Engineering Hall of Fame:
John
V. L. Hogan and the Birth of Radio and Radio History
By
Michael N. Geselowitz
What do technical
professional society officers, engineers interested in technological
history, and the listening audience of New York's classical radio
station WQXR have in common? In the
language of market researchers, "their demographic tends to skew
old." More than that, though, they also share a Wunderkind by the name of John Vincent
Lawless Hogan, who played a formative role in and among each of these
groups.
Even now, in our age of rapidly changing technology
mastered by the 20-somethings of Silicon Valley and Silicon Alley, new
technical fields are growing out of existing disciplines with existing
professional structures that are headed by éminences grises. In
fact, it is possible to hold discussions about which of several
60- and 70-year-old engineers "invented the Internet."
The
IEEE History Center is often approached with the question of who
invented this or that. As historians, we try to explain that
invention is a complicated, multifaceted process seldom undertaken by individuals in isolation. Unfortunately, this answer
is usually unsatisfactory. As you'll soon read, John V. L. Hogan was a pioneer here as
well.
It is difficult for us
to remember that at the beginning of the 20th century, when radio and
electronics were being born, there were no "grand old men" — or
women — for new
practitioners to follow, look up to or emulate. In 1912, the Institute
of Radio Engineers (IRE) was born. One of the predecessor
organizations of IEEE, IRE was the result of a merger of two
organizations: the Boston-based Society of Wireless Telegraph Engineers
(SWTE) and The Wireless Institute (TWI), based in New York. At the
meeting to discuss the merger, TWI was represented by 33-year-old Robert
Marriott and 25-year-old Alfred Goldsmith. Incredibly, SWTE was represented
by John V. L. Hogan, who was only 22!
After the merger, Marriott became the
first President of IRE. The organization's board consisted of several
fellow 30-somethings, while Goldsmith was named editor of the society's
new journal, Proceedings of the IRE.* Likewise, Hogan became one
of the managers (what we might today call a
"director-at-large"). Goldsmith was not to become President of
IRE until 1928, when he was 42. Hogan, however, became President in 1920
at the age of 30, making him the youngest person ever to serve as President
of the IEEE or either of its predecessor organizations. Who was this
precocious individual?
John V. L. Hogan was
born in Bayonne, New Jersey on Valentine's Day in 1890. His childhood
coincided with the beginning of the heyday of radio hobbyists, and by
age 12 he had built his first amateur radio station. In 1906 he managed
to secure a laboratory assistant position, working under Dr. Lee De Forest, a
local engineer and entrepreneur experimenting with the audion, a
three-element vacuum tube he had just invented. At his boss's
suggestion, Hogan went to De Forest's alma mater, Yale, where he
studied mathematics and electrical physics from 1908 to 1910.
In 1910, he left school
to work for Reginald A. Fessenden and the National Signaling Company as
a telegraph operator at the famous Brant Rock station. It was during this
time that he became involved in SWTE. While at National, he helped
develop Fessenden's first patent on the crystal detector (issued in
1910). He is also credited with the invention of the "rectifier
heterodyne." An associate had observed some peculiar effects when a
special transmitter was being operated while the station was receiving
messages. Referring back to some of the work he did at Yale, Hogan
succeeded in increasing the sensitivity of the radio receivers
significantly.
Fessenden then made Hogan
a supervisor for the Bush Terminal Station project in Brooklyn, New York. There he developed
what is perhaps the first ink tape siphon for recording transatlantic radio
signals, using an audion amplifier. His relocation to New York also made
him the logical liaison for SWTE in its merger with TWI to form IRE. IRE
made him a Fellow in 1915 and, as mentioned, President in 1920.
In 1921, after several
important engineering management positions, Hogan opened his own
consulting practice. At this point radio was a mature enough field to
have a past and to have senior members of the profession who could argue
about who invented it. Only 31, Hogan thought it important
that young practitioners coming up in the field appreciate the past
of their technology. He began work on a primer of sorts; The Outline of Radio
was published in
1923. Hogan insisted on including a history of radio technology as the
first chapter. In it, he made the
following astute observation, which would be repeated 80 years later by an
IEEE History Center staffer in response to a reference request:
"Scientists in
many countries have helped in the development of radio signaling; but
neither the United States, Great Britain, France, Italy, nor Germany
need be unduly modest over the contributions of its workers. A
chronological record of the art's advances will skip from one country to
another; a bit suggested by one man here has been adopted and improved
upon by another investigator there, and the combination of ideas has
marked an additional step forward. Radio as we know it today is no
single invention or discovery; modern instruments utilize the novelties
devised by a host of engineers and physicists whose work extends over
the past 70 years or more."
Hogan was not done
with innovations, however. Always interested in tonal quality, he built
one of the first high-fidelity radio stations. First licensed as W2XR in
1934, this 250-watt experimental station would eventually become New
York City's 10,000-watt classical station, WQXR. So, as you
listen to Brahms and Rachmaninoff while your grandchildren roll their
eyes, remember that then Hogan was still only 44.
* The year 2002 is
also the 90th anniversary of IRE and of Proceedings of the IEEE,
which arose from the earlier journal. Look for special celebrations all
year in Proceedings, including a commemorative article on Alfred Goldsmith in
the February 2002 issue: http://www.ieee.org/organizations/pubs/proceedings/prev02.html.
