Biography
Harold Farley Elliott was born in Durango, Colorado, on June 17, 1892, to Wilbur S.
Elliott and Henrietta Farley Elliott. Elliott’s only sibling, Jean Elliott, was born in 1895.
Elliott grew up in Prescott, Arizona and graduated from Prescott High School in 1911.
He then attended Stanford University, where he graduated in 1916 with his A.B. in
Mechanical Engineering and in 1925 with his Master’s degree in Electrical Engineering.
From 1916 to 1922, Elliott worked at the Federal Telegraph Company as a Chief
Draftsman, Production Manager and Engineer in Charge of the design of high power
radio transmitting equipment. From 1922 to 1925, he served as the Consulting Engineer
in charge of designing the transmitting equipment for the Trans-Pacific project (“the
Chinese project”) for the Federal Telegraph Company and its subsidiary, the Federal
Telegraph Co. of Delaware. Federal Telegraph Company had planned to construct four
radio transmission stations to be located at Shanghai, Pekin (Peking or Beijing), Canton
and Harbin, China. Unfortunately, in 1924 the Chinese project came to a standstill.
According to Elliott, the instability of the Chinese government, the beginning of short
wave radio and conflicts between the Federal Telegraph Company and R.C.A. caused the
Chinese project to be delayed. Elliott wrote “It was not until 10 years later that R.C.A.
finally established a short wave circuit to Shanghai.”
In early 1927, Elliott began designing and producing radio receivers for home use for the
Victor Talking Machine Company. From 1929 through 1931, he served as a consulting
engineer at that company. In 1937, he demonstrated his home radio set with clock and
push button tuning to Paul Galvin of the Galvin Manufacturing Corporation (Galvin).
This demonstration led to a licensing agreement for Galvin’s exclusive use of Elliott’s
tuner in auto sets and the production of a push button automobile radio. According to
Elliott, the licensing agreement “worked out very satisfactorily for all parties concerned.”
While working with Galvin, he developed other radio apparatus, such as a portable
table model radio, radio tuners for military communication equipment, and a solenoid
(or motor drive) for mechanical push button tuners. When describing his working
relationship with Galvin, Elliott wrote “Over an eight year period every request for help
has been met in good faith and without reservations. No expenditure in time or money
has been spared to find a satisfactory solution and every problem has found a successful
answer.”
In February 1942, Dr. Frederick E. Terman convinced Elliott to join the Radar CounterMeasures Laboratory developing at the Massachusetts Institute of Technology.
(Eventually the laboratory moved to Harvard University and became known as the Radio
Research Laboratory.) While Elliott spent 1942 through 1945 conducting war research
at the Radio Research Laboratory, he still continued to work on his radio apparatus
developments for Galvin.
During much of his career, Elliott independently designed, developed, and marketed
7 February 2013

various radio apparatus, such as push-button, remote control, and clock control
mechanisms for radio receivers and transmitters. His work resulted in over 80 U.S.
patents, issued from 1920 through 1966.
From 1953 into the early 1960s, Elliott worked as a consultant at the Hewlett-Packard
Company on technology related to digital printers and clocks.
In addition to his electrical engineering work, Elliott was an accomplished photographer.
During his undergraduate studies at Stanford, he managed the Campus Photo Shop and
was the student manager of the 1916 Quad (the student yearbook). (Elliott appears to
have been a contemporary of Stanford photographer Berton W. Crandall.) He continued
with his photography throughout his lifetime, taking photographs for both professional
and personal purposes. During the 1950’s, Elliott’s work was shown in multiple
photography exhibits, including an exhibit held at the Stanford University Art Gallery.
He also spoke about his photography at local camera clubs.
Throughout his lifetime, Elliott remained connected with Stanford University. He
worked with or corresponded with other Stanford University electrical engineering
alumni throughout his career, such as Ralph R. Beal, James Arthur Miller, Clinton
H. Suydam, Herman P. Miller, Hans Otto Storm, Dr. Frederick E. Terman, Charles
V. Litton, Bill Hewlett and Dave Packard. Elliott’s personal correspondence refers
to attendance at Stanford University football games and other activities. In his later
years, he served as a part-time lecturer in the Engineering Department and on the 50th
Anniversary Stanford Engineering Scholarship Fund Committee.
Elliott married 1924 Stanford University graduate and accomplished musician Winifred
Estabrook. One common interest between the couple was their love of classical music.
Their personal correspondence mentions Estabrook’s musical performances and their
attendance at various music events. In later years, Estabrook acted as his personal
secretary. In 1954, the couple moved into the custom home Elliott had designed at 800
Westridge Drive in Portola Valley, California. Elliott died at age 77 on January 24, 1970
in San Mateo, California. Estabrook died at age 82 on January 20, 1977 in Santa Clara,
California.
Collection Overview
Correspondence, technical drawings, computations, patent materials, photographs,
sketches and notes regarding electrical engineer Harold F. Elliott’s prolific work as an
inventor of various radio apparatus and as a consulting engineer with such companies as
the Federal Telegraph Company, the Galvin Manufacturing Corporation (Motorola, Inc.),
the Victor Talking Machine Co. and the Hewlett-Packard Company, and also during
World War II at the Radio Research Laboratory at Harvard University.
Of particular note is Elliott’s extensive collection of Federal Telegraph Company
documents, such as inter-office correspondence and memoranda, engineering reports

