Bertrand, Joseph |
b.1822 d.1900 |
| French mathematician and educator remembered for his elegant applications of differential equations to analytical mechanics, particularly in thermodynamics, and for his work on statistical probability and the theory of curves and surfaces. |
 |
Danjon, André-Louis |
b.1890 d.1967 |
| French astronomer noted for his important developments in astronomical instruments and for his studies of the Earth's rotation. |
 |
Darboux, Jean Gaston |
b.1842 d.1917 |
| French mathematician who made important contributions to geometry and analysis and after whom the Darboux integral is named. |
 |
de Haas, Wander Johannes |
b.1878 d.1960 |
| Dutch physicist best known for the de Haas-van Alphen and Shubnikov-de Haas effects, descibing the quantum oscillations induced by a magnetic field, and the Einstein-de Haas effect, describing the rotation of a ferromagnetic material suspended in a magnetic field. |
 |
Dumas, Jean Baptiste André |
b.1800 d.1884 |
| French chemist who pioneered in organic chemistry, particularly organic analysis. |
 |
Fabry, Charles |
b.1867 d.1945 |
| French physicist specializing in optics, whose invention (with Perot) of the Fabry-Perot interferometer led him to discover the ozone layer in the upper atmosphere. |
 |
Ferraris, Galileo |
b.1847 d.1897 |
| Italian physicist who established the principles of the induction motor, which is now the principal device for the conversion of electrical power to mechanical power. |
 |
Fredholm, Erik Ivar |
b.1866 d.1927 |
| Swedish mathematician who founded modern integral equation theory. |
 |
Gill, Sir David |
b.1843 d.1914 |
| Scottish astronomer known for his measurements of solar and stellar parallax, showing the distances of the Sun and other stars from Earth, and for his early use of photography in mapping the heavens. |
 |
Kennelly, Arthur Edwin |
b.1861 d.1939 |
| American electrical engineer who made innovations in analytic methods in electronics, particularly the definitive application of complex-number theory to alternating-current circuits. |
 |
Mendeleev, Dmitri Ivanovich |
b.1834 d.1907 |
| (also spelt Mendeleyev). Russian chemist who developed the periodic classification of the elements. In his final version of the periodic table (1871) he left gaps, foretelling that they would be filled by elements not then known and predicting the properties of three of those elements. |
 |
Vaïsälä, Yrjö |
b.1891 d.1971 |
| Finnish meteorologist and astronomer noted for developing meteorological measuring methods and instruments. |
 |
Volterra, Vito |
b.1860 d.1940 |
| Italian mathematician who strongly influenced the modern development of calculus. |
