Kaulak

Antonio Cánovas del Castillo y Vallejo, better known as Kaulak (22 December 1862 – 13 September 1933), was a Spanish photographer, art critic, editor and amateur painter. His uncle was prime minister Antonio Cánovas del Castillo, assassinated in 1897 by an anarchist, hence his use of a pseudonym; the meaning of which is unexplained, although the word appears to be of Basque origin.
