Dr. Dragan Hadžievski, born in 1928 in Galičnik, Doctor of Physical Sciences and Full Professor, was Head from March 1, 1961 to July 5, 1988. He graduated from the Faculty of Philosophy at the University in Skopje, Department of Physics, in 1957, and in 1958 he was appointed as an assistant at the Seismological Station of the University in Skopje. In 1961, he completed a specialization in seismology at the Geophysical Institute “Andrija Mohorovičić” at the Faculty of Science of the University in Zagreb. The same year, he was appointed Head of the Seismological Station at the University in Skopje. During 1966, he completed a six-month specialization in seismology at the Institute of Earth Physics of the Academy of Sciences of the USSR (Moscow). In 1967, he was elected to the position of Research Associate in Seismology at the Observatory. In 1978, he earned his PhD at the Geophysical Institute “Andrija Mohorovičić” at the Faculty of Science of the University of Zagreb, defending his doctoral dissertation entitled “Physical Characteristics of Earthquake Foci” (Fizikalne karakteristike žarišta potresa). At the Faculty of Physics in Skopje, he was elected Associate Professor in 1976, and in 1981 he was promoted to Full Professor. In 1987, he was re-elected to the position of Full Professor. He remained Head of the Observatory until July 1988, when he was retired under a special republican law on retirement. From 1969 to 1985, he delivered lectures in General Seismology and Engineering Seismology within the international postgraduate studies at the Institute of Earthquake Engineering and Engineering Seismology (IZIIS) in Skopje. He also taught General Seismology at the International Course on Aseismic Construction for candidates from developing countries (CADAC) at the same institute. From 1986 to 1990, he lectured on the Physics of the Earthquake Source in postgraduate studies at the Geophysical Institute “Andrija Mohorovičić” at the Faculty of Science of the University in Zagreb. He supervised domestic and international master and doctoral students in seismology. His scientific and professional activity covered all areas of seismology, as well as other fields of the physics of the Earth’s interior and geophysics as a whole. He is regarded as the founder of theoretical seismology and the seismological service in the Republic of Macedonia. He participated in five international scientific projects and led six national scientific projects. As an author or co-author, he published 64 scientific papers. Independently or in co-authorship, he also published 56 papers related to applied projects and prepared around 70 other professional works. He was a member of the International Association of Seismology (IAS) and the European Seismological Commission (ESC), a delegate to the Seismological Community of the SFRY, a member of the Society of Physicists of Macedonia, and a member of the Association of Seismologists of Macedonia. He served on the editorial board of the distinguished journal “Acta Seismologica Iugoslavica” from 1971 to 1991 (Editor-in-Chief from 1979 to 1986). He was also Editor-in-Chief of the journal “Occasional Publications of the Seismological Station in Skopje” (1965–1967), and one of the editors of the “Catalogue of Earthquakes of the Balkan Region for the Period 1901–1970.” For his scientific and professional work, he received the following awards:
