Women Were First Computer Programmers

Saturday, March 24, 2012

In this excerpt from "The Computer Boys Take Over," historian Nathan Ensmenger explains that the first computer programmers were women because managers expected programming to be low-skill clerical work. They were wrong: The job required skill and ingenuity and these women persevered.




(WOMENSENEWS)--The low priority given to programming was reflected in who was assigned to the task. Although the ENIAC (the first general-purpose electronic computer) was developed by academic researchers at the University of Pennsylvania's Moore School of Electrical Engineering, it was commissioned and funded by the Ballistics Research Laboratory of the U.S. Army.

Located at the nearby Aberdeen Proving Grounds, the laboratory was responsible for the development of the complex firing tables required to accurately target long-range ballistic weaponry. Hundreds of these tables were required to account for the influence of highly variable atmospheric conditions (air density, temperature, etc.) on the trajectory of shells and bombs. Prior to the arrival of electronic computers, these tables were calculated and compiled by teams of human "computers" working eight-hour shifts, six days a week.

From 1943 onward, essentially all of these computers were women, as were their immediate supervisors. The more senior women (those with college-level mathematical training) were responsible for developing the elaborate "plans of computation" that were carried out by their fellow computers.

In June 1945, six of the best human computers at Aberdeen were hired by the leaders of the top secret "Project X " -- the U.S. Army's code name for the ENIAC project -- to set up the ENIAC machine to produce ballistics tables. Their names were Kathleen McNulty, Frances Bilas, Betty Jean Jennings, Elizabeth Snyder Holberton, Ruth Lichterman and Marlyn Wescoff. Collectively they were known as "the ENIAC girls." Today the "ENIAC girls" are often considered the first computer programmers. In the 1940s, they were simply called coders.

The use of the word coder in this context is significant. At this point in time the concept of a program, or of a programmer, had not yet been introduced into computing. Since electronic computing was then envisioned by the ENIAC developers as "nothing more than an automated form of hand computation," it seemed natural to assume that the primary role of the women of the ENIAC would be to develop the plans of computation that the electronic version of the human computer would follow. In other words, they would code into machine language the higher-level mathematics developed by male scientists and engineers.

Coding implied manual labor, and mechanical translation or rote transcription; coders were obviously low on the intellectual and professional status hierarchy. It was not until later that the now-commonplace title of programmer was widely adopted.

The verb "to program," with its military connotations of "to assemble" or "to organize," suggested a more thoughtful and system-oriented activity. Although by the mid-1950s the word programmer had become the preferred designation, for the next several decades programmers would struggle to distance themselves from the status (and gender) connotations suggested by coder.

The first clear articulation of what a programmer was and should be was provided in the late 1940s by Goldstine and von Neumann in a series of volumes titled "Planning and Coding of Problems for an Electronic Computing Instrument." These volumes, which served as the principal (and perhaps only) textbooks available on the programming process at least until the early 1950s, outlined a clear division of labor in the programming process that seems to have been based on the practices used in programming the ENIAC.

Many folks regard a 19th century English woman, Ada Lovelace, as the first programmer ever. She
worked with Charles Babbage on his never-built proto-computers. The programming language Ada is named after her.

She also has her own day where people are encouraged to blog about the achievements of women in technology which I love! http://findingada.com/

My mother, a '43 Penn graduate talented in math, worked on this project during the war. She was the one responsible (along with a military escort) for bringing the work from Penn to Aberdeen each week.

I wish I could 'like' posts on here, this post definitely deserves one. I'm glad we have the opportunity to raise awareness of women's important contributions to the world we have today.
