Elsie Eaves (May 5, 1898 – March 27, 1983) was a pioneering American female engineer,^[1] the first female associate member of theAmerican Society of Civil Engineers (ASCE), and a founding member of the American Association of Cost Engineers (now AACE International; theAssociation for the Advancement of Cost Engineering).^[2]

Eaves was born inIdaho Springs, Colorado, and earned hercivil engineering degree at theUniversity of Colorado at Boulder in 1920.^[1]

In 1918, Eaves was elected as the first female president of the school’s student engineering society, the Combined Engineers, such an unusual occurrence that the news received national coverage in engineering publications.^[3] She supportedLou Alta Melton andHilda Counts in creating theAmerican Society of Women Engineers and Architects in 1919.^[3]

At the age of 22, she was the first woman to earn a degree in civil engineering from the University of Colorado at Boulder.^[4] Eaves began her engineering experience before she received her university degree.

Eaves was a draftsman for the United States Bureau of Public Roads in Denver, Colorado, and then theDenver and Rio Grande Western Railroad Company.^[5]

She joined theWomen's Engineering Society (at the time the only organisation for women engineers in the world) in 1925, and continued as a member throughout her career.^[6]

In 1926 Eaves started working forMcGraw-Hill inNew York City for theEngineering News-Record (ENR) Department. She was also a publication and sales manager of the McGraw-Hill Construction Daily.^[7] In 1927, she was the first woman admitted to full membership to the American Society of Civil Engineers. In 1945, she became the manager ofBusiness News.

In 1929, Eaves originated and compiled the first national inventory of municipal and industrial sewage disposal facilities.^[8] Next, she compiled statistics on needed construction, which helped revitalize the construction industry during the Great Depression. After World War II, Eaves organized and directed ENR’s measurement of “Post War Planning” by the construction industry that was used as the official progress report of the industry.^[8]

In total, she was associated with McGraw-Hill's Engineering News-Record, a weekly trade publication, for 37 years.^[1]

She retired in 1963 but continued practicing as an adviser to the National Commission on Urban Affairs on the subject of housing costs. She advised the International Executive Service Corps about construction costs inIran.^[9] In 1967, Eaves attended the secondInternational Conference of Women Engineers and Scientists (ICWES) inCambridge, UK,^[10] and in 1972, she wrote the obituary for fellow engineer,Ruth Shafer, chair of the first ICWES.^[11]

In 1974, she received the George Norlin Silver Medal, the highest alumni award given by the University of Colorado and, in 1979, she was the first woman to receive an honorary lifetime membership to the American Association of Cost Engineers.

Eaves was honoured with the Fellow award at the 1980Society of Women Engineers National Convention (Conference) in Cherry Hill, New Jersey, having been a member of the organisation since 1950.^[12]

Elsie Eaves died March 27, 1983, atSt. Francis Hospital inFlower Hill, New York, aged 84.^[13][14]
