MÉRAY-HORVÁTH, Károly (1859—1938). Engineer.

In 1885 he invented the casting machine for typesetting single letters. Before the first World-War the „Electrotypograph” manufactured in Germany and France was believed to represent the casting machine of the future. Unfortunately the first World-War stopped its spreading in the world.

MIHÁLY, Dénes (1894—1953). Mechanical engineer.

Mihály began his historical photoelectric and sound recording investigations as early as 1912. In August 1928 he introduced the first television at the official exhibition arranged by the German Post Office in Berlin. In November of the same year Mihály transmitted motion pictures. The historical culmination of Mihály’s accomplishments came at 11 p. m. on 31. Januar 1929 when the Berlin-Witzleben radio station broadcast the first moving television program in history.

NEUMANN, János (1903—1957). Mathematician.

(John von Neumann)

Neumann, one of the greatest mathematicians of our time, started his work in mathematical logics and set theory, and he is now thought of as the man who gave precision to this theory. In quantum theory, the mathematical foundation of the measurement theory of physical quantities was his greatest achievement („pure quantum mechanical conditions”). Neumann was also largely responsible for advances made in the theory of games and for the development of operational research. Neumann’s efforts were a critical contribution to the development of electronic computers (the use of the binary system, programme storage, instruction scheme, automatic programme modification).
