  Daniel Chonghan Hong
baby icon  Born 3 Mar 1956; died 2 Jul 2002 at age 46.
Korean theoretical physicist specializing in statistical physics and nonlinear dynamic physics, who with colleague Hugo Caram, originated the void diffusing-void model of granular flow, which is recognized as an effective theoretical treatment for a broad range of dynamical phenomena in granular media. In general, his work ranged from percolation network, viscous fingering, granular flows to traffic equations. He studied and taught in America from 1981, and wrote articles for popular magazines on various topics. He died at the young age of 46 of cardiac arrest.«
  Arthur Kornberg
baby icon  Born 3 Mar 1918; died 26 Oct 2007 at age 89.
American biochemist and physician who shared the 1959 Nobel Prize for Physiology or Medicine (with Severo Ochoa) for the “discovery of the mechanisms in the biological synthesis of deoxyribonucleic acid” Kornberg showed not only how DNA molecules are duplicated both in nature within bacterial cells, but also isolated the first DNA polymerising enzyme (1958), and reproduced the process in the test tube. His research included studying the nucleic acids which control heredity in animals, plants, bacteria and viruses.«

Austro-German mathematician who worked in algebraic number theory, made a major contribution to field theory, and stated a law of reciprocity which included all previously known laws of reciprocity (1927). He also worked on the theory of braids (1925), and on rings with the minimum condition on right ideals, now called Artinian rings (1944). Artin has the distinction of solving (1927) one of the famous 23 problems previously posed by Hilbert in 1900. With his Jewish wife, he left Nazi Germany in 1937, and worked at universities in the U.S. until 1956, when he returned to his home country.«

  Sir Cyril Burt
baby icon  Born 3 Mar 1883; died 10 Oct 1971 at age 88.  quotes button quotes
British psychologist who was a leader in developing methods of statistical data analysis, particularly factor analysis, in psychological testing. He investigated the role of heredity in intelligence with twin studies and the role of nuture in juvenile deliquency. In 1913, he was appointed thea school psychologist for the schools administered by the London County Council (LCC) This was the first appointment of this kind in the U.K. In 1926, he proposed a national testing program of intelligence tests on children at about age 11. Subsequently, the national "Eleven-Plus" exam was used to identify whether children were high scorers suitable for education at a grammar schools, or not. After Burt's death his later work on twins was questioned as flawed or fraud

  Elmer McCollum
baby icon  Born 3 Mar 1879; died 15 Nov 1967 at age 88.
American biochemist who originated the letter system of naming vitamins. He discovered vitamins A, B and worked with others on vitamin D. He performed extensive research work in nutrition and growth. He was the first in the U.S. to establish a colony of white rats as laboratory animals to be the subject of his nutrition experiments. In the 1910's, he recognized that a healthy diet required certain fats, and he named the essential component "fat-soluble A," as distinct from another he named "water-soluble B." Although at first he thought each was a single compound, he later showed that they were in fact complexes. He researched how certain minerals were important as nutrients, including calcium, phosphorus, fluorine, manganese and zinc.«

  Henry Wetherbee Henshaw
baby icon  Born 3 Mar 1850; died 1 Aug 1930 at age 80.
American naturalist, ornithologist, and ethnologist. From 1872-79, he made annual field trips to various parts of the West as naturalist with the Wheeler Survey, exploring west of the one-hundredth meridian, and prepared reports to Washington. In addition to making a notable collection of birds, he took an interest in other branches of natural history. In 1885 his collection of birds and eggs was acquired by the British Museum. During a period while ornithological work was available, he worked for the Bureau of Ethnology.
  Alexander Graham Bell
baby icon  Born 3 Mar 1847; died 2 Aug 1922 at age 75.  quotes button quotes
Scottish-American inventor of the telephone. Bell's career was influenced by his grandfather (who published The Practical Elocutionist and Stammering and Other Impediments of Speech), his father (whose interest was the mechanics and methods of vocal communication) and his mother (who was deaf). As a teenager, Alexander was intrigued by the writings of German physicist Hermann Von Helmholtz, On The Sensations of Tone. At age 23 he moved to Canada. In 1871, Bell began giving instruction in Visible Speech at the Boston School for Deaf Mutes. This background set his course in developing the transmission of voice over wires. He cofounded Bell Telephone Co in 1877. With his father-in-law, he re-established the journal Science (1882).«

