| Wilhelm Schmidt | |
(source) |
German anthropologist was a Roman Catholic priest whose research focussed on the origin of the idea of God and religion within various cultures, trying to link what emerged from ethnological studies with what is stated in the Bible. Schmidt proposed theories on the effect of environment in the evolution of families. He extensively studied ethnography particularly “culture circles,” a series of four main stages that the base cultures of this world went through: Primitive (hunter-gatherer), Primary (horticulturists), Secondary (pastoralists) and lastly Tertiary (modern society). Others had proposed such a theory earlier, but Schmidt's work increased its popularity and acceptance. He founded the journal Anthropos (1906).« |
| Henry Martyn Leland | |

American inventor and industrialist who founded Cadillac Motors (22 Aug 1902) to build the Cadillac, the first automobile with high-precision, fully-interchangable parts. Earlier in his life, he had learned precision toolmaking making rifles during the Civil War, invented the first mechanical barber's clippers, and made engines for Oldsmobiles. When Leland designed an improved engine, but Olds did not want to adopt it, Leland started Cadillac to build his own own brand of automobile. He eventually sold the company to Will Durant's General Motors Co. During WW I, he formed a new company to manufactured aircraft engines, which after the war he produced a new automobile: the Lincoln. That company was bought by Henry Ford.« |
| Ernst Haeckel | |
(source) |
German biologist who separated the animal kingdom into unicellar and multicellular organisms, and was an enthusiastic supporter of Darwin's theories. He led numerous scientific expedition, and cataloged 4,000 new species of lower marine animals. However, he held an erroneous concept, popularized an expression, "Ontogeny recapitulates phylogeny," (meaning that he supposed any animal embryo progresses through all previous evolutionary stages as it develops) which he based on the striking resemblance of the early embryos of many early vertibrate embryos. Such interpretation may not have lasted, but he nevertheless stimulated enquiry. He coined many words used by biologists today, such as ecology, phylum and phylogeny.« |
| Julius Thomsen | |

(Hans Peter Jörgen) Julius Thomsen was a Danish chemist who tabulated the amount of heat released or absorbed in 3,500 chemical reactions. He also prepared the first table of the relative strengths of acids. He became wealthy from his process (patented in 1853) for the fabrication of soda from the mineral cryolite. In 1878, Thomsen (and independently by Marcellin Berthelot) proposed that every chemical change proceeds in such a direction that it will produce the most heat. However, this statement is incorrect, for many exceptions are known in which chemical reactions are spontaneous even though they absorb heat. Thomsen designed the modern format of groups and periods on the long form of the Periodic Table of the Elements (1895)« |
| Sir Francis Galton | |
(source) |
English scientist, founder of eugenics, statistician and investigator of intellectual ability. He explored in south-western Africa. In meteorology, he was first to recognise and name the anticyclone. He interpreted the theory of evolution of (his cousin) Charles Darwin to imply inheritance of talent could be manipulated. Galton had a long-term interest in eugenics - a word he coined for scientifically selected parenthood to enable inheritance of beneficial characteristics. He coined the phrase "nature versus nurture." Galton experimentally verified the uniqueness of fingerprints, and suggested the first classification based on grouping the patterns into arches, loops, and whorls. On 1 Apr 1875, he published the first newspaper weather map - in The Times.« [Image: at age about 50] |

German zoologist who studied primarily invertebrates (such as jelly fish, intestinal worms, salamanders and freshwater fish) He also investigated life cycles of parasites and discovered the parthenogenesis of the honeybee (the development of an organism from an unfertilized egg). In 1848, with Koelliker, he created Zeitschrift für wissenschaftliche Zoologie (“Journal of Scientific Zoology”), which he edited until his death.« |
| Jean-Baptiste-Julien d' Omalius d'Halloy | |
(source) |
Belgian geologist who was an early proponent of evolution. From his youth he pursued geological researches. He was one of the pioneers of modern geology who determined the stratigraphy of the Carboniferous and other rocks in Belgium and the Rhine provinces, and also made detailed studies of the Tertiary deposits of the Paris Basin. As noted by Charles Darwin in the preface of Origin of the Species: "In 1846 the veteran geologist ... Halloy published ... his opinion that it is more probable that new species have been produced by descent with modification than that they have been separately created: the author first promulgated this opinion in 1831." Even in his ninety-first year Halloy made a scientific expedition alone, which exertion contributed to his death. |
| Pierre Bouguer | |

