Timoleon Argyropoulos (Greek: Τιμολέων Αργυρόπουλος April 12, 1847 - January 16, 1912) was an experimental physicist, mathematician, author, and professor.

Argyropoulos along with other world-renowned Greek scientists Anastassios Christomanos, Konstantinos M. Mitsopoulos, Spyridon Miliarakis, Nikolaos Apostolidis, and Anastasios Damvergis filed a memorandum to the Greek state to separate the schools in the late 1800s.

He heavily discussed electricity and modern pioneers such as Thomas Edison and Nikola Tesla.

[3][4][5][6][7][8] He was born in Athens, Greece to Athanassios Argyropoulos and Fanny Frangueska Amallia Kraus.

His parents were married at the German Evangelical Community Church in Athens on July 27, 1839.

His mother is buried at the Protestant cemetery of Athens but her statue is at the A' Nekrotafeion at her husband's tomb.

He studied at the Sorbonne from 1867 to 1871 and then he attended the prestigious French university Ecole des Mines from 1871 to 1874.

Argyropoulos and Anastassios Christomanos along with other members of the Greek scientific community lobbied to separate the physics and mathematics department from the philosophical school.

Argyropoulos and his contemporaries in Greece and abroad were part of the new scientific movement introducing new theories and concepts.

Scientist proposed the existence of a space-filling substance or field as the transmission medium for the propagation of electromagnetic or gravitational forces.

Argyropoulos and Greek physicist Vassilios Lakon believed that the absolute vacuum was not possible within the ether.

Power described the physical condition of a body combined with the repulsive forces caused by heat.

Argyropoulos and Lakon accepted the principle of Earth's rotation proposed by the foucault pendulum.

Lakon incorporated modern concepts of electromagnetism and discussed Oersted, the law of Biot-Savart, and the telegraph.
