Retired project engineer. Worked for a machine development and manufacturing company for 32 years. No degree, just practical know how! The owner and founder of the company was from Germany and came over to the U.S. during world war II. No degree, just practical know how! He was the best machine development person I ever knew. The business sold machines around the world as well as in the United States and still does. Our products helped our customers out-perform all of their competition. I did mostly the electrical systems and some pneumatics but I also did some mechanical design and fabrication.
