Tracking the story of the ENIAC programmers

Six women who changed computing finally get their day in the spotlight.

More than 70 years ago, six brilliant mathematicians came to Philadelphia to take part in a secret U.S. Army project designed to help the Allies win World War II. These young pioneers of the computing age learned to program using only logical diagrams and their considerable talents—no programming languages or tools existed to help them.

The result of their efforts was ENIAC (Electronic Numerical Integrator And Computer), the first all-electronic programmable computer, capable of running a ballistics trajectory—a differential calculus equation—in seconds.  The Army unveiled ENIAC to the public in 1946, but the six mathematicians who poured their brainpower and creativity into the project were never recognized for their work.

They were the first modern-day programmers, but they were also women and expected to stay in the background. In photos from the ENIAC public debut, they are pictured but not identified, functioning as “refrigerator models” as one computer historian termed it, a reference to 1950s TV commercials for home appliances, in which smiling female models in high heels would open refrigerator doors.

learned about the ENIAC project as a student and has devoted much of the last 20 years to telling the story of the ENIAC programmers and to ensuring they receive credit for their pivotal role in computing history. Kleiman launched the ENIAC Programmers Project, and in 2008 she talked about her efforts at an event sponsored by RENCI and Duke University.

This February, she was back at Duke, introducing the documentary The Computers, the award-winning film she spearheaded that premiered at the 2014 Seattle International Film Festival. The film explains the daunting tasks the ENIAC team faced and delves into the backgrounds of the women of ENIAC: Kathleen Mauchly Antonelli, Frances Bilas Spence, Frances “Betty” Snyder Holberton, Jean Jennings Bartik, Marlyn Wescoff Meltzer, and Ruth Lichterman Teitelbaum. Over the years, Kleiman interviewed and became close friends with four of the women (Antonelli, Bartik, Holberman, and Meltzer). Their frank comments and remembrances are sprinkled throughout the film and help recreate a time when sexism was temporarily put on hold in order to win the war.

While most women who were recruited into the job market in the early 1940s were pressured to leave the workforce after the war, the ENIAC programmers stayed on in the nascent field of computer programming because, as Kleiman said, “no one else knew how to program the ENIAC.”

Kleinman believes telling the story of the ENIAC women and influential female computer scientists can change stereotyped beliefs about professional occupations, inspire more girls to pursue IT careers, and ultimately lead to an IT community that is more inclusive and successful at developing products that serve a diverse population.

“As my mother used to say ‘If we don’t know our history, we are doomed to repeat it,’” said Kleiman. “And we don’t know our history. We don’t know about these women pioneers. And it might make a difference if we do.”

The Computers was written and produced by Jon Palfreman, Kathy Kleiman, and Kate McMahon, with major funding from the Brin Wojcicki Foundation and the Donor Advised Fund on behalf of Lucy Southworth Page. For a full list of funders, click here.

RENCI scientist set to join the ranks of Climate Reality Leaders

As the Climate Reality Project website says: Ordinary people face challenges. Climate Reality Leaders embrace them.

RENCI’s Chris Lenhardt, an environmental data science and systems expert, will join the ranks of these leaders when he attends three days of training Oct. 17 – 19 to become part of the Climate Reality Leadership Corps. The Leadership Corps is a global network of individuals committed to tackling the climate crisis and solving what is far and away the greatest challenge of our time. The Leadership Corps is part of the Climate Reality Project launched by former Vice President Al Gore to increase awareness about climate change and to support efforts at all levels aimed at reducing carbon emissions.

Data Fellows project aims to make storm surge predictions faster and more accurate

By Nelson Tull

Note: Nelson Tull is a graduate student in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. His faculty advisor, Casey Dietrich, is an NCDS Data Fellow conducting research to improve hurricane and storm surge guidance to emergency managers in North Carolina’s coastal counties. Dietrich’s Data Fellows research builds on previous work supported by the North Carolina Sea Grant program. Other collaborators are Rick Luettich, head of the Institute of Marine Sciences at UNC-Chapel Hill, Brian Blanton, a senior research scientist and oceanographer at RENCI, and Jason Fleming of Seahorse Coastal Consulting. To learn more about this research, tune into the September 2017 NCDS DataBytes webinar.

When lives are on the line, minutes count but so does accuracy
Storm surge model forecasts are a critical tool used by coastal emergency managers to plan and make decisions. These models must be both accurate and fast to give reliable information in a timely manner as a storm moves toward the coast. The forecast guidance must also be visualized in a way that is meaningful to those who need this vital information. Read more…

NSF-funded undergraduate researchers get a taste of life at RENCI

A panel of RENCI employees talks to NSF REU students during a recent visit.

On July 21, RENCI hosted 11 students and two professors from the National Science Foundation’s Research Experience for Undergraduates (REU) program. The program allows undergraduates to actively participate in research in any of the areas of research funded by the NSF. REU projects involve students in meaningful ways in ongoing research programs or in research projects specifically designed for the REU program. As a part of their REU experience at North Carolina A & T State University, a group of undergraduate students from diverse backgrounds and several universities came to RENCI for an educational tour.  Read more…
