Sadakichi Hartmann (1867-1944) was a photography critic and poet of German and Japanese descent. Hartmann, born on the artificial island of Dejima, Nagasaki to German businessman Carl Herman Oskar Hartmann and Japanese mother Osada Hartmann and raised in Germany, arrived in Philadelphia in 1882 and became an American citizen in 1894. An important early participant in modernism, Hartmann was a friend of such diverse figures as Walt Whitman, Stéphane Mallarmé and Ezra Pound. His poetry, deeply influenced by the Symbolists as well as orientalist literature, includes 1904's Drifting Flowers of the Sea and Other Poems, 1913's My Rubaiyat and 1915's Japanese Rhythms.
