The new television set, 1949.

Argonne National Laboratory physics research associate Caroline Herzenberg using the Electronic Measuring Machine¹ to analyze nuclear particle tracks on rolls of 35 mm film taken of the ten-inch bubble chamber² mounted inside a superconducting magnet³ at Argonne's 12.5 GeV⁴ Zero Gradient Synchrotron⁵ particle accelerator facility (1967).
It was a highly customized piece of film scanning equipment, automatically plotting the selected tracks and digitizing the information for later computer analysis. During the first experimental run, 476,000 pictures were obtained in a 25 day period!
