Born Charles Holt in Los Angeles in February 1919 (some sources indicate 1918), western star Tim Holt was the son of silent screen actor Jack Holt. Spending a lot of time on movie sets as a child, it was natural for Tim Holt to become a movie star. However, following his parents' separation in the early 1930s, Holt was sent to a military boarding school. Upon graduation, Holt returned to Hollywood and had little trouble entering films. He had been in one of his father's films, The Vanishing Pioneer (1928), as a child. But at the age of 18, he was cast in a plum role in the popular drama Stella Dallas (1937; with Barbara Stanwyck and Anne Shirley).

In Antarctica, Holt is using airborne gravity and magnetics in conjunction with subglacial topography from radar sounding to delineate crustal boundaries and characterize active tectonics in the Amundsen Sea Embayment of West Antarctica. The glaciers of this basin appear to be losing more mass as a result of climate change than any others in Antarctica. The basin is ... characterized by the highest estimated geothermal flux in Antarctica, so the ice dynamical response to the geological boundary conditions of this region may dictate West Antarctica's contribution to global sea level change.
