On St. Patrick’s Day, a holiday significant to engineers in the USA, I wrote about the prominence of that profession within my family. It so happens that I’ve had occasion to expand upon that on another holiday. I’ve never really been big on Father’s Day, despite having four children of my own, but on the usual phone call to my father we got to talking about his background in electron microscopy. ┬áHe was not only a pioneer applying it to materials engineering, but also involved in education, looking to produce the next generation in his field, particularly from Nigeria.
