Thomas Hope Johnson (September 12, 1899, Coldwater, Michigan[1] – February 25, 1998, Denmark, Maine) was an American physicist, known for his research on cosmic rays.
[1] At the Bartol Research Foundation, Johnson and colleagues counted cosmic rays at several different latitudes and altitudes.
[3] According to Nicholas P. Samios:[3] He and his associates sent up balloons, sometimes taken for unidentified flying objects, with film to record cosmic rays at points from sea level to mountain tops as high as 10,000 feet in Colorado, Mexico and Peru.
[4] When the USA entered WW II, Johnson joined the staff of Aberdeen Proving Ground's Ballistics Research Laboratories.
[1] His ballistics research involved measuring blast forces for bombs and using microwaves to record projectile velocities in artillery bores.
