He was a pupil of state high school in Rypin, Poland, and he graduated from The First High School in Torun in 1950.
He studied mathematics in Nicolaus Copernicus University in Torun and Wroclaw University.
He defended his master thesis on some problems of the game theory prepared under supervision of Hugo Steinhaus at Wroclaw University in 1955.
In 1955 he became a faculty member at Department of Mathematics, Wroclaw University of Technology.
In 1959 he was distinguished as the candidate of science and in 1960 he defended his PhD on minimax estimation under supervision of Hugo Steinhaus.
Many years Trybula cooperated or was the staff member of Institute of Power Systems (IASE) in Wroclaw.
He worked out the original method of identification of the complex power systems.
Since 1968 he was faculty member of the Institute of Mathematics, Wroclaw University of Technology.
Stanislaw Trybula got habilitation at Faculty of Mathematics, Physics and Chemistry, Wroclaw University in 1968 based on his seminal works on sequential analysis for stochastic processes.
He took early retirement in 1998 and was writing academic books on statistics and the game theory.
Stanislaw Trybula is the co-author of the WJ bidding system in the bridge, known also as Polish Club (see also Trybula transfers, Wesolowski texas, Gawrys fourth suit forcing).
