Konstantin Momirović was born in 1932 in Tetovo (Former Yugoslav Republic of Macedonia). He later moved to Montenegro and then to Belgrade. In 1950 he arrived in Zagreb where he studied psychology at the Faculty of Humanities and Arts. He won his PhD at the same faculty with the thesis Structure of Factors in some Neurotic Symptoms. In 1991 he returned to Belgrade where he lived and worked until his death in 2004.
Most of his working career was dedicated to computer processing and data analysis. As a very active athlete (he held a fourth degree black belt in judo, among other things) he also dealt with physical education.
His career in physical education started at the College of Physical education in 1960 and later at the Faculty for Kinesiology in Zagreb, where for a time he was also the dean.
Momirović worked at SRCE (University Computing Centre) since its establishment in 1971 and in 1979 became its general manager.
He taught subjects related to data analysys at several faculties and was a member and president of several Croatian boards and committees that dealt with education and information technology.
Some of his greatest contributions to science include the development of the cybernetic model of personality, the canonical analysis of covariance and the factorisation halting method (the PB criterion). He received a number of acknowledgements for his scientific contributions in the field of information technology, kinesiology, psychology and biological anthropology.
