Egon Zakrajšek (
July 7 ,1941 - September 2002) was a Slovenemathematician andcomputer scientist .Zakrajšek was born in
Ljubljana ,Yugoslavia (todaySlovenia ). He became an orphan even before he started to attend school. He went to elementary school and gymnasium inJesenice . He was a good student and he showed his talent and abilities very early. He graduated from technical mathematics at the Department of mathematics and physics of then Faculty for natural sciences and technology (FNT) of theUniversity of Ljubljana . He received hisMaster's degree at theUniversity of Zagreb with a work "Numerična realizacija Ritzovega procesa" ("Numerical realization of theRitz process ") and his doctorate in 1978 in Ljubljana with a dissertation "O invariantni vložitvi pri reševanju diferencialnih enačb" ("About the invariable embedding in solving ofdifferential equation s").Professor Zakrajšek was one of the pioneers of
computer science in Slovenia. He became an expert about the firstcomputer s of theUniversity of Ljubljana , the ZuseZ-23 and its successor theIBM 1130 . Later on he participated in the development ofprogramming language s, tools andoperating system s. He wrote textbooks and manuals for them simultaneously: for Z-23 assembler, Algol,Fortran ,Algol 68 , Pascal, for domestic structran. In 1982 he set off forUnited States and he became the manager of the programming equipment at the firmCromemco . In 1994 he returned to homeland, where he occupied professorship again. With his advocacies about the C and open operating systems, that is,Unix andLinux , he helped to modernize the lessons of computer science. He became an expert again forTeX ,LaTeX andMATLAB .Beside his computer science skills he was also an excellent mathematician with a broad profile. He taught and solved problems from many fields: the usage of mathematics in natural and social sciences,
statistics ,mechanics , classicalapplied mathematics ,discrete mathematics , graph andnetwork theory ,linear programming , operational researches,numerical analysis .References
