Considered one of the most important late-period Surrealist painters, Hérold was born in a Jewish family in Piatra Neamț, Romania.
He spent most of his childhood in the Danubian port city of Galați, where his father was making and selling candy.
He settled in Paris, where he maintained a close friendship with Constantin Brâncuși, for whom he also worked as a chef or even secretary.
Starting with this year's "Exposition Internationale du Surréalisme", he had an active presence in all the important Surrealist exhibitions worldwide.
During his lifetime, Hérold has done cover artwork and illustrations for more than 80 books by the likes of Gherasim Luca, Tristan Tzara, Francis Ponge, Julien Gracq, Marquis de Sade, Michel Butor, Alain Bosquet, Gellu Naum, Ilarie Voronca, Claude Sernet, etc.
