Thomas Elek, also known as Tamás Elek and KERPAL (7 December 1924 – 21 February 1944) was one of 22 members of the French resistance convicted and executed at the fort of Mont Valérien as one of the Manouchian Group, part of the French liberation army FTP-MOI. After the executions, the Vichy government sought to discredit the resistance members, and widely distributed and posted thousands of copies of the Affiche Rouge. Named for its red background, the poster featured ten of the Manouchian group, including Elek. It identified him as "Elek Juif Hongrois 8 déraillements" (Elek, Hungarian Jew, 8 derailments).
