Who assembled the phonograph records that were included aboard both Voyager spacecraft launched in 1977?
Carl Sagan Carl Edward Sagan ( ; November 9, 1934 – December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the now accepted hypothesis that the high surface temperatures of Venus can be attributed to and calculated using the greenhouse effect.
Alan Lomax Alan Lomax ( ; January 31, 1915 – July 19, 2002) was an American ethnomusicologist, best known for his numerous field recordings of folk music of the 20th century. He was also a musician himself, as well as a folklorist, archivist, writer, scholar, political activist, oral historian, and film-maker. Lomax produced recordings, concerts, and radio shows in the US and in England, which played an important role in preserving folk music traditions in both countries, and helped start both the American and British folk revivals of the 1940s, 1950s and early 1960s. He collected material first with his father, folklorist and collector John A. Lomax, and later alone and with others, Lomax recorded thousands of songs and interviews for the Archive of American Folk Song, of which he was the director, at the Library of Congress on aluminum and acetate discs.
