| Gerd Faltings | |
(source) |
Gerd Faltings is a German mathematician who was awarded the Fields Medal, the highest honour that a young mathematician can receive, in 1986, primarily for his proof of the Mordell Conjecture which he achieved using methods of arithmetic algebraic geometry. He has also been closely linked with the work leading to the final proof of Fermat's Last Theorem by Andrew Wiles. In 1983 Faltings proved that for every n > 2 there are at most a finite number of coprime integers x, y, z with xn + yn = zn. This was a major step but a proof that the finite number was 0 in all cases did not seem likely to follow by extending Falting's arguments. However, Faltings was the natural person that Wiles turned to when he wanted an opinion on the correctness of his repair of his proof of Fermat's Last Theorem in 1994. |
| Baruch S. Blumberg | |
American research physician whose discovery of an antigen that provokes antibody response against hepatitis B led to the development by other researchers of a successful vaccine against the disease. He shared the Nobel Prize in Physiology or Medicine in 1976 with D. Carleton Gajdusek for their work on the origins and spread of infectious viral... |

| Jacques Piccard | |
Jacques (-Ernest-Jean) Piccard is a Swiss oceanic engineer, economist, and physicist, who helped his father, Auguste Piccard, build the bathyscaphe for deep-sea exploration and who also invented the mesoscaphe, an undersea vessel for exploring middle depths. Made deepest ocean dive ever at 35,800 feet in 1960. |

| Charles Townes | |
Charles Hard Townes is an American physicist, joint winner with the Soviet physicists Aleksandr M. Prokhorov and Nikolay G. Basov of the Nobel Prize for Physics in 1964 for his role in the invention of the maser and the laser. eb |

| Sir Grahame Douglas Clark | |
Sir (John) Grahame Douglas Clark was a British archaeologist and authority on the prehistoric age in northwestern Europe known as the Mesolithic Period (8000-2700 BC) |

| Earl S. Tupper | |

American manufacturer Earl Tupper, inventor of Tupperware, was born in New Hampshire. In the 1930's, Tupper invented a flexible, lightweight material that was used to make plastic gas masks during World War II. He then turned his attention to consumer products and created Tupperware - a line of plastic, airtight food storage containers. Sales languished in stores until it was discovered that home demonstrations better proved the value of the product, and thus, the Tupperware Party was born. It has since become a global institution in more than 100 countries. |
| Charles Dillon Perrine | |
U.S. astronomer who discovered the sixth and seventh moons of Jupiter in 1904 and 1905, respectively. In 1904 he published a calculation of the solar parallax (a measure of the Earth-Sun distance) based on observations of the minor planet Eros during one of its close approaches to the Earth. |

| Francis Crick | |

Francis Harry Compton Crick was a British biophysicist, who, with James Watson and Maurice Wilkins, received the 1962 Nobel Prize for Physiology or Medicine for their determination of the molecular structure of deoxyribonucleic acid (DNA), the chemical substance ultimately responsible for hereditary control of life functions. Crick and Watson began their collaboration in 1951, and published their paper on the double helix structure on 2 Apr 1953 in Nature. This accomplishment became a cornerstone of genetics and was widely regarded as one of the most important discoveries of 20th-century biology. |
| Abraham Pais | |

Dutch-American physicist and science historian whose research became the building blocks of the theory of elemental particles. He wrote Subtle Is the Lord: The Science and Life of Albert Einstein, which is considered the definitive Einstein biography. In Holland, his Ph.D. in physics was awarded on 9 Jul 1941, five days before a Nazi deadline banning Jews from receiving degrees. Later, during WW II, while in hiding to evade the Gestapo, he worked out ideas in quantum electrodynamics that he later shared when working with Niels Bohr (Jan - Aug 1946). In Sep 1946, he went to the U.S. to work with Robert Oppenheimer at Princeton, where Pais contributed to the foundations of the modern theory of particle physics. |
| Roger Tory Peterson | |
American ornithologist, author, conservationist, and wildlife artist whose field books on birds, beginning with A Field Guide to the Birds (1934; 4th ed. 1980), did much in the United States and Europe to stimulate public interest in bird study. |

| Colin Macmillan Turnbull | |
(source) |
English-born naturalized (1959) American anthropologist who gained fame with his book The Forest People (1962), a detailed study of the Mbuti Pygmies, a tribe in Zaire with whom he lived in affectionate intimacy for several years. In 1972, he wrote his most controversial book, The Mountain People, describing the Ik, an obscure nomadic tribe of hunters on the Kenya-Uganda border. They were living on the brink of starvation and cultural extinction, surviving (in diminishing numbers). Within one generation they had changed to a gross ethic of selfishness, having discarded love and morality. After the death of his African-American partner of 30 years, Turnbull retreated to a Buddhist monastery where he lived out his remaining years. |
| Otto Hahn | |

German chemist who, with the radiochemist Fritz Strassmann, is credited with the discovery of nuclear fission. He was awarded the Nobel Prize for Chemistry in 1944 and shared the Enrico Fermi Award in 1966 with Strassmann and Lise Meitner. Element 105 carries the name hahnium in recognition of his work. |
| Sir Flinders Petrie | |
![]() |
Sir William Matthew Flinders Petrie was a British archaeologist and Egyptologist who made valuable contributions to the techniques and methods of field excavation and invented a sequence dating method that enabled reconstruction of history from the remains of ancient cultures. He studied ancient British remains at Stonehenge (1875-80), then investigated pyramids at Giza and other Egyptian antiquities (1880-1914). He developed a principle of sequence dating by potsherds (1890). In 1895, he discovered remains of a prehistoric race at Nagada (1895). The stele of Merneptah he uncovered at Thebes in 1896 contained the earliest known Egyptian reference to Israel. He wrote The Formation of the Alphabet (1912). |

| Joseph Lee | |

Inventor and "Father of the American playground movement," who introduced the first contemporary neighborhood playground in the U.S. Born to a wealthy Boston family, Lee believed that with fortune comes responsibility. To counter social problems of the time, he promoted recreation activities as nurturing experiences. A Boston charity, copying a German practice, established sand-pile play areas among the Boston tenements. In the early 1890’s, Lee extended this idea by establishing his own playground for research and demonstration purposes. In speeches and articles Lee supported the spread of the playground movement across the U.S. |
| Jan Evangelista Purkinje | |
(source) |
Czech pioneer of experimental physiology whose investigations in the fields of histology, embryology and pharmacology helped to create a modern understanding of the eye and vision, brain and heart function, mammalian reproduction and the composition of cells. In 1837, Purkinje described not only clusters of beautiful drop-like cells, but also subtle elongated fiber-like processes in their vicinity, which seemed to be peculiar to the nervous system. Purkinje was the first to use the microtome, potassium bichromate and Canada balsam in the preparation of histological slides for microscopy. Purkinje introduced the scientific terms plasma, a component of blood, and protoplasm, used to describe young animal embryos. |
| Gaspard Monge | |

French mathematician who was one of the founders of descriptive geometry (the mathematics of projecting solid figures onto a plane, upon which modern engineering drawing is based) and the application of the techniques of analysis to the theory of curvature. The latter ultimately led to the revolutionary work of Georg Riemann on geometry and curvature. He became a close friend of Napoleon and was appointed minister for the navy (1792-93), but was stripped of all honours on the restoration of the Bourbons. He died in poverty. |
