My father probably qualifies too. In the early 80's we had a Bell Labs/Western Electric Energy management system with home sensors and links to the electric and gas companies. They used a Z80 microprocessor in a STD bus card rack. And at no point in the last 30+ years has he ever been without projects or machines to work on.

His skillset goes from the EPROM and PLC level, through C/C++, and on to actual 20 ton open die forging. I've seen him take a break from debugging a C++ driver for a hydraulic beam loader to replace live high voltage fuses with a hot stick rather than wait for the power company. It really puts what we refer to as 'full-stack' into perspective.
