Dad had an interesting career. Started as an office clerk for a railway with only high school education. Then he got into using an IBM 650 (IIRC) for doing freight rate calculations. How he managed that transition, I have no idea. He didn't care for being cooped up all day flipping switches, dealing with punch cards and tapes.
He switched to marketing and got on there very well and retired after 37 years as a regional director.
He always has a book on the go, even now at 83. He has an eclectic pile of them that he kept, from Zane Grey to an early history of the Civil War written around 1870.
