Harold Eugene Edgerton born April 6th in Fremont,
Nebraska. Son of Mary Nettie (Coe) and Frank Eugene Edgerton first of three
children. Over the next dozen years the Edgerton family moved a total of four
times, finally settling in Aurora, Nebraska.
Attends junior and senior high school in Aurora. Learns
photography from an uncle and sets up a dark room in his home.
Works summers at the Nebraska Power and Light Company.
Develops an interest in electrical generation and in 1921 enrolls at the
University of Nebraska in Lincoln.
Receives B.S. in electrical engineering from UNL.
Works for another electric company this time in
Schenectady, New York. Again continues his study on the turbines that produce
Enters the Massachusetts Institute of Technology (MIT). In
his graduate studies uses the strobe light to study whirling rotor engines. By
controlling the frequency of strobe flashes synchronized with the spinning
rotors, he is able to see rotors clearly.
Receives M.S. in electrical engineering from MIT. From
this time forward he becomes a faculty member at the Institute.
Marries Esther May Garrett also a Nebraska native. They
have three children: Mary (b. 1931), William (b.1933), Robert (b.1935).
Develops and perfects the stroboscope for use in both
ultra-high-speed and still (or stop-motion) photography. This discovery is
announced in the May issue of Electrical Engineering. Forms partnership with
former student Kenneth J. Germeshausen, an MIT research affiliate, to develop
the stroboscope for various applications. Receives D. Sc. in electrical
engineering from MIT.
Begins taking high-speed photographs of familiar
activities that move at speeds beyond the ability of the human eye to perceive.
The photographs appear in both popular and technical publications.
Applies for U.S. patents for the stroboscope. Over the
next thirty-five years applies for 45 patents. Three of his photographs are
included in a display in the Royal Photographic Society's annual exhibition in
This is the first time Edgerton's work is exhibited.
Herbert E. Grier, another former student of Edgerton's,
joins the partnership of Edgerton and Germeshausen. They continue to develop
ultra-high-speed photography, and unique stroboscopic effects. Ten of Edgerton's
high-speed photographs are included in the Royal Photographic Society's annual
exhibition. Edgerton, Germeshausen and Grier are awarded the society's Bronze
Medal. Edgerton's first photography award.
Begins life long association with Life magazine
photographer, and fellow MIT electrical engineering graduate Gjon Mili. The
Photograph "Coronet", taken by Edgerton, is chosen by Beaumont Newhall for
inclusion in the first photographic exhibition held at the Museum of Modern Art
in New York City.
Perfects multiflash photography of athletes in action. Unsuccessfully attempts to sell the concept of electronic flash to major U.S. camera manufacturers. Contacts sports photographers and offers them his services and equipment. By 1940, sports photography is revolutionized by Edgerton's technique, which allows the camera to capture high-speed motion and preserve an unprecedented degree of detail. Electronic flash photographs of sports events are regularly published in major newspapers after 1940.
The U.S. Army Air Force commissions Edgerton to design a strobe lamp powerful enough to be used for aerial photography at night.
First book, "Flash! Seeing the Unseen by Ultra High Speed Photography," co-authored with James R. Killian, Jr., is published to critical acclaim. E.F. Hall, reviewing Flash! in the New York Times, says, "This whole book....covering the fields of nature, sport, and industry, is a compilation of magic and of things undreamed, calculated to excite the most sluggish mind."
Works at MGM Studios in Hollywood, demonstrating how to use high-speed photography to make movies. He collaberates with Pete Smith on the Academy Award-winning film short, Quicker Than a Wink.
Serves in Italy, England, and France as a technical representative for the US Army Air Force. Directs use of the strobes for nighttime aerial reconnaissance photography, providing vital intelligence information about troop movements in enemy territory. They are used in the nights immediately preceding the D-day invasion of Normandy, during the Battle of Monte Cassino, and in campaigns in the Far East.
Receives the medal of Freedom from the War Department in recognition of his achievements in developing nighttime aerial photography during the Second World War.
With partners Germeshausen and Grier, forms Edgerton, Germeshausen, and Grier, Inc. (now EG&G, Inc.), a company specializing in electronic technology. As prime contractors for the Atomic Energy Commission, they design and operate systems that time and fire US nuclear bomb tests. Edgerton and colleagues will invent a camera (the Rapatronic) capable of photographing nuclear explosions from a distance of seven miles.
The first of his many articles for National Geographic magazine is published. "Hummingbirds in Action" contains high-speed photographs that illustrate for the first time the wing movement and flight patterns of these tiny birds.
Begins long association with French underwater explorer Jacques-Yves Cousteau, accompanying him on numerous expeditions aboard the research vessel Calypso. They explore and photograph sea floors from the Mediterranean to Lake Titicaca in the Andes Mountains. To position underwater cameras on these expeditions, Edgerton designs a "pinger" device that attached to a submerged camera. Sound waves, emitted from the pinger and returning as echoes from the ocean floor, indicate how close the camera is to the bottom. On these expeditions, Edgerton also experiments with the side-scan sonar, an acoustic device used to locate objects lying on the ocean floor.
Aboard the research vessel Chain of the Woods Hole Oceanographic Institution, accompanies expedition to Puerto Rico to photograph the ocean floor. Using his new sonar "thumper," a device capable of subbottom penetration of the sea floor, Edgerton and colleagues locate rocks thought to be the first specimens ever obtained from the deepest layer of the earth's crust.
Designs the "boomer," a sonar device useful for continuous seismic profiling of the bottom of the sea.
With colleagues at MIT, develops technique, using stroboscopic lighting and special cameras, for taking motion pictures of the blood flow in the capillaries of humans.
With Greek archaeologists, goes on first of several sonar expeditions in search of ancient Helice in the Gulf of Corinth, a city submerged by earthquakes and volcanic eruptions in about 373 BC.
Receives appointment as Institute Professor at MIT, an honor awarded to distinguished faculty members upon nomination by their colleagues on the faculty.
Using his penetrating sonar, locates the Mary Rose, an English warship sunk during the reign of Henry VIII.
With colleagues, designs an elapsed-time photographic system capable of photographing underwater events, using strobe lights for illumination. This system makes possible the observation of underwater events normally too slow to be seen, such as the movement of sand dollars or sea urchins.
Using side-scan sonar, Edgerton and colleagues locate the sunken Civil War battleship USS Monitor, lost since 1862, off Cape Hatteras, North Carolina. The battleship lies upside down in 220 feet of water.
With eighty other scientists, goes to Akjoujt in Mauritania to record changes in light and color during one of the longest solar eclipses (some seven minutes) in this century.
Receives the US national Medal of Science, awarded by President Richard M. Nixon at the White House.
To honor Harold and Esther Edgerton for many years of hospitality and encouragement to the students and faculty, the MIT Corporation establishes the Edgerton Fund to support younger faculty and student research at MIT.
Ends association with EG&G, Inc., and becomes emeritus chairman of the board.
Permanent display of camera strobe equipment and photographs is installed at the Plainsman Museum in Aurora, Nebraska.
