The war made aerial reconnaissance a strategic requirement for the Allies. Edgerton抯 nighttime
aerial flash technology was an effective tactical means of meeting this requirement. This is
precisely why Major Goddard first approached him, and how Edgerton eventually got involved
in the war. He was 揺xtracted?from his familiar, calm laboratory setting and taken into the
battlefields in England and Italy, where conditions were uncontrolled and tumultuous. This

INCREASE IN SCALE AND MAGNITUDE
Having become involved in the war, the most immediate effect Edgerton抯 work experienced
from the war was new technical requirements. Power was now the name of the game. Prior to
the war, the aim of Edgerton抯 strobe photography was to capture motions which occurred too
fast to be observable to the naked eye. His chief concerns were accuracy of triggering and flash
duration. Aerial reconnaissance, however, called for flashes 100 times more powerful than those
before the war. The flashes had to sufficiently illuminate terrain thousands of feet away from the
plane as opposed to a milk drop inches away from the camera. Thus, power, and consequently
weight, of his flash units increased tremendously as a direct result of the war.
BROADENING OF APPLICATIONS
Edgerton抯 newly formed link with the military also gave rise to new applications for his
electronic strobe. The nighttime aerial strobe was the first in a number of wartime applications.
Other examples included ballistics photography and aircraft beacons. The aerial selectronic flash
may also have led to his development of the side-scan sonar. Hence, an obvious effect of the war
was the ensuing broadening of applications.
NEW AREAS OF RESEARCH
The war also had an indirect, but not insignificant, influence on Edgerton抯 work in the form of
the relationships it engendered. The war formed a network between parties and organizations
that began working together for the same cause. The aerial strobe project and Los Alamos were
two separate entities that linked up because of their respective relationships with Raytheon. It
was because of this connection that Los Alamos was able to tap the expertise of Edgerton and his
associates. These relationships represented the beginning of a new research realm for Edgerton.
A combination of MIT抯 anti-military attitude and National Security Policy immediately after the
war also facilitated the founding of EG&G, which was to undertake this new dimension of
research and eventually become a major part of Edgerton抯 legacy.
A KEY FORCE IN EDGERTON扴 LIFE
In conclusion, war is a unique state of affairs that impacts all aspects of society. World War II抯
influence on Edgerton抯 work cannot be traced to one particular line or trajectory. The war
changed everything from his work environment to the actual technology he researched. There is
no doubt however, that it was a pivotal force in the life of the Harold E. Edgerton.

HOW WE CONDUCTED THE RESEARCH
A significant portion of our research was conducted at the MIT archives, where we examined all
of Edgerton抯 notebooks and materials that he had compiled and donated to MIT. The most
challenging aspect of a project history on Edgerton is being able to focus on a single specific
topic. Edgerton had such a prolific career that it is hard to choose a single path to study. By
searching through these primary sources we were able to narrow our topic to events surrounding
World War II, which the MIT Archives had well documented. We also interviewed Edgerton抯
student, Professor Kim Vandiver, and Dr. James Bales of the Strobe Lab. They gave us insight
on who Edgerton was on a personal level and also shed light on the technical side of Edgerton抯
tools. All of the equipment demonstrated during the presentation were borrowed from the Strobe
Alley.
永利国际娱乐注册送56 ACKNOWLEDGEMENTS
We would like to thank Professor David Mindell, Professor George Pratt, and Eden Miller for
their guidance and input this term, Professor and Dean Kim Vandiver for talking with us about
Doc Edgerton, Dr. James Bales for providing us with information and the use of equipment, and
the staff at the MIT Archives for all their help with our research.
