TANULMÁNYOK - Vajda Pál: Creative Hungarians in mathematics, astronomy, physics, chemistry, technical sciences and industry. A selected bio-bibliography
theory of functions with complex variables, Fourier series, summability of divergent series, theory of interpolations. The notion of the transfinit diameter in the theory of complex functions and its application are to be considered as his most significant results. Rogozinski W. W.: M.

Albert Fonó carried out extensive research on converting heat energy into mechanical energy and worked out the first patent for the propulsion of an airplane by jet engines (1915). Avery W.

Nobel-laureate Dénes Gábor’s research activity encompassed a wide field. First he studied problems of electric currents in gases. He discovered many unknown relationships characterizing the so-called plasma in rarefied gases. In his most productive period, in the years following the lind World War, his interest turned to electronmicroscopy and in general to the mation of free electrons in space. The route from electron- and ion-physics lead him through electronmicroscopy to optics and the information theory, and in the meantime holography was created. The discovery of holography preceded its technical realization by twenty years. A really explosive development of holography commenced with the discovery of lasers, the sources of strong coherent radiation.

Mechanical engineer. In the Ford Motor Company the „Model T Ford” designed by József Galamb was introduced into production in 1908. This car was characterized by clever design, ingenious technological solutions and dependability. This car is credited with „putting America on wheels”. The Model T’s claim to greatness is based on the fact that it was the first satisfactory, reliable car produced for the mass market. It was designed to travel any road, through mud, snow and over rocks. Owners bragged that the Model T „would take you anywhere and bring you back”. Another remarkable construction of Galamb was the Fordson tractor (1918—20) that served as the model of the tractor manufacturing industry in the USA. His design of the planetary gears was eminent achievement of contemporary automobile technology. 57
