1952 (source) |
English archaeologist who, between the wars, dominated a string of pioneering excavations in the Near East (1929-34), most notably the 22 month excavation at Mount Carmel, Palestine, which put Near Eastern prehistory on the map. The Mount Carmel cave deposits spanned 200,000 years of human occupation, and finds included over 92,000 stone tools. Most important were the finds of human fossils, including the skeleton of a female Neanderthal dated c. 110,000 BC, the first ever to be found outside Europe. This led on to the discovery of more skeletal remains of primary importance to the study of human evolution. A leading authority on the Paleolithic for many years, Garrod was the first woman to receive a professorship at the University of Cambridge (1939-52). |

American electrical engineer who invented the mercury-vapour lamp, an important forerunner of fluorescent lamps. He studied the production of light using electrical discharges (while Edison was still developing incandescent filaments). The mercury-filled tubes he developed from the late 1890s, gave off an unattractive blue-green light. Although unsuitable in homes, its brilliance won wide adoption by photo studios because the black and white film of the time needed just bright light, despite its colour. There were many other industrial uses for the lamp. His manufacturing company (est. 1902) was bought by General Electric in 1919 which produced a new design in 1933. He took out his first eight mercury vapour lamp patents on 17 Sep 1901.« |
| Ferdinand Paul Wilhelm Richthofen | |
(Baron) German geographer and geologist who produced a major work on China and contributed to the development of geographical methodology. He also helped establish the science of geomorphology, the branch of geology that deals with land and submarine relief features. |

Canadian geologist and paleontologist, who was the first Canadian paleontologist. For three years as the editor of the Ottawa Citizen, he wrote a series of articles on science, including geology and paleontology. He published his first scientific paper on Trenton fossils in 1854. He launched a new monthly periodical, The Canadian Naturalist and Geologist in 1856, which he also edited and was the major contributor. In Aug 1856 he was appointed staff paleontologist with the Canadian Geological Survey by William Edmond Logan, the founder of the Survey. Billings immediately began the task of identifying a 20-year backlog of fossils collected by the Survey. By 1863 he had published descriptions of no fewer than 526 new species of fossils. |
| John William Draper | |

English-American chemist who pioneered in photochemistry. He recognized that light initiated chemical reactions as molecules absorbed light energy. The Draper Point is the name given to the point at which all substances glow a dull red (about 525 degrees C.). He described the effect of rise in temperature as the addition of more and more of the visible light region produced a white glow (1847). His interest in spectroscopy and photography was applied to give the first atronomical photograph. Its subject was the moon (1840). He also studied photographs of the solar spectrum to show that contained both infrared and ultraviolet light. His photographs of persons include the oldest surviving photgraphic portrait (1840), and he was one of the first to produce microphotographs. |

Theodore H(arold) Maiman was an American physicist who built the first working laser. He began working with electronic devices in his teens, while earning college money by repairing electrical appliances and radios. In the 1960s, he developed, demonstrated, and patented a laser using a pink ruby medium. The laser is a device that produces monochromatic coherent light (light in which the rays are all of the same wavelength and phase). The laser has since been applied in a very wide range of uses, including eye surgery, dentistry, range-finding, manufacturing, even measuring the distance between the Earth and the Moon. |
| Sir Alastair Pilkington | |
Sir Lionel Alexander Bethune Pilkington was a British industrialist and inventor of the float glass process. |

| Tom Blake | |
American inventor of the hollow-core surfboard. Following his first experimental hollow surfboard in 1926, his innovative, hollow-core surf/paddle boards dominated the surfing world until the late 1940's. It became standard rescue equipment in California's early lifeguard corps. Early surfboard designs consisted of solid wooden boards dating back to the ancient Hawaiians, these new-concept, lighter boards were an immediate success and became extremely important in the evolution of the modern surfboard. In the 1930's he made the first major design advancement with the invention of fins. Before this, a surfer had to use his back foot to make the board turn. Many early Blake boards are displayed at the Bishop Museum, Honolulu. |

