Evangelos Odysseas Papathanassiou ; 29 March 1943 – 17 May 2022), known professionally as Vangelis(/væŋˈɡɛlɪs/ vang-GHEL-iss; Greek: Βαγγέλης, pronounced [vaɲˈɟelis]), was a Greek composer and arranger of electronic, progressive, ambient, and classical orchestral music. He was best known for his Academy Award-winning score to Chariots of Fire (1981), as well as for composing scores to the films Blade Runner (1982), Missing (1982), Antarctica (1983), The Bounty (1984), 1492: Conquest of Paradise (1992), and Alexander(2004), and for the use of his music in the 1980 PBS documentary series Cosmos: A Personal Voyage by Carl Sagan.

Born in Agria and raised in Athens, Vangelis began his career in the 1960s as a member of the rock bands The Forminx and Aphrodite’s Child; the latter’s album 666 (1972) is now recognised as a progressive–psychedelic rock classic. Vangelis first settled in Paris, and gained initial recognition for his scores to the Frédéric Rossif animal documentaries L’Apocalypse des Animaux, La Fête sauvage, and Opéra sauvage.
