Born in Milan, Merz started drawing during World War II, when he was imprisoned for his activities with the Giustizia e Libertà antifascist group. He experimented with a continuous graphic stroke–not removing his pencil point from the paper. He explored the relationship between nature and the subject, until he had his first exhibitions in the intellectually incendiary context of Turin in the 1950s, a cultural climate fed by such writers as Pavese, Vittorini, and Ezra Pound.
