When Judith Love Cohen was nineteen, a guidance counselor at her high school gave her a simple piece of advice:
“Nice girls go to finishing school.”
Judith enrolled in engineering instead.
At Brooklyn College, she sat in lecture halls where she was often the only woman. Whenever she raised her hand to answer a question, the boys laughed.
So she raised it higher.
She later transferred to USC, earning both her bachelor’s and master’s degrees in engineering. Out of 800 graduates in her class, only eight were women. At the time, women made up less than half a percent of America’s engineering workforce.
But Judith did not stop there.
She joined TRW, a NASA contractor, where she worked on one of the most critical systems of the Apollo program: the Abort Guidance System for the Lunar Module.
This was not an ordinary backup computer.
It was the emergency system designed for the worst possible moment. If the primary guidance failed in space, this system was the astronauts’ last chance to get home alive.
“It had to work,” Judith later said, “because if you needed it, you were already dying.”
By 1969, she was nine months pregnant and still working full-time on final calculations. Her coworkers urged her to go home and rest.
The equations were not finished.
So neither was she.
One morning in August, contractions began. Judith gathered stacks of printouts filled with trajectories, circuitry diagrams, and calculations, then headed to work anyway.
When the pain intensified, she finally agreed to go to the hospital.
She brought the printouts with her.
In her hospital bed, between contractions, she suddenly spotted the final flaw in the guidance system.
A nurse walked in and found her scribbling equations.
“Ma’am,” the nurse said, “you’re in labor.”
“I’m in math,” Judith replied.
She solved the problem.
Then she gave birth to a baby boy: Thomas Jacob Black.
The world would later know him as Jack Black.
The next morning, Judith called her boss from the hospital.
“I fixed the guidance problem,” she said calmly.
Then she added:
“Oh, and the baby came too.”
Eight months later, Apollo 13 exploded.
More than 200,000 miles from Earth, an oxygen tank failure crippled the spacecraft. The astronauts climbed into the lunar module with almost no margin for survival.
Then Judith’s system activated.
Her Abort Guidance System calculated critical engine burns, stabilized navigation, and helped guide Apollo 13 safely back to Earth.
Astronaut Jim Lovell later acknowledged the importance of the system:
“Without the AGS, we don’t come home.”
Judith never stopped building after that.
She worked on satellites, space systems, and programs that helped open doors for future generations of women engineers. She also wrote children’s books encouraging girls to pursue science and engineering careers.
“Girls need to see it to be it,” she said.
Years earlier, a counselor had suggested finishing school.
Judith Love Cohen chose equations instead.
And from a hospital bed, between contractions, she helped bring three astronauts home from space.
She proved that “nice girls” were never the limitation.
The world’s expectations were.
