Dale Hileman is an erstwhile inventor and writer at 81.
Hileman and his family moved around and finally wound up in Chicago when he was 10. He eventually enrolled at the University of Illinois in engineering.
“But math was boring and I was lazy so I switched curricula to get a B.S.J. (Journalism), much easier,” he said. “Then I went to work as a tech writer, starting at an Iowa electronics firm, later transferring to the California branch, discovering the wondrous Mojave Desert, becoming an avid rockhound.”
