Isaac Díaz Pardo (22 August 1920 – 5 January 2012) was a Galician intellectual strongly attached to both Sargadelos [es] and Cerámica do Castro.

Díaz Pardo's father was executed by the Nationalists soon after the beginning of the Spanish Civil War and he was forced into hiding in La Coruña, where he stayed with his uncle Indalecio and found work as a signwriter.

After the war, he received a bursary from the Provincial Government of La Coruña that enabled him to study at the Royal Academy of Fine Arts of San Fernando in Madrid between 1939 and 1942.

He later taught at The Catalan Royal Academy of Fine Arts of Saint George in Barcelona, and began to exhibit in Spain (La Coruña, Madrid and Vigo) and abroad (Europe and The Americas).

At this point he experimented with the raw materials used in original 19th century works by Antonio Raimundo Ibáñez Llano y Valdés (notably from Sargadelos and Cervo).
