Biographical Sketch
Halvor Olsen Hem was born August 14, 1863, in Saude,
Norway, to Ole and Aste Hem. H.O. Hem was born into a family of engineers and mechanics, and before the age of
fifteen had designed numerous mechanical devices including scales, steam engines, and sewing machines. In 1882, H.O. Hem came to the
United States where he became an engineer with the H.N. Strait Manufacturing Company of Kansas City, Missouri. It was in 1890 when he
became the chief engineer, superintendent and vice-president of the company. H.N. Strait Manufacturing Co. produced scales under the
name Monarch for twelve years under H.O. Hem. In 1902 the company was sold to Fairbanks, Morse and Company where H.O. Hem created a
complete line of scales. H.O. Hem remained there until 1915 when he became a consultant to the Toledo Scale Company, and in 1928 he became
the chief engineer of Toledo Scale. Some of his developments in scales were in the area of heavy capacity, mechanical devices for
World War I and II, wind tunnel measuring systems, and the automobile industry.
During his tenure as an engineer, H.O. Hem received various awards and honors. He received the John Price Wetherill medal in 1932 for
his perfection of pendulum scales. In 1936 he received an honorary Doctor of Science degree from the University of Toledo. H.O.
Hem was also part of many associations and organizations. One such group was the Yards and Terminals Committee 14 of the American
Railway Engineering Association, which determined the rules and regulations for scales and their installation. He was also a member of
the American Society of Civil Engineers, American Society of Mechanical Engineers, American Railway Engineering Association, and the
National Scale Men’s Association.
H.O. Hem retired from
the Toledo Scale Company in 1947, but he still helped the company as a consultant. H.O. Hem was married twice, first to Lillian with
whom he had two children, H. Warren and Verona, and second to Helen Vaughan. He died on November 11, 1952.
Halvor Warren Hem was born on September 25, 1892, to H. O. and
Lillian Hem in Kansas City, Missouri. H.W. Hem followed in his fathers footsteps with his passion for creating scales and mechanical
devices. He held over 100 patents by the time he was sixteen years old. He also came to the Toledo Scale Company where he became
the chief design engineer. While at Toledo Scale, he designed and oversaw the creation of many important scales. H.W. Hem
retired from Toledo Scale in 1960 (1963?) after 31 years of service.
H.W. Hem was married to Madeleine and had three children, Clarice, Paul, and H.W. Jr. H.W. Hem passed away on February 3, 1988 at the age of 95.
Scope and Content Note
The papers of H.O. and H.W. Hem consist of 5 linear feet
and broken into four primary series: blueprints and engineering drawings, photographs, publications, and miscellaneous H.O and H.W.
materials. These materials give an in-depth description of the engineering side of the Toledo Scale Company during the two Hems’
terms as chief engineers. The collection consists of blueprints and drawings, scale newsletters, photographs and catalogs of scales,
instructions, other companies’ products, sales information, articles, and correspondence materials documenting the daily engineering
of scales.
The four series are arranged alphabetically then
chronologically. Also, those materials specifically designated by H.O. or H.W. have been arranged first by father (H.O.) then by son
(H.W.), followed by those materials without designated ownership.
Many items may be duplicated in the Toledo Scale Collection, MSS-153.
