What nationality was Alexander Archipenko?

Alexander Archipenko was Ukrainian.

Archipenko was born in Kyiv in 1887, when the city was part of the Russian Empire and Ukraine was not yet an independent state. His birthplace is now the capital of Ukraine, and he is widely identified as a Ukrainian-American avant-garde artist and sculptor. He later worked in France and the United States, but those stages of his career do not change his national origin.

He studied at the Kyiv Art School before moving to Moscow and then Paris, where he joined the international avant-garde. In Paris, he became one of the earliest sculptors to apply Cubist ideas to three-dimensional art. His sculptures broke figures into geometric forms and made inventive use of concave spaces, openings and unconventional materials.

The main potential confusion is between nationality, political borders and later citizenship. Archipenko was born in the Russian Empire, emigrated to France in 1908, and eventually became an American citizen. For a question asking what nationality he was, “Ukrainian” is the standard answer.
