He designed and built steam locomotives for the Pennsylvania Railroad back in the good old days.My grandfather was also an electrical engineer and a mechanical engineer.
He was naturally gifted and smart, plus he never quit trying or gave up on a project. He was incredibly persistent and resolute. Once he set his mind on something, he went for it, no matter what the cost.I think the main ingredients of his success were intelligence and tenacity.
