Charles Sheldon Hastings (November 27, 1848 – January 31, 1932) was an American physicist known for his work in optics.[1] He was an associate professor of physics at Johns Hopkins University and the first Chair of Professor of Physics of Sheffield Scientific School at Yale University.[2] He collaborated with John A. Brashear on the optical design of large telescopes including the 72-inch (180 cm) reflector at Dominion Astrophysical Observatory and the 30-inch (76 cm) photographic refractor at Allegheny Observatory.[3] His optical designs enabled much progress in astronomy at U.S. observatories.[4] The Hastings Triplet magnifying glass design is based on his optical formulae.[5] He was awarded the Elliott Cresson Medal in 1926.[6]

He was a member of the Connecticut Academy of Arts and Sciences.
