Andrija Mohorovicic was born in 1857 in Volosca and died in 1936. He studied in Prague and later taught for nine years at the Nautical School in Bakar. In 1892 was appointed director of the Meteorological Observatory in Zagreb. After a few years he taught at the University of Zagreb, and towards the end of the 19th century, he was a distinguished member of the Academy of Sciences in Zagreb. At the beginning of his scientific career he devoted much of his energy to meteorology, but had significantly more success in the field of seismology and founded the so-called “School of Zagreb,” which gained worldwide recognition in this field of science.

According to Mohorovicic’s theory, the seismic waves created by earthquakes at shallow depth, spread through the Earth’s interior. With his researches he discovered a discontinuity of speed that separates the crust from the mantle below. Later, scientists confirmed the correctness of Mohorovicic’s theory, and they recognized the existence of this discontinuity in all the continents and oceans. This theory was named, in honour of Mohorovicic, ” the Mohorovicic Discontinuity.”
