William G. Tifft is Emeritus Professor/Astronomer at the University of Arizona. His main interests are in galaxies, superclusters and what Tifft calls redshift problems (see redshift quantization). He was influential in the development of the first redshift surveys [1] and was an early proponent of manned space astronomy, conducted at a proposed moon base for example. In retirement, he is a principal scientist with the The Scientific Association for the Study of Time in Physics and Cosmology (SASTPC).[2]
