David Botstein is an American biologist who is the chief scientific officer of Calico. He was the director of the Lewis-Sigler Institute for Integrative Genomics at Princeton University from 2003 to 2013, where he remains an Anthony B. Evnin Professor of Genomics.

Maurice Sanford Fox was an American geneticist and molecular biologist, and professor of biology at the Massachusetts Institute of Technology (MIT), where he served as department chair between 1985 and 1989. His pioneering investigations of bacterial transformation helped illuminate the mechanisms by which donor DNA enters and is integrated into a host cell. His research also contributed to our understanding of mechanisms of DNA mutation, recombination, and mismatch repair more generally. Ancillary activities include his critical role in the establishment of the Council for a Livable World. He was married to photo researcher Sally Fox, who died in 2006, for over 50 years, and has three sons. Fox died in January 2020 at the age of 95.