Guide to the Harold F. Elliott Papers (2003-36, History San Jose)
and the technical drawings, accounting worksheets, and other material related to the
transmitting equipment and radio stations designed for the Federal Telegraph Company’s
Trans-Pacific project, as well as numerous technical drawings of his radio tuners,
clocks and assorted parts from his work with the Galvin Manufacturing Corporation.
From his work at the Radio Research Laboratory, Elliott saved previously classified
correspondence, technical manuals, pamphlets and reference notebooks. Separate files
detail the step-by-step process of obtaining patents for over 30 of his radio apparatus
inventions.
The papers also contain a significant amount of personal materials from Elliott and his
wife Winifred Estabrook, including personal correspondence, financial and real estate
records, educational material, and musical performance and art exhibition programs.
Elliott’s interest in photography is well-documented through photography equipment
brochures, photography club circulars, and news clippings regarding Elliott's exhibitions
and talks. Over 1,100 black and white photographs taken by Elliott portray his days at
Stanford University (1911-1916), his inventions, and the landscapes of California and the
American Southwest. Also included are Elliott's plans and architectural drawings for their
residence at 800 Westridge Drive, Portola Valley, California, built in 1954.
The papers have been divided into 13 series, as described below:

Series 3: Interference Testimony and Related Documents
Date Range: 1930-1945
Extent and Location: 4 folders, Box 13 (2003-36-49):
This series contains documents regarding three patent interference proceedings: Radio
Corporation of America v. Radio Engineering Labs., Inc., 293 U.S. 1 (1934), Loy E.
Barton v. Harold F. Elliott (Interference No. 70,658) and Mastney and Williams v. Elliott
(Interference No. 81,126).
The Radio Corporation of America v. Radio Engineering Labs., Inc. documentation
includes Elliott's 1930-1931 research regarding oscillator patents while employed at
RCA-Victor Company, inc. and related notes and correspondence. Note that this court
case has been cited in the more recent Microsoft Corp. v. i4i Limited Partnership et. al.,
563 U.S. ___ (2011) as having established the "clear and convincing" evidence standard
required to overturn an already issued patent.
In Loy E. Barton v. Harold F. Elliott (Interference No. 70,658), Barton claimed that
Elliot's Automatic Gain Control patent application (Serial No. 628,629) interfered with
Barton's Automatic Volume Control with Noise Suppression patent application (Serial
No. 640,946). The documentation includes Elliott's interference testimony and related
correspondence (1935-1937); however, there does not appear to be sufficient information
to determine the outcome of this interference proceeding.

Guide to the Harold F. Elliott Papers (2003-36, History San Jose)
In Mastney and Williams v. Elliott (Interference No. 81,126), Edward J. Mastney (from
Oak Manufacturing Company) claimed that Elliott's Control Mechanism (1941, Serial
No. 424,234, Elliott Cases 25 and 29) interfered with Mastney's Preselecting Mechanism
(1942, Patent No. 2,293,299). It appears that this interference claim was eventually
dropped. A related interference claim (Interference No. 82,100) was also dropped.

In 1937, Elliott demonstrated his home radio set with clock and push button tuning to
Paul Galvin of the Galvin Manufacturing Corporation (Galvin). This demonstration led
to a licensing agreement for Galvin’s exclusive use of Elliott’s tuner in auto sets and the
production of a push button automobile radio. While working with Galvin as a
Consulting Engineer, Elliott developed other radio apparatus, such as a portable table
model radio, radio tuners for military communication equipment and a solenoid (or motor
drive) for mechanical push button tuners. This series includes documents related to
Elliott’s work with Galvin during the years 1937 through 1945 and is divided into six
subseries: Correspondence and Related Documents, Technical Drawings - Tuners, Clocks
and Assorted Parts, Sketches, Blueprints, Oversized Drawings and Related Documents,
Photographs, and Assorted Materials.
