He was a professor of electrical engineering at the Massachusetts Institute of Technology, also known as MIT. Many people called him "Papa Flash" because of his work with light. He is famous for turning the stroboscope into a common tool. A stroboscope is a device that makes very fast flashes of light. These flashes help us see things that move too quickly for the human eye. His work was so beautiful that many of his photos are now in art museums.

His special way of working involved using short electronic flashes. This technique allowed him to capture fast events in a single moment. For example, he could photograph a bullet hitting an apple. He also took pictures of balloons as they burst into pieces. In 1936, he worked with an expert named May Rogers Webster. Together, they showed that a camera could capture a hummingbird's wings. The bird's wings beat 60 times every second. To catch this, the camera needed an exposure of one hundred thousandth of a second.

Edgerton's journey in science began in Nebraska. He was born in Fremont on April 6, 1903. His father was a lawyer and a journalist. Edgerton went to the University of Nebraska for his first degree. He earned that degree in electrical engineering in 1925. Later, he went to MIT to study more. He earned a master's degree there in 1927. By 1931, he finished his doctoral thesis at MIT. He used stroboscopes to study motors for his research.

Edgerton also helped develop side-scan sonar. This technology helps people find things on the ocean floor. He worked with the explorer Jacques Cousteau to find shipwrecks. His tools helped find the battleship USS Monitor. He even joined a search for the lost city of Helike in Greece.

Today, we can still see the impact of his work. His lab at MIT was called "Strobe Alley." It was a place where students loved to tinker and invent. He was a very kind teacher who loved his students. To remember him, a science center was built in his hometown. The Edgerton Explorit Center opened in Aurora, Nebraska, in 1995. It is a place where people can learn through hands-on science. His work reminds us that science can be both useful and beautiful.