  Georg Cantor
baby icon  Born 3 Mar 1845; died 6 Jan 1918 at age 72.  quotes button quotes
Georg (Ferdinand Ludwig Philipp) Cantor was a Russian-German mathematician who created modern set theory and extended it to give the concept of transfinite numbers,with cardinal and ordinal number classes. Although Cantor's earliest work was concerned with Fourier series, his reputation rests upon his contribution to transfinite set theory. He began with the definition of infinite sets proposed by Dedekind in 1872: a set is infinite when it is similar to a proper part of itself. Sets with this property, such as the set of natural numbers are said to be 'denumerable' or 'countable'. His career was repeatedly interrupted after 1884 by mental illness. He died of heart failure in 1918 in a mental institution.
  Sir William Chandler Roberts-Austen
baby icon  Born 3 Mar 1843; died 22 Nov 1902 at age 59.
English metallurgist whose research on the physical properties of metals and their alloys had many practical and industrial applications. He established methods to determine the composition of an alloy, invented an automatic recording pyrometer to track the temperature changes of furnaces and their molten contents and. researched diffusion between a sheet of gold and a block of lead. He was a professor at the Royal School of Mines, and from 1882 a chemist and assayer at the Mint, becoming a world authority on the technical aspects of minting coins. He was knighted in 1899. Austenite (a non-magnetic solid solution of ferric carbide or carbon in iron, used in making corrosion-resistant steel) was named after him.«

  Sir John Murray
baby icon  Born 3 Mar 1841; died 16 Mar 1914 at age 73.
Scottish naturalist who, as one of its founders, coined the name oceanography. He studied ocean basins, deep-sea deposits, and coral-reef formation. As a marine scientist, he took part in the Challenger Expedition (1872-76), the first major oceanographic expedition of the world. He was first to observe the Mid-Atlantic Ridge and the existence of marine trenches. He attempted with Buchan to construct from temperature and salinity observations a qualitative theory of water movement in the world's oceans. With Alexander Agassiz, he put forward a modified hypothesis for coral reef development, arguing against Charles Darwin's hypothesis and suggesting that subsidence was not always a controlling mechanism. He died in 1914, killed by a motor car.
  George William Hill
baby icon  Born 3 Mar 1838; died 16 Apr 1914 at age 76.
U.S. mathematical astronomer considered by many of his peers to be the greatest master of celestial mechanics of his time. Hill joined the Nautical Almanac Office in 1861. He computed the orbit of the moon while making original contributions to the three body problem. He introduced infinite determinants, a concept which later found application in many fields of mathematics and physics. When Simon Newcomb took over the Nautical Almanac in 1877 and began a complete recomputation of all solar system motions, Hill was assigned the difficult problem of the orbits of Jupiter and Saturn. After completing the enormous labor in ten years, he returned to his farm, where he continued his research in celestial mechanics.
  George M. Pullman
baby icon  Born 3 Mar 1831; died 19 Oct 1897 at age 66.
George M(ortimer) Pullman was an American industrialist and inventor of the Pullman sleeping car for use on railroads.
  Pierre Prιvost
baby icon  Born 3 Mar 1751; died 8 Apr 1839 at age 88.
Swiss physicist and philosopher who first showed that all bodies radiate heat, no matter how hot or cold they are. In Sur l'equilibre du feu (1792) he made a significant step forward in understanding the nature of heat. With the Prévost theory of exchanges, he introduced the concept of dynamic equilibrium in which all bodies are both radiating and absorbing heat to and from the surroundings at the same rate. (As opposed to the two “imponderable fluids” of frigoric (cold) and caloric (heat) widely believed at the time.) Prévost recognized that cooling was the loss of heat, not the gain of cold. He believed all bodies contained some measure of heat at any temperature, and that heat would flow from a hotter body to a colder body. This interpretation in his caloric theory remained true when described seventy years later in Maxwell's kinetic theory (that heat is energy of particle motion). In his later years, Prévost studied the human aging process, using himself as the subject of his observations.
  Andreas Marggraf
baby icon  Born 3 Mar 1709; died 7 Aug 1782 at age 73.
Andreas Sigismund Marggraf was a German chemist who was a member of the Royal Academy of Science and Literature of Berlin. In 1747, Marggraf demonstrated that various kinds of beet-root contained sugar and that the sugar could be extracted and crystallized. This discovery, however, was regarded for many years as being merely a laboratory determination and without practical value. However, it led to the development of the modern sugar industry, when Franz Karl Achard, a pupil of Marggraf, attacked the problem of beet-root cultivation and succeeded in extracting sugar from beets on a greater scale.  read more button more


