Slide Show: Stopped in Time

Harold Edgerton, a professor of electrical engineering at the Massachusetts Institute of Technology, invented the strobe flash in the nineteen-thirties. Photographers could use the device to stop the appearance of movement in their images, and it changed the course of photography. Michael Hoppen Gallery’s latest exhibit, “Dr. Harold Edgerton: Abstractions,” shows how Edgerton experimented with his own invention.
