Humberto Marçal, born in Setúbal, is one of the leading figures in contemporary graphic work in Portugal. Since 1994, he has been responsible for the print and lithography editions at the Centro Português de Serigrafia, where he has generously engaged in dialogue and shared his wisdom with the new generations of artists. As a scholar of the Calouste Gulbenkian Foundation, Marçal attended the Royal Academy of Fine Arts in Liége, Belgium. He worked at Georges and Bransen's studio (lithography) and at the Polígrafa studio in Barcelona, specializing in artistic engraving. He has served as a technical advisor for courses and other training activities in engraving, lithography, and serigraphy at the most representative venues throughout the country. For several years, he was responsible for the edition of artistic engraving and lithography at the Sociedade Cooperativa de Gravadores Portugueses in Lisbon. In the field of restoration, Marçal has worked since 1970 at the Graphic Document Restoration Workshop of the Calouste Gulbenkian Museum. As an artist-engraver, Marçal has participated in important individual and collective exhibitions. In 2014, a retrospective exhibition of his work was held in Setúbal, the city of his birth, where he was rightfully awarded the Medal of Honor by the city.
