Stephanos Christopoulos, born in 1876, was a prominent Greek athlete known for his prowess in both weightlifting and amateur wrestling. He was a dedicated member of Gymnastiki Etaireia Patron, a club that later merged in 1923 with Panachaikos Gymnastikos syllogos to form Panachaiki Gymnastiki Enosi.
Christopoulos made his mark on the international stage at the inaugural modern Olympic Games held in Athens in 1896. He showcased his wrestling skills by defeating Hungary's Momcsilló Tapavicza in the first bout, demonstrating remarkable endurance and technique. However, his journey ended in the semifinals against fellow Greek competitor Georgios Tsitas, where an unfortunate shoulder injury led to his defeat. Despite this setback, Christopoulos secured a bronze medal, finishing behind Tsitas and German wrestler Carl Schuhmann.
A decade later, in 1906, Christopoulos returned to competition at the Intercalated Games in Athens. He participated in three events, starting with the two-handed weightlifting lift, where he impressively lifted one hundred eight point five kilogrammes, earning a tie for seventh place. In the one-handed lift, he managed to lift forty kilogrammes, finishing eleventh out of twelve competitors. Additionally, he competed in the heavyweight wrestling division, winning his first match against Austrian Rudolf Arnold but ultimately losing to Belgium's Marcel Dubois in the subsequent round.