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)

gravestone icon  Died 3 Mar 2004 at age 88 (born 9 Feb 1916).
Portuguese ornithologist and conservationist who gave his name to Zino's petrel, Europe's rarest breeding bird. Only perhaps 45 mating pairs of the Zino's petrel (Pterodroma madeira) remain on the island of Madeira, south-west of Portugal, where this small black and white seabird breeds. The abundance population of the bird started to decline with the arrival of settlers (1419). By mid-20th century it was thought extinct. Zino, a successful businessman and native of Madeira, devoted much of the second half of his life to conservation. After searching, he re-discovered a small colony of the bird, in Jun 1969. Therafter, he studied and protected it. Zino's petrel continues to raise young in burrows on remote precipices of the mountains of Madeira.
  Gerhard Herzberg
gravestone icon  Died 3 Mar 1999 at age 94 (born 25 Dec 1904).
German-Canadian physicist who was awarded the 1971 Nobel Prize for Chemistry "for his contributions to the knowledge of electronic structure and geometry of molecules, particularly free radicals." He published his first work in molecular spectroscopy at the end of the 1920's. His measurement of how molecules absorb ultraviolet and infrared energy yield information on energy states in molecules, leading to knowledge of their size, shape and other properties. For example, he showed that radicals can drastically change their shape with increasing energy, such as methylene which is linear in its ground state but bent in higher energy states. He also applied spectroscopy in astronomy, identifying molecules in space, planetary atmospheres and comets.«

Polish-American physician and microbiologist best known for developing the first oral polio vaccine (1955), which was administered to millions of children in Europe, Africa, and the Americas beginning in the late 1950s. He was also known for his research in the fields of human viral diseases, toxoplasmosis, and cancer.
  William Penney
gravestone icon  Died 3 Mar 1991 at age 81 (born 24 Jun 1909).
(Baron Penney of East Hendred) British nuclear physicist who led Britain's development of the atomic bomb. Penney was to Britain as Robert Oppenheimer was to the U.S. He was a prominent part of the British Mission at Los Alamos during WW II, where his principal assignment was studying the damage effects from the blast wave of the atomic bomb, but he became involved in implosion studies as well. Penney's combination of expertise, analytical skill, effective communication, and the ability to translate them into practical application soon made him one of the five members of the Los Alamos “brain trust” that made key decisions. He was the only Briton to be part of the ten man Target Committee that drew up the list of targets for the atomic bombing of Japan.
  Charlotte Moore Sitterly
gravestone icon  Died 3 Mar 1990 at age 91 (born 24 Sep 1898).
American astrophysicist who organized, analyzed, and published definitive books on the solar spectrum and spectral line multiplets. From 1945 to age 90, she conducted this work at the U.S. National Bureau of Standards and the Naval Research Laboratory. She detected that technetium, an unstable element (previously known only as a result of laboratory experiments with nuclear reactions) exists in nature. She made major contributions to the compilation of tables for atomic-energy levels associated with optical spectra, which are now standard reference material. As instruments carried in space rockets provided new data in the ultraviolet, she extended these tables beyond the optical range. She was awarded the Bruce Medal in 1990.«

American geneticist who was one of the founders of modern theoretical population genetics. He researched the effects of inbreeding and crossbreeding with guinea pigs, and later on the effects of gene action on inherited characteristics. He adopted statistical techniques to develop evolutionary theory. Wright is best known for his concept of genetic drift, called the Sewell Wright effect - that when small populations of a species are isolated, out of pure chance the few individuals who carry certain relatively rare genes may fail to transmit them. The genes may therefore disappear and their loss may lead to the emergence of new species, although natural selection has played no part in the process.«

