Harold Edgerton

Harold Edgerton (1903–1990) was an American electrical engineer and photographer who pioneered electronic strobe photography and helped develop side-scan sonar.

Electronic flash: A light source that produces a brief, intense flash by discharging electrical energy through a gas-filled tube. Edgerton developed practical high-speed electronic flashes that could freeze rapid motion.
Milk Drop Coronet: A 1936 photograph by Harold Edgerton showing a crown-shaped splash formed by a falling milk droplet. This iconic image shows how a precisely timed flash can expose a split-second fluid shape.
MIT: A private research university in Cambridge, Massachusetts, founded in 1861. Edgerton spent his academic career at MIT, where his strobe research began.
Flash photography: Photography that uses a brief artificial light source to illuminate a scene during exposure. Edgerton’s electronic flash made flash photography suitable for extremely short exposure times.
MIT Museum: A museum at the Massachusetts Institute of Technology devoted to science, technology, and art. Its collection preserves Edgerton’s instruments, photographs, and demonstrations.
Stroboscope: A device that emits periodic flashes to make rapidly moving objects appear stationary or slowed. His repeated flashes made rotating machinery appear motionless for study and photography.
Bullet Through Apple: A high-speed photograph by Harold Edgerton capturing a bullet passing through an apple. The image demonstrates his ability to record destructive motion at a chosen instant.
Gjon Mili: An Albanian-American photographer known for using stroboscopic techniques to depict movement. Mili collaborated with Edgerton and brought strobe imagery into artistic photography.
Motion analysis: The systematic measurement and interpretation of movement over time. High-speed images let engineers inspect motions invisible to ordinary observation.
Photographic art: Creative practice that uses photography to make images with aesthetic or expressive intent. Edgerton’s scientific images entered galleries and shaped ideas about photography’s artistic possibilities.