American scientist, one of four co-discoverers of plutonium, (element 94) which was produced from uranium oxide bombarded with deuterons in a cyclotron at the Univ. of California at Berkeley. Subsequently, on 28 Mar 1941, Glenn Seaborg, Emilio Segrè and Joseph Kennedy demonstrated that plutonium, like U235, is fissionable with slow neutrons, thus neutrons of any speed, which implies it's a potential fission bomb material. He was a chemistry instructor while working on the research project led by Glenn Seaborg at the University of California, Berkeley. After working with Seaborg, Kennedy was chosen by J. Robert Oppenheimer to lead the Chemistry Division of the Manhattan Project. Image: plutonium hydroxide, 20 microgram in a capillary tube, 1942. |

English photographer and inventor who built and patented an early somewhat practical motion picture camera (21 Jun 1889, No. 10,131). From about 1875, he operated a portrait photography studio. He experimented with motion photography. An early attempt was a camera able to take 10 images per second on a roll of sensitized paper. Later he used celluloid film. He claimed perhaps the first time a film of an actual event was ever projected on a screen - a jerky picture of people and horse-drawn vehicles moving past Hyde Park Corner. Although he held and defended patents, his inventions were less significant than those developed by others. The first functional movie camera is generally credited to Frenchman Etienne-Jules Marey in 1888.« |

British explorer and archaeologist who excavated the magnificent Iron Age ruined city named the Great Zimbabwe, an ancient site in SE Africa that inspired the name of the country Zimbabwe (formerly Rhodesia). The word Zimbabwe traces to the Bantu dzimbahwe; i.e., stone houses, or chiefs' graves. The earliest habitation is dated to about 400 AD, with inhabitation by Shona cattleherders from about 500 AD. Between the 12th to 15th centuries, stone structures still visible were built. The site lies within the Victoria region of modern state of Zimbabwe, which lies between the Zambezi and Limpopo Rivers. The outer elliptical wall measures 830-ft circumference, varied height, up to 40’ and up to 17-ft thick. |
| Peter Gustav Lejeune Dirichlet | |
(source) |
German mathematician who made valuable contributions to number theory, analysis, and mechanics. Dirichlet is best known for his papers on conditions for the convergence of trigonometric series and the use of the series to represent arbitrary functions. He also proposed in 1837 the modern definition of a function. In mechanics he investigated the equilibrium of systems and potential theory. This led him to the Dirichlet problem concerning harmonic functions with given boundary conditions. Dirichlet is considered the founder of the theory of Fourier series, having corrected the earlier mistakes of other workers on Fourier's writings. One of his students was Riemann. In 1855, he succeeded Carl Friedrich Gauss at the University of Göttingen. |

French philosopher and physiologist noted for Rapports du physique et du moral de l'homme (1802; "Relations of the Physical and the Moral in Man"), which explained all of reality, including the psychic, mental, and moral aspects of man, in terms of a mechanistic Materialism. He argued that "to have an accurate idea of the operations from which thought results, it is necessary to consider the brain as a special organ designed especially to produce it, as the stomach and the intestines are designed to operate the digestion, (and) the liver to filter bile..." |
| Jean Nicot | |
(source) |
French diplomat who introduced tobacco to the French court. In 1560, while serving as ambassador in Portugal, he was shown a tobacco plant in the garden of Lisbon botanist Damião de Goes, who claimed it had healing properties. Nicot sent home seeds and leaves of tobacco, recommending its marvelous therapeutic value. He had applied it to his nose and forehead and found it relieved his headaches. Nicot sent snuff to Catherine de Medici, the Queen of France to treat her migraine headaches. She was impressed with its results. The tobacco plant, Nicotiana tabacum, and its active substance, nicotine, derive their names from his. He also compiled one of the first French dictionaries, Thresor de la langue françoyse (1606).« |
