Hungarian-American biochemist who was awarded the 1937 Nobel Prize for Physiology or Medicine “for his discoveries in connection with the biological combustion processes, with special reference to vitamin C and the catalysis of fumaric acid.” He isolated the vitamin C (ascorbic acid), noted its value for preventing scurvy, and extracted quantities of it from Hungarian paprika. He also investigated biological oxidation and recognized the catalytic function of the C4-dicarboxylic acids and discovered flavin. In 1938 he began work on muscle research and shortly discovered the proteins actin and myosin and their complex.«

(née Danielsen) German-born American psychoanalyst who departed from some of the basic principles of Sigmund Freud, suggesting that environmental and social conditions, rather than biological drives, determine much of individual personality and are the chief causes of neuroses and personality disorders. While she recognized the importance of early childhood experiences in determining neurotic conflicts, she contended that the analyst must also be aware of current fears and impulses. She also stressed the necessity of understanding the environmental context in which neurotic conflicts are expressed. Her view of human beings allowed much more scope for development and rational adaptation than Freudian determinism permitted.

American inventor and manufacturer of the first successful electric dry razor. He started in the razor business in 1925 to design and manufacture his invention of the Magazine Repeating Razor. By 1926, he was selling clips of blades that could be loaded into a safety razor without touching the blade to avoid cuts during handling. While this product was successful, he turned his attention to developing a dry razor. By 1927 he had designed a dry razor with a reciprocating head powered by a flexible drive shaft to an external motor. Although he marketed this model from 1929, it was not until 1931 that he had improved the idea as a new one-handed electric shaver with self-contained motor that sales took off. He lived only six year after that.«.

American geologist, climatologist, explorer and geographer who studied the origin, distribution, longevity, and accomplishments of civilization. He particularly wished to understand why progress varied from times when human creative energies flourished to periods when they seemed to fade. He attributed this to three causes: climate, the quality of people, and culture. Climatic circumstances resulted in migration, which could either facilitate or obstruct the advance of culture.

U.S. civil engineer, inventor, and theoretician who provided the first scientifically based rules for bridge construction, was considered one of the top engineers of the 19th Century, and was known as the "father of iron bridges." He began his career as a bridge-builder in 1840 by designing and patenting an iron-bridge truss. During the next ten years he built several bridges on the Erie canal and the New York and Erie railroad. His design of the Whipple truss bridge was the model for hundreds of bridges that crossed the Erie Canal in the late 19-th century. Before developing his design, Whipple worked for several years on surveys, estimates, and reports for the enlargement of the Erie Canal, and in 1840 he patented a scale for weighing canal boats. He later built the first weighing lock scale constructed on the Erie Canal. The invention of the steam engine required bridges which could support heavy live loads and this motivated Squire to turn his attention to bridges. In 1853, he completed a 146-ft span iron railroad bridge near West Troy (now Watervliet), N.Y. His book on the design of bridges using scientific methods (1847) was the first of its kind. The formulas and his methods are still useful. He obtained a patent for his lift draw-bridge in 1872.[Image: Bowstring Truss designed by Squire Whipple. This rare cast-and wrought iron bridge, built in 1872, was located in Coshocton County, Ohio, crossing Wills Creek on Linton Township Road 144.]

French physician and clinician who first discovered the localisation of the speech centre in the middle of the left cerebral hemisphere of the brain. He reported this observation in 1825 in his early treatise on brain diseases. He also presented clinical evidence that loss of speech corresponds to a lesion of the anterior lobes of the brain, confirming Gall's opinion on the seat of the organ of articulate language. As a clinician, he published on diverse fields of medicine, including hermaphroditism, on cholera, encephalitis, diseases of the heart, cancer and various forms of fever. In his significant work on rheumatism he recognised the cartilaginous and synovial lesions of this disease and was the first to describe them.«

French geologist and geographer whose discovery of the volcanic origin of basalt disproved the Neptunist theory that all rocks were formed by sedimentation from primeval oceans. Studying the Auvergne of central France (1763-74), he found large basalt deposits that he traced as lava flows from nearby ancient volcanoes. He further showed that many valleys are formed by the erosion of the rivers that flow in them. From 1757, Desmarest was employed by the government to help spread better manufacturing methods throughout France. By 1788 he had risen to the post of inspector general and director of manufactures. In 1792, during the French Revolution, Desmarest was imprisoned and narrowly escaped execution.Image: Basalt rock of the Devil's Tower, Wyoming, USA, is an ancient volcanic intrusion left over after all of the overlying material has been eroded away.

For this discovery he became the first British Nobelist, when he was awarded the 1902 Nobel Prize for Physiology or Medicine. His study of malaria began in 1892. By 1894 he conducted experiments in India to determine the validity of the hypothesis of Alphonse Laveran and Patrick Manson that mosquitoes spread the disease. It took two and a half years' effort before Ross succeeded in elucidating the life-cycle of malarial parasites in mosquitoes. In later work, in West Africa, he also determined the mosquito species carrying the deadly African fever.« more

Army Surgeon-General Sternberg assigned Carroll to the medical faculty of the Army Medical Museum in Washington, where he and Walter Reed worked together in bacteriology research. In 1899, Sternberg appointed Carroll and Reed to investigate the bacillus icteroides, the microbe that Italian bacteriologist Giuseppe Sanarelli had identified as the cause of yellow fever. Their work helped disprove Sanarelli's theory and catapulted Carroll and Reed into the yellow fever debate. In 1900, Carroll was promoted to Acting Asst. Surgeon in the Army Medical Corps and placed him second-in-command on the Yellow Fever Commission with Reed as officer-in-charge.

