The Invisible Visible

Harold Edgerton SM ’27, ScD ’31, Faculty

Edgerton spent his life making the invisible visible. His electronic stroboscope created some of the 20th century’s most iconic images: a drop of milk frozen in a perfect crown, a bullet speeding through an apple. But he also received the Medal of Freedom for his work on aerial night photography during World War II and illuminated the ocean with advances to sonar and underwater photography.
