Artist born in Mexico City, in 1939. He trained at the Academy of San Carlos, at Mexico City College (today University of the Americas) and drawing and painting workshops by teachers Arnold Belkin, Silva Santamaría, Antonio Rodríguez Luna and Muñoz Medina. He always considered drawing as an autonomous territory, with the same artistic dignity as painting, so he dedicated himself to this technique in an especially intense way over more than three decades. His work was full of passion, sensuality, humor, critical gaze and a repeated ironic perspective that tried to strip the objects and beings of that pompous solemnity behind which often hide other "realities" that Cohen insisted on discovering time to build Hence his inclination towards expressionist drawing as a way to choose to show reality, not as it appears to our senses but as perceived by an intensely subjective look that changes, disrupts and alters our customary conventions to express a deeply personal emotion.
