American forensic anthropologist who examined and identified the skeletons of a number of historical figures, including Tsar Nicholas II and other members of the Romanov family killed in 1918 by the Bolsheviks, Vietnam MIAs, conquistador Francisco Pizarro, and in 1994 helped convict Byron De La Beckwith of the 1963 murder of civil rights leader Medgar Evers. At the University of Florida, the C.A. Pound Human Identification Laboratory was created through Maples' energetic fundraising. This sophisticated, unique facility, dedicated to forensic anthropology opened its doors in 1986. Maples wrote Dead Men Do Tell Tales (1994, with Michael Browning). |

M(onkombu) S(ambisivan) Swaminathan is an Indian geneticist and international administrator, renowned for his leading role in India's "Green Revolution," a program under which high-yield varieties of wheat and rice seedlings were planted in the fields of poor farmers. He now recognises the need for an "Evergreen Revolution" to extend the benefits of development to the most marginalised. His work in crop genetics and sustainable agricultural development in India and the Third World earned him the first World Food Prize in 1987, among other awards. |

Louis S(eymour) B(azett) Leakey, an archaeologist and anthropologist, was born in Kabete, Kenya, of English missionaries parents. Leakey was largely responsible for convincing scientists that Africa, rather than Java or China, was the most significant area to search for evidence of human origins. Leakey led fossil-hunting expeditions to eastern Africa from the 1920's. He married Mary D. Nicol in 1936 and the couple discovered many important fossils together. In 1964, on an expedition to the Olduvai Gorge in Tanzania, he found fossil remains of, he believed, the earliest member of the genus of human beings. He named the species Homo habilis. |

(Louis) Alan Hazeltine was an American electrical engineer and physicist who invented the neutrodyne circuit, which made commercial radio possible. As one of the few experts in radio engineering at the outbreak of WW I, he designed a radio receiver for the U.S. Navy. In 1922, Hazeltine invented the "neutrodyne" receiver to eliminate the squeaks and howls of the early radio receivers, using neutralizing capacitors to in effect siphon off the high pitched squeals. The Hazeltine amplifier neutralized the grid-to-plate capacitative coupling which was a cause of oscillation in triode amplifiers. The neutrodyne was the first commercial receiver suited to general public reception. By 1927 some ten million of these receivers were being used by listeners in the U.S. |
| Philipp Forchheimer | |
Austrian hydraulic engineer who made significant studies of groundwater hydrology. Early in his academic career, he worked on problems of soil mechanics. Later, he turned to hydraulic problems, establishing the scientific basis of the discipline by applying standard techniques of mathematical physics - in particular Laplace's equation - to problems of groundwater movement. Laplace's equation had already been well developed for heat flow and fluid flow. Forchheimer extended the preexisting mathematical theory to calculations of groundwater flow. He was also the first to both mathematically and experimentally examine the features of dambreak waves in a rectangular channel (with his PhD student Armin Schoklitsch).« |

Auguste Michel-Lévy was a French geologist and mineralogist who was a pioneer in microscopic petrology, the study of the origin, composition, structure, and alteration of rocks. He was particularly interested in rocks of volcanic origin. He was the first scientist in France to examine thin slices of rock with a polarizing microscope to identify the mineral content. In his published papers, he described the granulite group, and dealt with pegmatites, variolites, eurites, the ophites of the Pyrenees, the extinct volcanoes of Central France, gneisses, and the origin of crystalline schists. He became inspector-general of mines, and in 1870 joined the Geological Survey of France, becoming its director in 1887.« |
| Germain Henri Hess | |
(source) |
Swiss-born Russian chemist whose studies of heat in chemical reactions formed the foundation of thermochemistry. He formulated an empirical law, Hess's law of constant heat summation (1840), which states that the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps. It is explained by thermodynamic theory, which holds that enthalpy is a state function. Chemists have made great use of the law of Hess in establishing the heats of formation of compounds which are not easily formed from their constituent elements. His early investigations concerned minerals and the natural gas found near Baku, and he also discovered the oxidation of sugars to yield saccharic acid. |
| John Heathcoat | |
(EB) |
Pioneering English inventor of lace-making machinery. As a boy, Heathcoat made stockings and became familiar with the machines and used this knowledge to develop and patent his lace net machine (1809) which was capable of the intricate, complicated motions and delicate operations needed to produce lace. His machines made lace hundreds of times faster than it could be manufactured by hand. He established a company in 1808 and based his original factory in Nottingham. However in 1816, the Luddites burnt down the factory and destroyed most of his machines, and so he relocated the company to Tiverton, Devon, where he had previously purchased an old woollen mill on the banks of the River Exe.

