Person: Fenyő, István

István Fenyő was a Hungarian applied mathematician who worked in analysis, algebra, geometry and integral equations.

They provided an environment in which István, from a young age, was able to enjoy a wide variety of art forms as well as interesting himself in the humanities and sciences.
In 1939 Fenyő graduated with a qualification which allowed him to teach mathematics and physics at secondary school in Hungary.
Fenyő wrote a number of famous textbooks on applications of mathematics to chemistry and technology.
Fenyő's Hungarian text Mathematics in electrical engineering was written with Thomas Frey and published in two volumes, the first in 1964 with the second appearing in the following year.
Fenyő also wrote Moderne mathematische Methoden in der Technik Ⓣ(Modern mathematical methods in technology), a three volume work published in 1967, 1971 and 1980.
The first volume was written jointly with Thomas Frey, but the second volume was written by Fenyő alone.
The third volume published in 1980, although still presenting methods for engineers, is more involved with one of Fenyő's main research topics, namely integral equations.
Other books by Fenyő on integral equations are Integral equations - a book of problems (Hungarian) (1957), and the four volume work (written with H-W Stolle) Theorie und Praxis der linearen Integralgleichungen Ⓣ(Theory and practice of linear integral equations) (1982, 1983, 1983, 1984).
The soundness of his basic culture, coupled with his innate curiosity, led István Fenyő to seek the solution of problems in various areas of mathematics.

Born 5 March 1917, Budapest, Hungary. Died 28 July 1987, Budapest, Hungary.
