The Mohorovičić discontinuity, usually referred to as the Moho, is the boundary between the Earth's crust and the mantle. The Mohorovičić discontinuity was first identified in 1909 by Andrija Mohorovičić when he observed the abrupt increase in the velocity of earthquake waves at this point.

Andrija Mohorovicic was a prominent Croatian scientist in the field of meteorology and seismology at the end of the nineteenth and in the early twentieth century.
In these studies he was the first in the world to establish, on the basis of seismic waves, a surface of velocity discontinuity that separates the crust of the Earth from the mantle and which was named the MohorovicicDiscontinuity in his honour.
Mohorovicic's thoughts and ideas were truly visionary and came to expression many years later (the effects of earthquakes on buildings, harnessing the energy of the bura, models of the Earth, deep-focus earthquakes, hail defence, locating earthquake epicentres, seismographs, etc.).
