Charlie Duke’s personally owned and used slide rule, used from his college days through NASA. Aristo Multilog slide rule, made in Germany, is constructed of plastic, with a clear cursor, with four marks on one side and two on the reverse, and has 24 scales. This a more high end slide rule and is even equipped with small “feet” on one set of edges so it can be used while laying on a desk. Scale comes with its plastic conversion table and original box, and is signed on the box, “My slide rule used at MIT, USAF TPS, and NASA. Charlie Duke, Apollo 16.” Box also bears an older printed ballpoint signature, “C. M. Duke.” Duke graduated from MIT in 1964 with a degree in Aeronautics, took his primary flight training in 1958, and went on to graduate from the Aerospace Research Pilot School in 1965. He would join NASA as a Group 5 astronaut, and was Capcom during the Apollo 11 mission, speaking the first words to the lunar module after it touched down on the moon. One can imagine this important tool saw much use, perhaps even at his post during Apollo 11. Pre-certified Scott Cornish and RR Auction COA.
