Looking for a book I read when I was 10.

When I was young, a book that made an impression on me was about a man who had many children, so he created instructions on how to do their every day tasks in the most efficient way possible. He was basically the inventory of Process Improvement in my mind.

I have forgotten the title of the book but have been searching for it off and on for decades. I would have read it in the 70’s or early 80’s. Anyone here have ideas on what the title might have been?
