Sharla Boehm, a math teacher moonlighting at RAND, built the simulation that proved packet switching could survive a nuclear attack, foundational to the Internet.
Key Takeaways
Boehm wrote the simulation for Paul Baran’s distributed network concept at RAND in the early 1960s, demonstrating that message packets could route around failed nodes.
Her work addressed a real failure: a single overheated relay motor in Colorado in 1961 nearly triggered accidental nuclear war by knocking out all SAC communications.
Baran’s distributed packet-switching idea faced rejection from AT&T engineers and analog-communications colleagues; Boehm’s simulation was the concrete proof they needed.
She co-authored a major RAND paper with Baran but was omitted from standard Internet origin histories, including Katie Hafner’s 1996 book “Where Wizards Stay Up Late.”
Boehm taught math at Santa Monica High School and coded summers and sabbaticals at RAND, one of very few women in engineering roles at the time.
Hacker News Comment Review
Commenters confirm Boehm’s specific technical contribution: she wrote the first working implementation of packet switching, also called “hot potato routing,” proving the concept viable.
No substantive technical debate in comments; the thread functions as a quick-ID reference with a Wikipedia pointer for deeper background.