American physician and scientist who financed two balloon flights for himself and a Frenchman, Jean Pierre Blanchard, with experience in balloon flight. Jeffries wished to make scientific and meteorological observations. The first flight took place in London on 30 Nov 1784. Jeffries had provided himself with thermometer, barometer, electrometer, hygrometer and timepiece. He took air samples at different elevations for Cavendish, who subsequently made a chemical analysis of the air. The twelve observations of temperature, pressure, and humidity that Jeffries made were the first scientific data for free air, to a height of 9,309 feet. The values agree closely with modern determinations. On 7 Jan 1785, they made the first balloon crossing of the English Channel.Image: Jeffries posed as if in balloon, holding barometer.

Jeffries wished to make scientific and meteorological observations. The first flight took place in London on 30 Nov 1784. Jeffries had provided himself with thermometer, barometer, electrometer, hygrometer and timepiece. He took air samples at different elevations for Cavendish, who subsequently made a chemical analysis of the air. The twelve observations of temperature, pressure, and humidity that Jeffries made were the first scientific data for free air, to a height of 9,309 feet. The values agree closely with modern determinations. On 7 Jan 1785, they made the first balloon crossing of the English Channel.Image: Jeffries posed as if in balloon, holding barometer.

Gabriel Daniel Fahrenheit was a German-Dutch physicist and instrument maker (meteorological). He lived in Holland for most of his life. He invented the alcohol thermometer (1709) and mercury thermometer (1714) and developed the Fahrenheit temperature scale. For the zero of his scale he used the temperature of an equal ice-salt mixture; 30° for the freezing point of water; and 90° for normal body temperature. Later, he adjusted to 32° for the freezing point of water and 212° for the boiling point of water, the interval between the two being divided into 180 parts. He also invented a hygrometer to measure relative humidity and experimented with other liquids discovering that each liquid had a different boiling point that would change with atmospheric pressure.

In 2011, President Obama signed the America Invents Act which made substantial changes to the U.S. patent system. Effective 16 Mar 2013, only the “first-to-file” inventor had priority, eliminating claims by others of being the first to invent an invention. “Prior art,” used to exclude patentability, was expanded to include public use, sales including foreign offers for sale, publications and disclosures available to the public anywhere in the world as of date of filing. Previously, for example, when William Kelly asserted he was first to invent his “air-boiling” process to refine steel, he was awarded U.S. patent priority (23 Jun 1857) over Henry Bessemer, even though Bessemer filed first.«

Antartic ozone hole, Sep 2000
In 1987, the “Montreal Protocol on Substances that Deplete the Ozone Layer” was signed, agreeing to phase out by 2000, the production and consumption of man-made compounds known to deplete ozone in the stratosphere. Subsequent meetings (1990-97) refined and amended the protocol. Because of their relatively high ozone-depletion potential, in addition to chlorofluorocarbons (CFCs), other man-made compounds—carbon tetrachloride, methyl chloroform, and halons—were the first targets for phaseout. Now, the U.S. Clean Air Act, for example, bans the release of ozone-depleting refrigerants during the maintenance or disposal of air conditioners and other refrigeration equipment.«
In 1908, former carriage-maker William Crapo "Billy" Durant founded General Motors (GM) by incorporating with a capital of $2,000 and was the man responsible for the beginning of the huge auto manufacturing company. Within 12 days the company generated stocks that generated $12,000,000 cash. On 29 Sep 1908, GM bought Buick. Later, GM bought Oldsmobile in Lansing, Cadillac in Detroit, and Oakland in Pontiac. Durant lost control of the company in 1910. He had originally started in business by partnering with Josiah Dallas Dort in 1886 to purchase the Coldwater Road Cart Company. By 1890, Durant-Dort Carriage Company was the nation's largest carriage company, producing approximently 150,000 vehicles a year.
Koller
In 1884, cocaine was first used as a local anaesthetic to immobilize a patient's eye for eye surgery by Carl Koller. His success initiated the modern era of local anesthesia, with cocaine also quickly adopted for nose and throat surgery and for dentistry. For Koller, a Czech-born American ophthalmologist, the clue for this use was when he noticed that cocaine had a numbing effect on the tongue. He made many experiments on animals before introducing its use on humans. Cocaine was isolated in 1859 and was synthesized in 1885. It was later found with high doses or repeated use, it caused erosion of the corneal epithelium in high doses and it was replaced by less toxic, synthetic local anesthetics such as tetracaine and proparacaine.«
In 1835, British naturalist Charles Darwin, aboard the ship HMS Beagle, arrived at the Galapagos archipelago, a cluster of islands on the equator 600 miles west of South America. During his five weeks studying the fauna in the Galapagos, Darwin found the giant tortoises there greatly differed from one another according to which island they came from. Moreover, many islands developed their own races of iguanas. These observations contributed to his theory of “natural selection,” that species evolved over thousands of millions of years.
In 1774, Antoine Lavoisier observed that heating mercuric oxide produces metallic mercury. He thought the reaction might have been caused by contact with iron; he made no note of gas evolution in his notebook.
Flamsteed
In 1662, the first recorded astronomical observation of the first Astronomer Royal was John Flamsteed's observation of a solar eclipse from his home in Derby at the age of sixteen, about which he corresponded with other astronomers. Flamsteed's interest in astronomy was stirred by the solar eclipse, and besides reading all he could find on the subject he attempted to make his own measuring instruments.
