TANULMÁNYOK - Vajda Pál: Creative Hungarians in mathematics, astronomy, physics, chemistry, technical sciences and industry. A selected bio-bibliography
# KLUPATHY, Jenő (1861—1931). Physicist. Klupathy conducted important research work in the fields of electricity and magnetism. He solved the technical problem of acoustic remote control, and carried on significant investigations on the strength of liquids. In. Hungary Klupathy made the first X-ray picture, repeating and verifying Prof. Roentgen’s experimental findings, and discovered that aluminium was X-ray permeable in spite of its metal character; he proved that if the discharges in the tube were transformed, the exposure time decreased, the life of the tube was considerably reduced. HMR KONKOLY-THEGE, Miklós (1842—1916). Astronomer. Konkoly-Thege was a pioneer of Hungarian astronomy. The most important instrument in his observatory was a 25,4 cm März-Konkoly refractor of his own design. He also designed a large telescope for solar observations, heliographs, a lunar camera etc. Konkoly-Thege was chiefly interested in the new methods of celestial photography and astrophysics — especially spectroscopy. Among his several inventions are the Konkoly-Thege diagrams which are still used today. He was the first to conduct astrophysical investigations and is now considered the founder of this young discipline. M.

He built the first electricity-driven automobile, was the first to produce fer- rosilicon in electrical ovens, dealt also with mathematical problems, elaborated a plan for rendering the river Danube navigable, and in 1892 invented the rotating condenser.

KÖNIG, Gyula (1849—1913). Mathematician König’s most important work is the voluminous „Einleitung in die allgemeine Theorie der algebraischen Grössen”, published in German and Hungarian in 1903. This book draws heavily on a fundamental study by Kronecker, „Grundzüge einer aritmetischen Theorie der algebraischen Grössen” (1892), although König had very little personal contact with Kronecker. In his work Kronecker had set forth the principles of the part of algebra later called the theory of polynominal ideals. König developed Kronecker’s results and presented many of forms, elimination theory, and Diophantine problems. In the last eight years of his life König took great interest in Cantor’s set theory and the discussion that it provoked concerning the foundations of mathematics. DSB, WHC KÖVESLIGETHY, Radó (1862—1934). Astronomer, seismologist. He was doing pioneering work in the research of spectral intensities of incandescent bodies, and published in 1899 for the first time theoretically obtained 49