English military engineer who constructed the 126-mile (202-km) Rideau Canal connecting the Ottawa River and Lake Ontario, Canada, which was originally intended as a military supply route. It was designed to provide an alternative to the St. Lawrence River route which was vulnerable in case of war with the U.S., which was seen as a possibility after the American Revolution. Work began in 1826 near the junction of the Ottawa and Rideau rivers. Engineering challenges included an arched dam at Jones Falls with four locks with a total lift of 60 feet (three locks, a turning basin and a fourth lock). When the waterway was opened in Spring 1832, Lt. Col. By returned to England. The settlement that grew at the canal's mouth, at first known as Bytown, was named Ottawa in 1855, and is now the nation's capital.« |
| James Bowdoin | |
![]() |
American founder and first president of the American Academy of Arts and Sciences (1780). He was a scientist prominent in physics and astronomy, and wrote several papers including one on electricity with Benjamin Franklin, a close friend. In one of his letters to Franklin, Bowdoin suggested the theory, since generally accepted, that the phosphorescence of the sea, under certain conditions, is due to the presence of minute animals. Bowdoin was also a political leader in Massachusetts during the American revolution (1775-83), and governor of Massachusetts (1785-87). His remarkable library of 1,200 volumes, ranged from science and math to philosophy, religion, poetry, and fiction. He left it in his will to the Academy. |

Bart Jan Bok was a Dutch-American astronomer whose name remains associated with the "Bok globules" he was the first to investigate - dark clouds of dense gas and dust visible against a background of bright nebulae. Bok globules have a mass of 10 to 50 times the mass of the Sun and are about a light year across. He began their observation in the 1940's and in a 1947 paper with E.F. Reilly proposed that these were sites of new star formation as the gas clouds underwent gravitational collapse. Bok's other important work was on the structure and evolution of the Milky Way Galaxy. His enthusiasm for astronomy began as a young boy. Bok bicycled to Norway to observe the solar eclipse of 1927. He moved to the U.S. in 1929.« |
| Karl S. Lashley | |

Karl Spencer Lashley was an American psychologist who conducted quantitative investigations of the relation between brain mass and learning ability. He collaborated with Shepherd J. Franz in the study of intelligence and the role of the frontal lobes. Lashley promulgated the theory of cortical specialization for sensory and motor functions. He challenged the ongoing concept of cortical localization. The controversy between localization and holistic emphasis of brain function was brought into focus by Lashley. He is remembered as a great psychologist who approached learning and memory by assessing the effects of brain damage in laboratory animals. |
| Herbert Osborne Yardley | |
(source) |
American cryptographer who organized and directed the U.S. government's first formal code-breaking efforts during and after World War I. He began his career as a code clerk in the State Department. During WW I, he served as a cryptologic officer with the American Expeditionary Forces in France during WWI. In the 1920s, when he was chief of MI-8, the first U.S. peacetime cryptanalytic organization, he and a team of cryptanalysts exploited nearly two dozen foreign diplomatic cipher systems. MI-8 was disbanded in 1929 when the State Department withdrew funding. Jobless, Yardley caused a sensation in 1931 by publishing his memoirs of MI-8, The American Black Chamber, which caused new security laws to be enacted. |
| James Hall | |
(source) |
U.S. geologist and paleontologist who is considered one of the founders of American geology. He invented the term geosyncline and the geosyncline theory for mountain building, which proposed that as sediment is increasingly deposited in a shallow basin, the basin will sink, causing the adjacent area to rise. (This was superseded in the 1960's by the new theories of Plate Tectonics.) In paleontology, he studied the Silurian and Devonian fossils (345 million - 430 million years old) found in New York, and recorded his results in a 13-volume series, The Paleontology of New York (1847-94). Hall was a charter member of the Academy of Sciences.« |

Jöns Jacob Berzelius was a Swedish scientist, one of the founders of modern chemistry. He is especially noted for his determination of atomic weights, the development of modern chemical symbols, his electrochemical theory, the discovery and isolation of several elements, the development of classical analytical techniques, and his investigation. |
| Joseph Marie Jacquard | |
engraving 1874 (EB) |
French silk weaver, (born Lyons), inventor of the Jacquard programmable power loom for brocaded fabric. His loom would mechanically produce any pattern, controlled by perforated control cards (1805). This served as the impetus for the technological revolution of the textile industry and is the basis of the modern automatic loom. The concept of using punched cards was later applied by Hollerith to keeping track of the 1890 US census data. The idea further evolved to computer input punched cards. |
