Louis French Reichardt is a noted American neuroscientist and mountaineer, the first American to summit both Everest and K2. He was also director of the Simons Foundation Autism Research Initiative, the largest non-federal supporter of scientific research into autism spectrum disorders and is an emeritus professor of physiology and biochemistry/biophysics at UCSF, where he studied neuroscience. The character of Harold Jameson, U.C.S.F. biophysicist and mountaineer in the film K2, is based on Reichardt, though the events of his actual 1978 K2 attempt with Jim Wickwire bear little resemblance to the plot of the film.

K2, at 8,611 metres (28,251 ft) above sea level, is the second-highest mountain on Earth, after Mount Everest at 8,849 metres (29,032 ft). It lies in the Karakoram range, partially in the Gilgit-Baltistan region of Pakistan-administered Kashmir and partially in the China-administered Trans-Karakoram Tract in the Taxkorgan Tajik Autonomous County of Xinjiang.
