Dr. A. Hoyt Taylor,
From Dunlap’s 100 greatest men in radio Pages
194-196 |

Albert Hoyt Taylor, radio engineer, investigator of ethereal
phenomena and pioneer in radar, was graduated in 1899 from Northwestern
University with a B.S. degree. He opened his career as a teacher
and was appointed instructor of physics and electrical engineering at Michigan
State College, 1900-03; then instructor at the University of Wisconsin,
1903-05; assistant professor, 1905-08. From the Imperial University
at Goettingen, Germany, he obtained a Ph. D. in 1909, and served as professor
of physics at the University of North Dakota, 1909-17.
Taylor was a pioneer in the
study and development of short waves and concentrated on that phase of
radio when he joined the government service in November, 1917, commissioned
a lieutenant in the United States Navel Reserve. In 1918, he became
a lieutenant commander; in 1919, commander. As superintendent of
the Radio Division of the United States Naval Research Laboratory, Anacostia,
D.C., he studied polarization of electric waves, ‘round-the-earth echoes
or multiple signals and the structure of the upper atmosphere. As
the result of his experiments in 1925, the “radio deflecting roof” revealed
two waves – one “horizontal” traveling the earth’s surface, the other revounding
from the sky. The “radio roof” or Heaviside theory was further confirmed.
Taylor, regarded as one of the
government’s most skilled experts in radio research and engineering, was
awarded the Liebmann Memorial Prize by the Institute of Radio Engineers
in 1927 for his short-wave work and application of piezo crystals in transmitting
circuits. He also designed special radio equipment for aircraft.
World War II found him engaged in important radio research at Anacostia,
with all his experience of the First World War and of the intervening years
to enhance the value of his work.
Serving as president of the
Institute of Radio Engineers in 1929, he once remarked, “I might
be classed as 25 per cent physicist, 25 per cent inventor, 25 per cent
naval officer and 25 per cent radio engineer.”
Taylor’s important work in the
study of radio echoes and the structure of the upper atmosphere contributed
greatly to the development of radar – radio detecting and ranging.
Tracing the United States Navy’s
early development of radar, the Navy Department on May 23, 1943, called
attention to the fact that on mid-September of 1922 Taylor and Leo C. Young,
working in the Naval Aircraft Laboratory, Anacosta, observed that certain
radio signals were reflected from steel buildings and metal ships.
They also noticed that ships passing by a transmitter and receiver attuned
to certain frequencies produced a definite interference pattern.
Between 1925 and 1930 the reflection
phenomenon was used to measure the height of the Kennelly-Heaviside layer.
Taylor and Young performed this work in conjunction with Dr. Gregory Breit
and Dr. Merle A. Tuve, of the Carnegie Institute. Their associates
during this period included Louis A. Gebhard, M.H. Schrenck, L. A.
Hyland and later Robert M. Page and Robert C. Guthrie.
A report prepared by Taylor
on “radio-echo signals from moving objects” was submitted on November 5,
1930, to the chief of the Bureau of Engineering, Navy Department.
As a result, on January 19, 1931, the Bureau assigned the Naval Research
Laboratory the problem of investigating the use of radio to detect the
presence of enemy vessels and aircraft. Special emphasis was placed
on the confidential nature of the problem.
Many conferences with Army and
Navy officers were accompanied by demonstrations during the ensuing years.
The importance of having radar tested with the fleet was realized as a
result of studies made during the tactical maneuvers of the fleet in the
Pacific during the autumn of 1936. As a further step, the Naval Research
Laboratory on February 17, 1937, conducted a demonstration for naval officers
of radar detection of aircraft. Also in 1937 the first radar equipment
was taken to sea. The next year was spent in designing and building
a practical shipboard model which was installed on the U.S.S. New York
late in 1938.
The radio echoes which A. Hoyt
Taylor heard coming back to earth from outer space were echoes that challenged
scientists to make use of them. Once that was done, radar added a
new dimension to the science of radio.
As Chairman of the Medal for
Merit Board, Cordell Hull, Secretary of State, presented the Medal of Merit,
awarded to civilians for outstanding services in the war, to Taylor with
this citation: (March 28, 1944)
For exceptionally meritorious
conduct in the performance of outstanding services in the line of his profession
as member of the staff of the Naval Research Laboratory. Undiscouraged
by frequent handicaps, Dr. Taylor labored tirelessly in the course of intensive
research and experimentation which eventually resulted in the discovery
and development of radar. His foresight, technical skill and steadfast
perserverance contributed in large measure to the timely introduction of
a scientific device which has yielded the United States Navy a definite
advantage over her enemies during the present war.
