Jack Black’s mother is engineer Judith Love Cohen, who helped create the system that rescued the Apollo 13 crew.

When it was time to go to the hospital, she took with her a computer printout of the problem she was working on. Later that day, she called her boss and told him that she had solved the problem. And…oh, yes, the baby was born, too.”
