Herbert S. Bridge dating history

Details

Herbert Sage Bridge (1919-1995) was an American physicist who developed the first instruments to measure plasma in interplanetary space and made significant contributions to cosmic ray research. He earned his PhD in physics from MIT in 1950 under Bruno Rossi's supervision after working on wartime projects at Princeton and Los Alamos Laboratory. His early research focused on cosmic rays. Beginning in 1958, Bridge developed the modulated-grid Faraday cup with Rossi, creating the first instrument capable of detecting dilute space plasma. The instrument flew aboard Explorer 10 in 1961 and was adapted for plasma science experiments on multiple spacecraft, including the Voyager program and Parker Solar Probe.
