Wald’s Contribution to Econometrics (= Ann. Mathem. Stat. 23/1952. pp. 21—27.1, The Publications of Abraham Wald (= Annals of Mathem. Stat. 23/1952. pp. 29— 33.), Wolfowitz J.: Remarks on the Theory of Testing Hypotheses (= New York Statistician 18/1967. no. 7. pp. 1—3.) DSB WINTER, Ernő (1898—1971). Chemical engineer. Winter is known for his many investions concerning electronic tubes, he elaborated an entirely new method for the production of oxide cathodes with the aid of barium metal vapor, developed multiple-grid final amplifier tubes, elaborated and patented a tube grid gilting process, a new process for the production of tungsten core metal oxide cathodes. He constructed improved stock cathodes which were simpler and less expensive than L-cathodes. Dr. Ernő Winter + (= Vacuum [London] 1972. pp. 25—26), VPMS Jan. 1957. p. 2. CH WINTNER, Aurél (1903—1958). Mathematician. In 1929 Wintner published „Spektraltheorie der unendlichen Matrizen”, which contains the first proofs of the basic facts in Hilbert space — the fundamental mathematical construct in the then-developing physical theory of quantum mechanics. Wintner’s work in America covered the entire range of classical analysis, from probability and analytic number theory to differential equations and basic questions in local differential geometry. He published several papers with Norbert Wiener in a branch of probability theory. He also produced works with several other mathematicians. WHC ZEMPLÉN, Géza (1883—1956). Chemist. Géza Zemplén founded the first school of organic chemistry in Hungary. He performed internationally acknowledged research in the field of carbohydrates and glycosides. Zemplén invented the „Zemplén saponification method” and a new technique for sugar decomposition bearing his name.

Ber. 92/1959. no. 2. pp. I—XIX ), Csűrös, Z.: In memóriám Géza Zemplén (= PPChem. 11/1967. pp. 9—15.) DSB, WHC, CH ZEMPLÉN, Jolán (1911—1974). Physicist, science-historian. In her early research work in physics she worked on the Zeeman effect of atmospheric oxygen streaks. Her first science-historical work was a general history of physics (1946) which can be used even today as a manual on this subject. This was followed by a remarkable book on Roger Bacon (1954). Her -two-volume monography about the history of Hungarian physics up to the end of the 18th century is a unique work. Her international activity as a science-historian is marked by several lectures abroad and by her research work on the general history of physics. St. Gazda: The science historian Jolán M.
