Harald Ulrik Sverdrup was a Norwegian meteorologist and oceanographer known for his studies of the physics, chemistry, and biology of the oceans. He explained the equatorial countercurrents and helped develop the method of predicting surf and breakers. As scientific director of Roald Amundsen's polar expedition on Maud (1918-1925), Sverdrup worked extensively on meteorology, magnetics, atmospheric electricity, physical oceanography, and tidal dynamics on the Siberian shelf, and even on the anthropology of Chukchi natives. In 1953, Sverdrup quantified the concept of "critical depth", explaining the onset of the spring phytoplankton bloom in newly stratified water columns. |
| Sir Frederick Handley Page | |

British aircraft designer who built the Handley Page 0/400, the world's first twin-engine bomber for the Royal Flying Corps, one of the largest planes used in WW I, which carried out their first large-scale bombing raids on enemy military installations and submarine bases in Nov 1916. By 1918, he had produced a four-engine bomber that could attack the industrial zones of the Saar and the Ruhr in Germany. In 1930, he produced the first 40-seat civilian airliner, the Hercules. For WW II, Page returned to producing military aircraft, the most important being the Halifax bomber. The government purchased 7,000 of these planes. He was knighted for his contribution to the war effort. After the war Page designed the four-engine jet bomber, the Victor. |

Schack August Steenberg Krogh was a Danish physiologist who received the Nobel Prize for Physiology or Medicine in 1920 for his discovery of the motor-regulating mechanism of capillaries (small blood vessels). Working with frogs, which he injected with Indian ink shortly before killing, he showed that in sample areas of resting muscle the number of visible (stained) capillaries was about 5 per square millimeter; in stimulated muscle, however, the number was increased to 190 per square millimeter. From this he concluded that there must be a physiological mechanism to control the action of the capillaries in response to the needs of the body (not just flow due to heart beating). Krogh's research linked exercise physiology with nutrition and metabolism. |

American physician who was a pioneer in public health and child welfare in the United States. She was appointed assistant to the Commissioner for Public Health of New York City, later heading the city's Department of Health in 'Hell's Kitchen' for 25 years. Convinced of the value of well-baby care and the prevention of disease, in 1908 she founded the Bureau of Child Hygiene after visiting mothers on the lower east side, thus helping to decrease the death rate by 1200 from the previous year. Her work made the New York City infant mortality rate the lowest in the USA or Europe at the time. She set up free milk clinics, licensed midwives, and taught the use of silver nitrate to prevent blindness in newborns. |
| Michel Chasles | |
![]() |
French mathematician who, independently of the Swiss-German mathematician Jakob Steiner, elaborated the theory of modern projective geometry, the study of the properties of a geometric line or plane figure that remain unchanged when the figure is projected onto a plane from a point not on either the plane or the figure. In his text Traité de géométrie in 1852 Chasles discusses cross ratio, pencils and involutions, all notions which he introduced. Chasles was the victim of a celebrated fraud paying the equivalent of 20,000 pounds for various letters from famous men of science and others which turned out to be forged. |
| Sir William (Frederick) Herschel | |
(source) |
German-born British astronomer, the founder of sidereal astronomy for the systematic observation of the heavens. In 1773, Herschel made and began using his first telescope. With it he began a project that would continue for the rest of his life: that of systematically studying the sky. Through this study he discovered the planet Uranus, many new nebulae, clusters of stars and binary stars. Herschel hypothesized that nebulae are composed of stars, developed a theory of stellar evolution and was the first person to correctly describe the form of our Galaxy, the Milky Way. He discovered the Saturnian satellites Mimas and Enceladus (1789) and the Uranian satellites Titania and Oberon (1787). He was probably the most famous astronomer of the 18th century. |

| Margaret Mead | |
(source) |
American anthropologist whose great fame owed as much to the force of her personality and her outspokenness as it did to the quality of her scientific work. As an anthropologist, she was best-known for her studies of the nonliterate peoples of Oceania, especially with regard to various aspects of comparative child psychology, oceanic ethnology, cooperation and competition among primitive peoples, and cross-cultural communications. She was twenty-three years old when she first traveled to the South Pacific, to conduct research for her doctoral dissertation. The resulting book, Coming of Age in Samoa, was - and remains - a best-seller. She continued her research throughout her life in such locations as New Guinea, Samoa, Bali, and many other places. |
| Elmer McCollum | |
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.« |

