He had initially hoped to become a Professor of theoretical physics but was eventually invited by Klein to found the world's first Institute of Geophysics, becoming the world's first Professor of Geophysics in 1898. He would remain there for the rest of his career, mentoring many students who became world-leading geophysicists and seismologists, including

275:. Wiechert was also interested in fields outside of fundamental physics and in 1896, he published the first verifiable model of the Earth's interior as a series of shells. Here he concluded that the difference between the density of the Earth's surface rocks and the mean density of the Earth meant that the Earth must have a heavy iron core. These were the foundations that one of Wiechert's students,

and created the field of geological prospecting using small, artificially-created earthquakes. Wiechert was also interested in theoretical physics, such as the theory by Albert
Einstein. He discussed the role of the ether and related questions with Hendrik Antoon Lorentz and others.