French physicist whose work founded photometry, the measurement of light intensity. He was a child prodigy, a professor at age 15, following his father, Jean Bouguer, in hydrography - the study of bodies of water, both salt and fresh. He participated on the expedition to Peru (1735-44) to measure an arc of the meridian near the equator. In 1729, he invented a photometer to compare the intensity of two light sources illuminating separate halves of translucent paper. The eye itself, he determined, could not be used as a meter, but could establish the equality of brightness of adjacent surfaces. He determined the sun was 300 times brighter the moon. Bouguer's law gives the attenuation of a beam of light by an optically homogeneous (transparent) medium.« |
| Georg Joachim Rheticus | |
(source) |
Austrian-born astronomer and mathematician who was among the first to adopt and spread the heliocentric theory of Nicolaus Copernicus. He was first taught by his father, a physician, who was beheaded for sorcery in 1528, while Rheticus was still a teenager. He is best known as the first disciple of Copernicus. In 1540, Rheticus published the first account of the heliocentric hypothesis which had been elaborated by Copernicus, entitled Narratio prima, which was explicitly authorised by Copernicus, who also asked for his friend's aid in editing the edition of his De revolutionibus orbium coelestium ("On the revolutions of the heavenly spheres"). Rheticus was the first mathematician to regard the trigonometric functions in terms of angles rather than arcs of a circle. |

American physician who teamed with his wife in researching the physical aspects of sexuality and produced some of the first reliable data in the field. He began researching sexual function at the Washington University School of Medicine in 1954. Virginia Eshelman Johnson joined him three years later. Human Sexual Response, their first book, was published for the medical community but became a best seller. Masters & Johnson Institute opened in 1964 to provide sex therapy and counseling based on their findings. Their research, books and media activities profoundly affected American society. The Institute closed in 1994 upon his retirement.« |
| Marie-Louise von Franz | |

German-born Swiss psychologist who was a Jungian analyst (1948-98) in collaboration with Carl Jung for over 30 years. She was also fairy-tale expert whose research showed common themes in tales from many cultures, which she linked with experiences in daily life. She began analysis with Jung at eighteen, and worked with him until his death in 1961. As Jung's primary partner in his research into alchemical texts, her first major publication, Aurora Consurgens, is a companion volume to Jung's last major work, Mysterium Cuniuntionis. Other works include On Dreams and Myths and C.G. Jung: His Myth in Our Time. |
| Chien-Shiung Wu | |
(source) |
Chinese-born American physicist who provided the first experimental proof (1956) that parity is not conserved in weak subatomic interactions of nuclear beta decay. When two physicists, Tsung-Dao Lee, and Chen Ning Yang proposed that parity was not conserved for weak interactions, Dr. Wu tested the proposal by observing the beta particles given of by cobalt-60. She observed that there is a preferred direction of emission, and that therefore, parity was not conserved for this weak interaction. In other words, Dr. Wu was able to prove that identical nuclear particles do not always act alike, and, thereby, disprove, what was then, a widely accepted "law" of nature. |
| Ernst Weber | |
(source) |
Austrian-born American electrical engineer who contributed to the development of microwave technology, applied in radar and communications systems. During WWII, he led researchers solving the problems of accurately measuring very high frequency microwaves, essential for the calibration of radar. (This involved learning how to coat glass tubes with a very thin layer of conducting metal, which Weber derived from the ancient skill of decorating chinaware with gold and silver, followed by success using a mixture of platinum and palladium.). The team created other designs and production techniques that helped the overall development of radar during the war. His expertise later guided the growth of the Polytechnic Institute in New York City.« |
| Edward Thomas Copson | |
Scottish mathematician known for his contributions to analysis and partial differential equations, especially as they apply to mathematical physics. |

| Peyton Rous | |
(source) |
American pathologist whose discovery of cancer-inducing viruses earned him a share of the Nobel Prize for Physiology or Medicine in 1966. Rous joined the Rockefeller Institute in New York as a pathologist in 1909. The same year, a local farmer brought a chicken with a tumour for testing. Having determined it to be a sarcoma, Rous discovered that it could be "transferred" into a healthy chicken by grafting tumour cells. Surprisingly, injecting cell-free filtrates from the tumour also led to sarcomas in healthy chickens. By 1914, Rous's laboratory had discovered three distinct types of avian sarcomas. Although he did not isolate specific agents, Rous postulated that chicken tumours were due to "filterable agents"-eventually identified as Rous sarcoma virus. |
| Sir John Sealy Edward Townsend | |
(source) |
British physicist who pioneered in the study of electrical conduction in gases. In 1898 he made the first direct measurement of the unit electrical charge (e). As a postgraduate, he was a research student of J. J. Thomson. In 1897, Townsend developed the falling-drop method for measuring e, using saturated clouds of charged water droplets (extended by Robert Millikan's highly accurate oil-drop method). He was first to explain how electric discharges pass through gases (Electricity in Gases, 1915) whereby motion of electrons in an electric field releases more electrons by collision. These in turn collide releasing even more electrons in a multiplication of charges known as an avalanche. |

