Frank Sacherer
Franklin James "Frank" Sacherer (born May 22, 1940 in San Francisco , † August 31, 1978 in the Grandes Jorasses in the French Alps ) was an American physicist and climber.
Sacherer made his bachelor's degree at the University of California, San Francisco and studied from 1960 at the University of California, Berkeley , where he received his doctorate in 1968 with Lloyd Smith on the theory of particle accelerators . In 1967 he went to CERN in Geneva , where he was permanently employed in 1970 and theoretically worked on stochastic cooling (for which he was a leading expert) and collective effects in particle beams, which in many cases limit the achievable luminosity . He was involved in the super proton synchrotron (SPS), with which the W and Z bosons were later discovered (Nobel prizes for Carlo Rubbia and for stochastic cooling for Simon van der Meer ).
As a climber, he was a legend in the climbing scene in the Yosemite Valley during his active time from 1960 to 1965 , including some first ascents (FA) and in particular free first ascents (FFA), for example the Salathé route on Half Dome (FFA 1964, with Bob Kamps, Andy Lichtman), the East Buttress at Middle Cathedral Rock in Yosemite (FFA with Ed Leeper 1965). The Sacherer Column (Sacherer Crack) on El Capitan is named after him. (Sacherer, Mike Sherrick 1964). In 1966 he had to give up the activities (and previously climbed mostly only on weekends) because he was busy with his dissertation and then his career as a physicist. During his time at CERN, he climbed in the Alps. In 1978 he got into a storm with the young theoretical physicist Joseph Weis in the route The Shroud (Le Linceul, an almost vertical ice field near the Walker pillar in the north face) in the Grandes Jorasses while descending and died together with Weis. Its ashes were scattered in the Yosemite Valley near its favorite climbing routes.
The Frank Sacherer Prize of the European Physical Society for young scientists in the field of particle accelerators is named after him.
