William G. Tifft was an astronomer at the University of Arizona. His main interests were in galaxies, superclusters and redshift quantization.[1] He was influential in the development of the first redshift surveys, and was an early proponent of crewed space astronomy, conducted at a proposed Moon base for example. In retirement, he was a principal scientist with The Scientific Association for the Study of Time in Physics and Cosmology (SASTPC).[2]
He had an A.B. in Astronomy from Harvard University (1954), and Ph.D. in Astronomy from the California Institute of Technology (1958) where he wrote his dissertation on photoelectric photometry.[3]
