Henri-Achille Zo (2 December 1873, Bayonne – 9 September 1933, Onesse-Laharie) was a French painter and illustrator of Basque ancestry.
[1] He began as a pupil of his father, the painter Achille Zo, who was Director of the École des beaux-arts de Bordeaux [fr].
Later, he studied with Léon Bonnat and Albert Maignan at the École nationale supérieure des beaux-arts in Paris.
[2] He and his father were considered to be the founders of the style that came to be known as the "Bayonne School",[3] which featured scenes from Spain and bullfighting tableaux.
He was awarded a silver medal at the Exposition Universelle (1900), which resulted in his receiving a government travel grant the following year.