![]() (Isaac) Leslie Hore-Belisha, 1st Baron Hore-Belisha (of Devonport), statesman and inventor of belisha beacons, the omni-present flashing orange globe lights at British pedestrian road crossings. During his term as Minister of Transport from 1934, the driving test was introduced and the Highway Code was rewritten, which combined with his beacons significantly reduced road accidents. He was Jewish, and particularly motivated to fight Nazi Germany when as British secretary of state for war (1937-40), he instituted military conscription in the spring of 1939, a few months before the outbreak of World War II. However, Chamberlain replaced him in Jan 1940, at a time when he had poor relations with the ministers and the War Cabinet.« [Image right: Belisha beacons at a pedestrian crossing] |
| Meghnad N. Saha | |
Indian astrophysicist noted for his development in 1920 of the thermal ionization equation, which, in the form perfected by the British astrophysicist Edward A. Milne, has remained fundamental in all work on stellar atmospheres. This equation has been widely applied to the interpretation of stellar spectra, which are characteristic of the chemical composition of the light source. |

French scientist and army general who contributed to the development of radio communication in France. He participated with Guglielmo Marconi in experimental wireless telegraphy (1899) between Paris, France and England. In 1903, Ferrié directed the installation of a transmitter and antennas on the Eiffel Tower in Paris for long-range radiotelegraphy. Within 5 years, he had improved its effective range from 400 km (250 miles) to 6,000 km (3,700 miles). This led him to develop mobile military transmitters to maintain radio contact with Paris. He also experimented with radio transmissions from aircraft to enable the aerial direction of artillery fire. Early in WW I, (Colonel) Ferrié led a corps of technicians who set up a network of radio direction finders. |
| H. W. Bates | |

H(enry) W(alter) Bates was a naturalist and explorer whose demonstration of the operation of natural selection in animal mimicry (the imitation by a species of other life forms or inanimate objects), published in 1861, gave firm support to Charles Darwin's theory of evolution. He and Alfred Russel Wallace left England in 1842 to explore and collect insects in the Amazon basin. Bates spent 11 years in Amazonia amassing large collections of insects that were sent back to museums and collectors in Europe. Bates was quick to embrace Darwin's and Wallace's theory of evolution by natural selection. Bates' own theory of mimicry, which now bears his name (Batesian mimicry), provided evidence for evolution by natural selection. |

Irish chemist who is remembered for his book, The Industrial Resources of Ireland (1944), a study of the scientific and potential economic value of developing the country's natural resources. Kane's began scientific research in his youth at his father's industrial chemicals factory. His first papers were published as a teenager. By the age of 22, he had already written a book, Elements of Practical Pharmacy, and was a professor of chemistry at Dublin's Apothecaries' Hall. In 1833, age 24, he published a paper in which he was the first to propose the existence of the -C2H5 ethyl radical (Dublin Journal of Medical and Chemical Sciences, which he founded). His research spanned inorganic, organic, physical, biological and applied chemistry.« |
| Lionel Lukin | |

English coach-builder, inventor and pioneer who patented the "unimmergible" (unsinkable) construction of the modern lifeboat (2 Nov 1785, GB No. 1498/1785*). His design used airtight compartments, cork, and other lightweight materials to build small boats that would not sink even when filled with water. Despite the patronage of the Price of Wales, he was unable to attract support for his invention from the Admiralty. Lukin fitted a coble for the the Rev. Dr. Shairp, of Bamborough, who was in charge of a charity for saving life and property at sea, which was reported to have saved several lives within its first year of use. Lukin's other inventions included a raft for rescuing persons under ice, an adjustable reclining hospital bed, and a rain gauge.« |
| Richard Mead | |
(source) |
British physician who contributed to preventive medicine and helped establish smallpox inoculation. He wrote works on plague, smallpox, measles and scurvy. His Mechanical Account of Poisons (1702) included observations from his tests of the effects of viper venom on the body. This treatise established his reputation, and he later enlarged and republished the book in 1743. To allay fears of a possible outbreak of plague, he published A Short Discourse Concerning Pestilential Contagion and the Methods to be Used to Prevent It (1720). He became wealthy as the pre-eminent medical practitioner of his day in London, and was physician to Royalty, statesmen and Sir Isaac Newton. Meade built an impressive collection of books, manuscripts, art and natural objects, but it was dispersed after he died.« |
