Enric Marco Batlle was a Spanish unionist who served as Secretary General of the Confederación Nacional del Trabajo (CNT) and as President of the Amical de Mauthausen in Spain. During his tenure, Marco gave numerous talks, primarily in schools, recounting his alleged experience as a survivor of Nazi concentration camps.

However, it was later revealed that he had fabricated parts of his biography, falsely claiming to have been a survivor of the Flossenbürg concentration camp during World War II.
