László Egyed
László Egyed (12 February 1914 – 11 July 1970), was a well known geophysicist from Hungary who published over 100 scientific articles. In 1956, he wrote the book Physics of the solid earth, which was reworked and republished in 1969.[1][2]
Like Ott Christoph Hilgenberg, Samuel Warren Carey and Pascual Jordan, Egyed was a supporter of the Expanding Earth theory, an alternative to plate tectonics. Egyed calculated an annual enlargement of the earth radius by approximately 1 mm (500 km since the cambrian). On phenomenological basis, he proposed geophysical implications like a possible decrease of the gravitational constant in connection with phase transitions within the earth. Egyed's hypotheses of phase transitions were confirmed, however, modern theories don't see the cause of this phenomenon in an expanding earth.
After Egyed's death, in the commemoration of his worldwide recognized researches, the László-Egyed-Medal is awarded every 2 or 3 years for important contributions in the field of geophysics.
