist whose improvement of tungsten filaments (U.S. patent No.1,082,933, issued 30 Dec 1913) was essential in the development of the modern incandescent lamp bulb and the X-ray tube. Coolidge's X-ray tube (1916, U.S. patent No. 1,203,495) completely revolutionized the generation of X-rays and remains to this day the model upon which all X-ray tubes for medical applications are patterned. He worked on many other devices such as high-quality magnetic steel, improved ventilating fans, and the electric blanket. During World War II he contributed research to projects involving radar and radar countermeasures. He was awarded 83 patents during his lifetime.

  Frederick William Lanchester
baby icon  Born 23 Oct 1868; died 8 Mar 1946 at age 77.
English automobile and aeronautics pioneer who built the first British petrol automobile (1896) and founded the Lanchester Engine Co in 1899. In 1901, Lanchester patented disc brakes. His production cars were scientifically designed and owed little to their competitors. His 1903 car had a balanced "vibrationless" two-cylinder horizontal engine with two counter-rotating crankshafts, electric ignition, 3 speed epicyclic gearbox with pre-selector control, tiller steering and a worm drive back axle. In 1907-8, he published an important two-volume work on aerodynamics. Lanchester is recognized as the first to grasp the role of the trailing vortices behind lifting wings and as the initiator of the circulation theory of lift. He also founded mathematical modelling for military gaming.
  Ludwig Leichhardt
baby icon  Born 23 Oct 1813; died 4 Apr 1848 at age 34.
(Friedrich Wilhelm) Ludwig Leichhardt was a German explorer and naturalist who went to Australia in 1842 to study the rocks and wildlife in Queensland and the Northern Territory. In 1846 he left on an expedition with nine men to find a route from Moreton Bay (Brisbane) to Perth, rather poorly equipped. The party disappeared, leaving a mystery as to its fate which nine major expeditions in the next 90 years failed to solve. On previous travels he discovered many important rivers and reported on land suitable for grazing, but with difficulties of poor leadership and planning. His first trip (1844) ran out of supplies, and was forced to live on wildlife. In an encounter with hostile aborginals, one man was killed and two injured.«
  Samuel Morey
baby icon  Born 23 Oct 1762; died 17 Apr 1843 at age 80.
American inventor that one author called “the Edison of his day.” His inventions include raising water by wind (patented 11 Apr 1796), a rotary steam engine (14 Jul 1815), a fuel-saving fireplace (18 Jan 1813), a tide and current water wheel (13 Mar 1817), and shooting by steam (19 Jan 1819). Morey's earliest patent (26 Jan 1793), one of the first (No. X51) to be issued in the U.S., was for a rotating, steam-powered cooking spit for roasting meat, and was signed by George Washington. His next patent (25 Mar 1795) was for a steam engine to power boats, years before Robert Fulton. He developed a method for production of water gas fuel (a mixture of carbon monoxide and hydrogen from steam passed over heated carbon substances), patented as his “American Water Burner” (11 Dec 1817). On 1 Apr 1826, he was issued the first U.S. patent for an internal-combustion engine titled “Gas or Vapour Engine.”« [Image, drawn for a magazine (1909) is likely (?) from the artist's imagination.

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)

OCTOBER 23 – DEATHS – Scientists died on October 23rd
  Herbert A. Hauptman
gravestone icon  Died 23 Oct 2011 at age 94 (born 14 Feb 1917).
Herbert Aaron Hauptman was an American mathematician and crystallographer who shared the 1985 Nobel Prize for Chemistry with Jerome Karle, with whom he collaborated, “for their outstanding achievements in the development of direct methods for the determination of crystal structures.” They developed mathematical methods for interpreting the patterns formed on photographic film by X rays diffracted through a crystalline chemical compound to determine its molecular structure. The knowledge of structure has two great benefits. One, in understanding the function of molecules in biological contexts, expecially those of “signal - receptor processes.” These include such processes as enzyme activity; antigen - antibody; and scent substance - scent receptor. Another is in studying the mechanism and chemical dynamics of reactions.«

Turkish-born American whose over 200 inventions included the TelePrompter, a self-posing portrait camera, automatic postage metering equipment, and an indoor golf practice range. In WW II, his Range Estimation Trainer provided a simulator for pilots to learn to identify aircraft types, their distance and speed. It used synchronized moving mirrors, controlled lighting and a miniature airplane to present various speeds, lighting, and angles. From 1939, he held 20 patents for an early form of an automated teller machine, and in 1960 his Bankograph (US patent No. 3,079,603) was given a trial by New York's First National City Bank (now CitiBank). It was able to take deposits, photograph the money and issue a receipt showing those images.«  read more button more
  Edward A. Doisy
gravestone icon  Died 23 Oct 1986 at age 92 (born 13 Nov 1893).
Edward Adelbert Doisy was an American biochemist who shared (with Henrik Dam) the 1943 Nobel Prize for Physiology or Medicine for his isolation and synthesis of vitamin K, a substance that encourages blood clotting (1939), used in medicine and surgery. With the embryologist Edgar Allen (1922-34), he developed assay techniques that facilitated research on sex hormones. Doisy and his associates isolated the sex hormones estrone (theelin, 1929; the first estrogen to be crystallized), estriol (theelol, 1930), and estradiol (dihydrotheelin, 1935). In 1936-39 he isolated two forms of the vitamin, (K1 from lucerne seed and K2 from fish meal, in a pure crystalline form), determined their chemical structures, and synthesized the vitamin.«

