Károly Gerl

Károly Gerl (1857–1907), also known as Karl or Carl Gerl, was a Hungarian medallist and coin-die engraver. He was born in Neulerchenfeld (now part of Vienna) and died in Körmöcbánya (now Kremnica, Slovakia). He worked as an engraver at the Royal Hungarian Mint in Körmöcbánya during the late nineteenth and early twentieth centuries.

His documented works include memorial medals associated with György Szondi and Ágoston Trefort (1884). The Hungarian National Gallery holds the 1899 medal commemorating the breakthrough of the Nándor mining adit: its reverse bears the signature GERL K., while the obverse is signed by his fellow engraver József Reisner. Gerl also executed portrait medals, including a medal depicting Sándor Wekerle, and medals for the Hungarian Numismatic Society.

Signed medal dies and museum records establish his individual contribution to Hungarian medallic art. Works attributed to him are preserved in the Hungarian National Gallery and the Piarist Museum.
