Lajos Takács
Lajos Takács (August 21, 1924 (
Hungarian mathematician, known for his contributions to probability theory and in particular, queueing theory
. He wrote over two hundred scientific papers and six books.
He studied at the
M.S. for his dissertation On a Probability-theoretical Investigation of Brownian Motion (1948). From 1945-48 he was a student assistant to Professor Zoltán Bay
and participated in his famous experiment of receiving microwave echoes from the Moon (1946). In 1957 he received the Academic Doctor's Degree in Mathematics for his thesis entitled "Stochastic processes arising in the theory of particle counters" (1957).
He worked as a mathematician at the
semi-Markov processes in queueing theory.[2]
He took a lecturing appointment at
Imperial College in London and London School of Economics (1958), before moving to Columbia University in New York City (1959–66) and Case Western Reserve University in Cleveland (1966–87), advising over twenty Ph.D.-theses.[3] He also held visiting appointments at Bell Labs and IBM Research, had sabbaticals at Stanford University
(1966). He was a Professor of Statistics and Probability at Case Western Reserve University from 1966 until he retired as Professor Emeritus in 1987.
Takács was married to
Notre Dame College of Ohio. He had two daughters, contemporary figurative realist artist, Judy Takács
and Susan, a legal assistant.
