I wouldn¹t lay claim to the mantle of ³great engineer,² but I have had a very successful and fulfilling career, and greatly exceeded my expectations going into the field.
While the names of my mentors might not mean much to most of you, it is the specific knowledge and skills I was able to access from each that is important. >From Bill Briles, who worked in aerospace and military aviation, I learned empiricism, in a sense. That is, to learn a lot of the facts and sources and to be able to quote chapter and verse on any topic of interest. He was a master of quoting any relevant military standard on just about any electrical engineering topic. >From H. David Fassburg, a radar systems and EMC engineer, I learned to think about things and analyze them, not merely quote chapter and verse from some authority. Both empirical knowledge and analytical skills are necessary. And finally, from Mark Nave, five years my junior, I learned to look at EMC engineering not only as a technical skill, but as a profession. Mark Nave ignited the desire to be in business for myself, and imparted some of the skills and knowledge to do so (in addition to teaching me a great deal of EMC design principles). It also helped that at the same time Mark Nave was providing a good Force, there was a dark Force propelling me out the door of my employer. I owe as much to a particularly unpleasant boss in this regard. But I had had such in the past with no such response or even consideration on my part, so it took both the bad Force of a bad boss and the good Force to push me successfully in the right direction.

I was lucky to have been mentored by Michael King when I was younger. He is a great scientist/engineer and had a great effect on me. I was fortunate to have four great mentors in my life: my Father, George Florio (who got me into this field at age ten and helped me to become an engineer by age 14), Henry Ott, and Michael King. I can¹t imagine my life without these great men. Maybe others can post about mentors who helped them become engineers.
