Alexei Arkhipovich Leonov[a] (30 May 1934 – 11 October 2019) was a Soviet and Russian cosmonaut and aviator, Air Force major general, writer, and artist. On 18 March 1965, he became the first person to conduct a spacewalk, exiting the capsule during the Voskhod 2 mission for 12 minutes and 9 seconds. He was also selected to be the first Soviet person to land on the Moon although the project was cancelled.

Leonov was an accomplished artist whose published books include albums of his artistic works and works he did in collaboration with his friend Andrei Sokolov. Leonov took coloured pencils and paper into space, where he sketched the Earth, becoming the first artist in space, and drew portraits of the Apollo astronauts who flew with him during the 1975 Apollo–Soyuz Test Project.[
