Henry J. Glintenkamp
Henry J. Glintenkamp, the son of Hendrik and Sophie Dietz Glintenkamp, was born in Augusta, New Jersey, 1887. Glintenkamp received his elementary art training at the National Academy of Design (1903-1906) under Robert Henri and for a time shared the studio of Stuart Davis. He exhibited at the Armory Show in 1913.
He was a cartoonist who regularly contributed to the radical journal, The Masses. Glintenkamp believed that the First World War had been caused by the imperialist competitive system. After the USA declared war on the Central Powers in 1917, the journal came under government pressure to change its policy. When it refused to do this, the journal lost its mailing privileges. In July, 1917, it was claimed by the authorities that articles by Floyd Dell and Max Eastman and cartoons by Glintenkamp, Art Young and Boardman Robinson had violated the Espionage Act. Under this act it was an offence to publish material that undermined the war effort.