| Allen B. Du Mont | |
(source) |
Allen B(alcom) Du Mont was an American engineer who perfected the first commercially practical cathode-ray tube, which was not only vitally important for much scientific and technical equipment but was the essential component of the modern television receiver. The early cathode ray tubes were imported from Germany at high cost, but they burned out after 25 or 30 hours. In the 1930's, he simplified and improved the production of cathode ray tubes lasting a thousand hours. A financially successful by-product of his television work was the cathode ray oscillograph. After WW II, Du Mont had become the industry's first millionaire, investing also in broadcasting stations. The Du Mont Broadcasting Co. he began in 1955 grew to become Metromedia, Inc. |
| C.T.R. Wilson | |
(EB) |
Scottish physicist who, with Arthur H. Compton, received the Nobel Prize for Physics in 1927 for his invention of the Wilson cloud chamber, which became widely used in the study of radioactivity, X rays, cosmic rays, and other nuclear phenomena. His discovery was a method of rendering visible the tracks of such electrically charged particles. It is based upon the formation of clouds, which develop when sufficiently moist air is suddenly expanded, thus dropping the temperature below the dew-point. Thereafter, vapour condenses into small drops, formed round dust particles, or even, an electrically charged atomic particle. The formation of droplets is so dense that photographs show continuous tracks of particles travelling through the chamber as white lines. |
| Frank M. Chapman | |
(source) |
Frank M(ichler) Chapman was an American ornithologist famous for his extensive and detailed studies of the life histories, geographic distribution, and systematic relationships of North and South American birds. He joined the American Museum of Natural History in 1888, where he spent his life. By 1920, he was the first Chairman of the newly created Department of Birds. Chapman did pioneer work on Neotropical biogeography. Sensitive to the living environment of birds and other animals, he developed the “habitat group” as a means of display in the Museum, a feature now widely adopted by other museums through the world. A leading conservationist, Chapman was a prolific author who popularized bird study and raised awareness for conservation in the U.S. |
| Andre-Eugene Blondel | |
(source) |
André-Eugène Blondel was a French physicist who invented (1893) the electromagnetic oscillograph, a device that allowed electrical researchers to observe the intensity of alternating currents. In 1894, he proposed the lumen and other new photometric units for use in photometry, based on the metre and the Violle candle. Endorsed in 1896 by the International Electrical Congress, his system is still in use with only minor modifications. Blondel was a pioneer in the high voltage long distance transport of electric power, and also contributed to developments in wireless telegraphy, acoustics, and mechanics. He proposed theories for induction motors and coupling of a.c. generators.« |
| Thomas Chrowder Chamberlin | |

U.S. geologist and educator, born in Mattoon, Illinois, known for his "planetesimal hypothesis". With Forest Ray Moulton in 1904, he proposed that the solar system formed after gas flares were ripped from the sun by the gravitational field of a passing star. The flares then condensed into "planetesimals," arrayed in a spiral extending from the sun, gradually accumulated material and became the planets we know today. From 1876, he was Wisconsin Geological Survey's chief geologist, moving to head the glacier division of the U.S. Geological Survey (1881). He was president of the University of Wisconsin (1887-92), and then for 26 years he was head of its geology department of the University of Chicago. He founded The Journal of Geology. |
| Alfred Werner | |
(source) |
French-born Swiss chemist whose founding research into the structure of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner "coordination compounds."' and the maximum number of atoms (or "ligands" as he called them) that can be joined to the central metal is its coordination number. |

American inventor of the ring spinning machine (1828), which by the 1860s had largely replaced Samuel Crompton's spinning mule in the world's textile mills because of its greater productivity and simplicity. The ring frame is a continuous spinner, which spins yarn and winds it onto bobbins in one motion, while the mule was a discontinuous spinner, first spinning a length of yarn and then winding that length onto bobbins separately. In ring spinning, a "c"-ring travels at a high speed around a grooved circular raceway mounted on a plate, which in turn travels up and down the spinning bobbin. |
| William Murdock | |
(source) |
Scottish inventor, the first to make extensive use of coal gas for illumination and a pioneer in the development of steam power. He joined James Watt and Matthew Boulton and in 1784 he was sent to supervise the installation of Boulton & Watt steam engines working pumping equipment in Cornish tin mines. While there, he tested his ideas to use the gas given off by burning coal. From an iron retort in the backyard of his home, he ran a metal tube into his living room. On 29 Jul 1792, Murdock achieved a gas flame inside the room. In 1802, Boulton installed two gas lamps outside his Soho factory. Next year, the foundry was entirely illuminated by gas. Shortly, Boulton & Watt began to sell lighting and heating equipment with Murdock as a partner in the business. |
| Daniel Rutherford | |
(source) |
Scottish chemist who discovered the portion of air that does not support combustion, now known to be nitrogen. After letting a mouse live in a confined quantity of air until it died, he burned a candle and burned phosphorus in the same air as long as they would burn. He assumed the remaining gas was carbon dioxide, which he dissolved by passing it through a strong alkali. Yet there remained gas that was incapable of supporting respiration or combustion which he knew no longer contained oxygen or carbon dioxide. He called it "phlogisticated air," following the phlogiston theory of Stahl. It was later properly described by Lavoisier. Rutherford also designed the first maximum-minimum thermometer. |
| Jean-Marie Roland (de La Platière) | |
(source) |
French industrial scientist who, largely through his wife's ambition, became a leader of the moderate Girondin faction of bourgeois revolutionaries during the French Revolution. Roland became an inspector general of commerce in 1780, and over the next decade he wrote a number of books on manufacturing and political economy. |
| Franciscus Sylvius | |
(EB) |
Dutch physician, chemist and physiologist who was the founder of the seventeenth century's "iatrochemical school of medicine," which related living processes to chemical reactions. Thus, Sylvius helped move medicine away from mysticism (with its "humours" of blood, phlegm and biles) and towards an approach based in physics and chemistry. Sylvius strongly supported Harvey's view of blood circulation, and viewed the body chemistry as a balance between base and acids, capable of neutralizing each other. Sylvius and his followers studied the digestive juices, with which they recognized saliva, and viewed digestion as a kind of fermenting process. He may also have organized the first university chemistry laboratory. |
| Johannes Kepler | |
(source) |
German astronomer who formulated three major laws of planetary motion which enabled Isaac Newton to devise the law of gravitation. Working from the carefully measured positions of the planets recorded by Tycho Brahe, Kepler mathematically deduced three relationships from the data: (1) the planets move in elliptical orbits with the Sun at one focus; (2) the radius vector sweeps out equal areas in equal times; and (3) for two planets the squares oftheir periods are proportional to the cubes of their mean distances from the sun. Kepler suggested that the tides were caused by the attraction of the moon. He believed that the universe was governed by mathematical rules, but recognized the importance of experimental verification.« |
