I've been thinking about fathers and mothers quite a bit lately. Not necessarily the parents
of human children, but those who brought a big idea into the world. Women like Hedy Lamar and Harriett Tubman. Men like Thomas
Stockham and Philo Farnsworth.
First I thought about Thomas
Stockham, the father of digital recording. I heard him lecture here at the
University of Utah in the early 70's as he started to experiment with digital restoration
of Enrico Caruso recordings. Now as I listen to Caruso on CD (or any
CD for that matter), or
edit audio on the desktop, it seems fitting to remember Stockham.
Next Philo Farnsworth came to mind. Probably because of a Doug Fabrizio interview on KUER with Dan Stashower, author of The Boy Genius
and the Mogel, The Untold Story of Television. I also remember the way producer Kirk
Strickland used Farnsworth's medium to portray a young Philo in a public
service announcement for Pioneer, Utah's
Online Library.
To be honest about it, Lamar and Tubman weren't top-of-mind names
to me. I found them browsing Women Inventors online. You could call Hedy
Lamar the mother of spread spectrum cryptography. She titled it A Secret Communications System in her 1942 patent. The impact today? Pagers, cellular
phones, Internet bandwidth and military anti-jamming devices.
About Tubman. Last night at the dinner table I posed this trivia
quiz, "Who
is Harriet Tubman?" To my delight our sixth grader nailed it in about
15 seconds, "Didn't she start the underground railroad?" But course
what Tubman "invented" wasn't at all trivial.
