Norwegian ethnologist and adventurer who organized and led the famous Kon-Tiki (28 Apr 1947) and Ra (1969-70) transoceanic scientific expeditions. Both expeditions were intended to prove the possibility of ancient transoceanic contacts between distant civilizations and cultures. The Kon Tiki voyage from Peru to Polynesia was a 101-day, 4,300-mile drifting voyage on the 40-sq.ft. raft, a replica of pre-Inca vessels. He wished to show that Polynesia's first settlers could have come from South America. Few scholars at the time, and almost none today, endorsed the idea. They discount the Heyerdahl hypothesis largely on linguistic, genetic and cultural grounds, all of which point to the settlers having come from the west, not the east.

Ernest Thomas Sinton Walton was an Irish physicist who was corecipient, with Sir John Douglas Cockcroft of England, of the 1951 Nobel Prize for Physics for the development of the first nuclear particle accelerator, known as the Cockcroft-Walton generator. The accelerator was built in a disused room in the Cavendish Laboratory, and supplied with several hundred kilovolts from a voltage multiplier circuit designed and built by Cockroft and Walton. On 14 Apr 1932 Walton turned the proton beam on to a lithium target. Despite all the odds against them, they succeeded in being the first to split the atom, and Walton was the first to see the reaction taking place. They identified the disintegration products as alpha particles (helium nuclei).

American scientist who developed the protein substance used for the tuberculosis skin test, and contributed to safety measures for intravenous drug therapy. In the early 1920s, she discovered that the sudden fevers that sometimes occurred during intravenous injections were caused by bacteria in the distilled water used to make the protein solutions. She invented a distillation apparatus designed to prevent such contamination. In 1941, her improved TB skin test became the standard test in the U.S. and a year later was adopted by the World Health Organization. It is still in use today. Her later research involved the study of bacteria associated with certain cancers.

Reginald Aubrey Fessenden was a Canadian-American physicist, engineer and inventor with 300 patents. He broadcast the first program of voice and music. In 1893, Fessenden moved to Pittsburgh as the head of electrical engineering at the university, Fessenden read of Marconi's work and began experimenting himself. Marconi could only transmit Morse code. But Fessenden's goal was to transmit the human voice and music. He invented the “continuous wave” AM radio: sound superimposed by amplitude modulation onto a carrier radio wave for transmission. A radio receiver extracts the signal from the carrier wave so the listener hears the original sound. Fessenden made the first long-range transmissions of voice on Christmas Eve 1906 from a station at Brant Rock, Massachusetts, heard hundreds of miles out in the Atlantic.

In 1856, he began university studies in natural science, but his interest turned to medicine and anatomy. After completing his doctoral dissertation (published 1862), he began teaching physiology, and thereafter published several papers on pathology. One of these, on the histological changes in muscles following typhoid fever, led at age 29 to appointment as a professor of pathology.

British pioneer in the design of precision tools. At 23, Ramsden chose to apprentice to a maker of mathematical instruments. By age 27 he had his own business in London and was known as the most skilful designer of mathematical, astronomical, surveying and navigationalinstruments in the 18th Century. He is best known for the design of a telescope and microscope eyepiece (ocular) still commonly used today and bearing his name. The French scientist N. Cassegrain proposed a design of a reflecting telescope in 1672. It was Ramsden, however, 100 years later, who found that this design reduces blurring of the image caused by the sphericity of the lenses or mirrors. He also built lathes, barometers, manometers and assay balances.

This in turn gives the distance from the Earth to the Sun, and the scale of the solar system. During the voyage he also experimented with the lunar position method of determining longitude. In 1764 he went on a voyage to Barbados to carry out trials of Harrison's timepiece, followed by appointment as Astronomer Royal (1765). In 1774, he carried out an experiment on a Scottish mountain with the use of a plumb line to determine the Earth's density. He found it was approximately 4.5 times that of water.

Simpson specialized in early fossil mammals, leading expeditions on four continents and discovering in 1953 the 50-million-year old fossil skulls of dawn horses in Colorado. He helped develop the modern biological theory of evolution, drawing on paleontology, genetics, ecology, and natural selection to show that evolution occurs as a result of natural selection operating in response to shifting environmental conditions. He spent most of his career as a paleontologist at the American Museum of Natural History.

Otto Fritz Meyerhof was a German biochemist and corecipient, with Archibald V. Hill, of the 1922 Nobel Prize for Physiology or Medicine for research on the chemical reactions of metabolism in muscle. In 1940 he emigrated to America. Meyerhof demonstrated that the production of lactic acid in muscle tissue, formed as a result of glycogen breakdown, was effected without the consumption of oxygen (i.e., anaerobically). The lactic acid was reconverted to glycogen through oxidation by molecular oxygen, during muscle rest. This line of research was continued by Gustav Embden and Carl and Gerty Cori who worked out in greater detail the steps by which glycogen is converted to lactic acid - the Embden-Meyerhof pathway.

He made important discoveries in the morphology and physiology of plants, especially in the fields of reproduction and evolution. Pringsheim's observation of the formation of plant cells provided support for the belief, opposed by the German botanist Matthias Jakob Schleiden, that cells arise only by division of pre-existing cells. In 1868 Pringsheim and Julius von Sachs were the first to describe the specialized bodies in the cell cytoplasm called plastids. Pringsheim also was the first to demonstrate a case of apospory, (production of a sexual generation from an asexual generation without the intervention of spores), in the Thallophyta (e.g., algae, fungi).

So he inoculated a rabbit with tuberculous material from a deceased human patient, tuberculous lesions were found in the rabbit three months later. Before Villemin, many scientists believed that TB was hereditary. In fact, some stubbornly held on to this belief even after Villemin published his results (1867), until the agent Mycobacterium tuberculosis was identified by Robert Koch (1882).

English physician who made a classic study of the medicinal use of digitalis. From his interest in botany, he paid attention to folk remedies used by herb-gatherers, including the foxglove. The leaf extract was efficacious in use for certain cases of "dropsy" (oedema, caused by heart failure). He determined the doses safe to use, and published a careful report of his findings in An Account of the Foxglove (1785). His report gave good case histories, including failures as well as successes. Thus he added digitalis as a very useful drug for physicians to use to steady and strengthen heart action. He was also a mineralogist, and witherite (barium carbonate) is named after him. He suffered greatly for years from chest disease, probably tuberculosis.

In 1997, American biology professor Stanley B. Prusiner won the Nobel Prize for medicine for discovering “prions,” described as “an entirely new genre of disease-causing agents.” The name means “proteinaceous infectious particle.” Prions cause brain diseases such as BSE (Bovine Spongiform Encephalopathy or “mad cow disease”); the human variant Creutzfeldt–Jakob disease; kuru among some peoples in New Guinea; and scrapie in sheep and goats. Prions are too small to be seen with normal microscopy. They are self-replicating, but contain no nucleic acid. Prions are highly resistant to destruction or denaturation by common chemical and physical agents such as disinfectants, formalin, heat, UV or ionizing radiation. Inceration of infected tissues requires a temperature never below 900ºF for four hours.«

His vaccine with live polio virus had proven safe in extensive tests on animals and humans. Worldwide tests of the new vaccine were slated to begin in the following year in the U.S. and four foreign countries. Sabin said arrangements had been made for a phamaceutical company to produce the vaccine, which he said would lost less than the cherry syrup it was in when administered by mouth.
