Andrija Mohorovičić (23 January, 1857 – 18 December, 1936) was a Croatian meteorologist and seismologist. He is best known for the eponymous Mohorovičić discontinuity and is considered a founder of modern seismology. By analyzing data from more observation posts, Mohorovičić concluded that the Earth has several layers above a core. He was the first to establish, based on the evidence from seismic waves, the discontinuity that separates the Earth’s crust from its mantle. This is now called the Mohorovičić discontinuity. In his honor in 1996 Asteroid No. 8422 was named – 8422 Mohorovicic.