  Stuart Criddle
gravestone icon  Died 23 Oct 1971 at age 93 (born 4 Dec 1877).
English-born Canadian farmer, mammalogist, and plant breeder who kept meticulous field notes of mammal (and bird) life. He carried out many breeding experiments with sunflowers, corn, and lilies and had a new variety of lily named after him. He was a charter member of the American Society of Mammalogists. Although he had no formal schooling, he was awarded an honorary D.Sc. at the first convocation of Brandon University in 1968. His older brother Norman Criddle was known as the "dean of entomology" in western Canada, and is recognized for his development of the "Criddle mixture" for grasshopper control and for his early application of biological observations to insect control. Stuart immigrated into Canada as a boy with his family in 1882.
  Ernest Thompson Seton
gravestone icon  Died 23 Oct 1946 at age 86 (born 14 Aug 1860).  quotes button quotes
English-American naturalist who applied these skills in over forty books on wild life, woodcraft, Indian lore and animal-fiction stories. As a capable naturalist, in his field observations he made detailed studies of morphology, physiology, distribution, and behaviour. His fame as author began with Wild Animals I Have Known (1898) - still in print a century later. Over a period of twenty years he delivered over three thousand lectures. Believing in promoting the values of ethology and ecology, he was chairman of the committee that established the Boy Scouts in the U.S. (1910). Seton envisioned the North American Indian as a model for the movement, but Baden-Powell's military structure was adopted as in Britain.«  read more button more

  Charles Barkla
gravestone icon  Died 23 Oct 1944 at age 67 (born 7 Jun 1877).
Charles Glover Barkla was an English physicist who was awarded the Nobel Prize for Physics in 1917 for his work on X-ray scattering. This technique is applied to the investigation of atomic structures, by studying how X-rays passing through a material and are deflected by the atomic electrons. In 1903, he showed that the scattering of x-rays by gases depends on the molecular weight of the gas. His experiments on the polarization of x-rays (1904) and the direction of scattering of a beam of x-rays (1907) showed X-rays to be electromagnetic radiation like light (whereas, at the time, William Henry Bragg who held that X-rays were particles.) Barkla further discovered that each element has its own characteristic x-ray spectrum.«
  John Boyd Dunlop
gravestone icon  Died 23 Oct 1921 at age 81 (born 5 Feb 1840).
Scottish inventor who was a pioneer of the pneumatic tyre. In 1887, when his 9-yr-old son complained of the rough ride he experienced on his tricycle over the cobbled streets of Belfast. Dunlop devised and fitted rubber air tubes held on to a wooden ring by tacking a linen covering fixed around the wheels. Due to the major improvement in riding comfort, Dunlop continued development, until he patented the idea, issued on 7 Dec 1889 (No. 10607) as "An improvement in Tyres of Wheels for Bicycles, Tricycles or other Road Cars".

(USPTO)
gravestone icon  Died 23 Oct 1868 at age 67 (born 4 Sep 1801).
American inventor and machinist of Providence, RI, who patented the first practical screw machine in the U.S. for making pointed screws (14 Dec 1852, No. 9,477). Early screws had blunt ends, and it was necessary to drill a starter hole. In Oct 1840, he was one of ten incorporators of The New England Screw Co. He invented a machine for the company to use cutting the threads of screws (patented 18 Aug 1842), another for shaving the heads of screws (patented 6 Apr 1843) and one for removing the burs left in cutting the slots in the heads (patented 19 Apr 1843). He invented and patented seven other machines or devices for improving the manufacture of screws, such as a Screw-Blank Feeding mechanism (3 Jun 1856, No.15,052).«

  Oldest fossils
calendar icon   In 1977, American paleontologist Elso S. Barghoorn of Harvard announced the discovery of Pre-Cambian spherical one-celled algae microfossils (named Eobacterium) 3.4 billion years old, earth's earliest life forms. Barghoorn, with J. William Schopf, studied the ancient chert (a flintlike or quartz-like rock) of the Fig Tree formation in Transvaal, South Africa. Rubidium and strontium ratios in the chert are used to establish the age of the rock, and the fossils contained in it. The fossils are a kind of Prokaryotes, organisms with simple cell wall containing organic chemicals, and examples of cell division are visibile in the remains. A huge number of varieties exist today. They all produce oxygen; and, in the Precambrian period, began to change the earth's primoidal reducing atmosphere to the oxygenated one we have today.
  Married Nobel laureates
calendar icon   In 1947, the first American husband and wife team to win a Nobel Prize, Carl and Gerty Cori (née Radnitz) of Washington University Medical School, were awarded the Physiology or Medicine Prize for “the discovery on how glycogen is converted to glucose in the body, and for the effects of hypophysis hormones on sugar metabolism.” The prize was shared with Pierre and Marie Curie were awarded the Nobel Prize in Physics “in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel.” (Marie was born in Poland.)«

calendar icon   In 1814, the first modern plastic surgery was performed at the Duke of York's Hospital, Chelsea, England. The surgeon, Joseph Carpue, had read letter by a British surgeon, Lucas, in Oct 1794 in the Gentleman's Magazine. Lucas described a successful procedure performed in India whereby a forehead flap was used to reconstruct a man's mutilated nose, which had been deliberately mutilated by enemies of the British East Indian forces. (Hindu texts, up to 2600 years ago, have described various reconstruction techniques.) Having first practiced on several cadavers, Carpue operated on a British military officer who had lost his nose to the toxic effects of mercury treatments, and another whose nose was mutilated by a sword.«  read more button more