  Iosif Samuilovich Shklovskii
gravestone icon  Died 3 Mar 1985 at age 68 (born 1 Jul 1916).
Iosif Samuilovich Shklovskii was a Soviet astrophysicist who identified the continuum radiation of the Crab Nebula as synchrotron radiation, and he linked x-ray stars to binary systems containing a neutron star. His investigation of the corona of the sun showed it had a temperature of the order of a million kelvin, and that magnetic fields act to confine it. He applied radio astronomy to study supernovae. Mass extinctions on earth, he suggested, may have resulted from the cosmic rays ejected from past supernovae happening at relatively close range to our solar sytem. He was awarded the 1972 Bruce Medal. Shklovskii was one of the earliest well-respected astrophysicists to regard the possibility of extraterrestrial life as worthy of consideration. His popular books include Intelligent Life in the Universe (English translation by Carl Sagan).«

  Edmund Beecher Wilson
gravestone icon  Died 3 Mar 1939 at age 82 (born 19 Oct 1856).  quotes button quotes
American biologist known for his researches in embryology and cytology. His first experimental studies, in embryology, led him to investigations at the cellular level. His principal work was on the function of the cell in heredity and showed the chromosomal basis of sex determination in the embryo (1905). Wilson concluded that females have XX chromosomes, while males possess XY chromosomes. Following the process of meiosis, all eggs are left with an X chromosome, but sperm can have either X or Y. If an X chromosome sperm fertilizes an egg, the result is a female. If a Y chromosome sperm fertilizes and egg, the result is a male. He was the first scientist to publish photographs illustrating how a cell divides.
  William Kingdon Clifford
gravestone icon  Died 3 Mar 1879 at age 33 (born 4 May 1845).  quotes button quotes
British philosopher and mathematician who developed the theory of biquaternions (a generalization of the Irish mathematician Sir William Rowan Hamilton's theory of quaternions) and then linked them with more general associative algebras. In 1870, he survived a shipwreck near Sicily while on an expedition to Italy to obtain scientific data from an eclipse. Influenced by the work of Riemann and Lobachevsky, Clifford studied non-euclidean geometry. In 1870 he wrote On the Space Theory of Matter in which he argued that energy and matter are simply different types of curvature of space. In this work he presented ideas which were to form a fundamental role in Einstein's general theory of relativity.

gravestone icon  Died 3 Mar 1855 at age 73 (born 12 Aug 1781).
American architect and engineer who designed the Washington Monument in Washington, D.C. Mills also designed buildings in several Eastern states. In 1836, he won the competition for the design of the Washington Monument. Construction began in 1848 and proceeded slowly because of a lack of funds. The monument was only 152-ft high when Mills died in 1855; only in 1878 did Congress appropriate money to complete the structure, which was finished at 555-ft in 1884. He also designed the Department of Treasury building and several other federal buildings. His diverse interests included mapping and making a directory of lighthouses. He adopted fire-proofing measures in the design of buildings.«

  Johann Christian Fabricius
gravestone icon  Died 3 Mar 1808 at age 63 (born 7 Jan 1745).
Danish entomologist who was one of the great entomologists of the 18th century. After studying with Swedish naturalist Linnaeus, Fabricius travelled widely in Europe to see insect collections and produced many publications describing all the new species that he saw. He named and classified some 10,000 species of insects. The system of classification of insects he developed was based on mouth structure (instead of wing). He offered theories, progressive for his time, suggesting that hybridization could produce produce new species or varieties, and that environmental adaptation could influence changes in anatomical structure or function.
  William Stukeley
gravestone icon  Died 3 Mar 1765 at age 77 (born 7 Nov 1687).
English antiquary and physician whose studies of the monumental Neolithic Period-Bronze Age stone circles at Stonehenge and Avebury, Wiltshire, led him to elaborate extravagant theories relating them to the Druids (ancient Celtic priest-magicians). These views were widely and enthusiastically accepted in the late 18th century. Despite his romantic theorizing, he was an excellent field archaeologist, and his surveys of the monuments in the 1720s remain of interest. Stukeley was the first to note the midsummer alignment at Stonehenge, and the first to describe the Stonehenge and Beckhampton "Avenues" (his name, as were "Cursus" and "trilithon").Main representative of the theory of electricity as the cause of earthquakes in Britain.

English physicist who discovered the law of elasticity, known as Hooke's law, and invented the balance spring for clocks. He was a virtuoso scientist whose scope of research ranged widely, including physics, astronomy, chemistry, biology, geology, architecture and naval technology. On 5 Nov 1662, Hooke was appointed the Curator of Experiments at the Royal Society, London. After the Great Fire of London (1666), he served as Chief Surveyor and helped rebuild the city. He also invented or improved meteorological instruments such as the barometer, anemometer, and hygrometer. Hooke authored the influential Micrographia (1665).« [Image left: from a recently discovered portrait, believed (by Lisa Jardine) to be the only authentic picture of Hooke.

  Matthias de L'Obel
gravestone icon  Died 3 Mar 1616 (born 1538).
French physician and botanist whose Stirpium adversaria nova (1570; written in collaboration with Pierre Pena) was a milestone in modern botany, a collection of notes and data on 1,300 plants that he had observed and gathered in France and England. In this book, he argued that botany and medicine must be based on thorough, exact observation. L'Obel divided plants according to the form of their leaves. His two professions were closed related, as most medicines derived from plants. Thus, l'Obel managed several gardens of herbs, and wrote on them. The popular garden perennial Lobelia was named by Linneaus for him. (De l'Obel is French for "of the white poplar" and his family coat of arms was a poplar leaf.)

The New York Steam Corporation, formed 26 Jul 1880, consolidated with the Steam Heating and Power Company of New York on 19 Sep 1881. The plant, built on the block bounded by Cortlandt, Dey, Greenwich and Washington Streets had a 225-ft high chimney, and generated steam from 48 boilers each rated 250-h.p. By nine months later, the output served 62 customers.*«
  U.S. Geological Survey
calendar icon   In 1879, the office of director of the U.S. Geological Survey was authorized by Congress (20 Stat. L. 394), which made appropriations "for sundry civil expenses of the government." Clarence King, the first director, was nominated on 21 Mar 1879 and started work on 24 May 1879. The Survey was national in scope for the classification of public lands and their geological structure, mineral resources, and products. The first geological survey financed by Congress was authorized by act of Congress on 28 Jun 1834 (4 Stat. L. 394) which provided $5,000 for a survey made by George William Featherstonhaugh of the land between the Missouri and Red Rivers. The earliest survey at state expense was made in 1830-33 by Massachussetts.« *
  Science Association
calendar icon   In 1863, the National Academy of Sciences was chartered in the U.S. as President Abraham Lincoln approved the Act of Congress which established it (12 Stat. L. 806). The Act stipulated that the Academy would “whenever called upon by any department of the Government, investigate, examine, experiment or report upon any subject of science or art.” The Academy would receive no compensation, but the actual expenses incurred for the Government's requirements were to be paid from appropriations. In 1863, Alexander Dallas Bache became its first president, who served until 1867. Several scientific societies were formed in the U.S. before this date, the earliest being the Boston Philosophical Society founded in 1683.*« [Image: Details from 1924 portrait made for the dedication of the Academy Building, showing Founders at signing of the charter (top L to bottom R) Peirce, Bache (first president of the Academy), Henry, Agassiz, President Lincoln, Sen.

  First Black-American patent
calendar icon   In 1821, the first U.S. patent issued to a Black-American was granted to Thomas Jennings for a “dry-scouring”cleaning process (3 Mar 1821 No. X3306). Jennings used his royalties to buy his family out of slavery and to support the abolition of slavery. In 1831, Thomas Jennings became assistant secretary for the First Annual Convention of the People of Color in Philadelphia, Pennsylvania. For some time Henry Blair had been regarded as the first Black-American receiving a patent, for a corn planter (14 Oct 1834, No. X8447), until it became better known that the Jennings held that distinction.
