The Man of the Family - Bennett, Robert Wallace

A boy's military father eventually abandons the family, leaving the author as a child to grow up supporting his family with a dizzying array of jobs while putting himself through school, in the process becoming perhaps one of the most important experts on rabbits in the world. Bennett also serves in the military and sees action during the Korean War. He manages to earn multiple degrees and work for some of the largest companies in the world, all while supporting his family. It is almost as if Bennett never slept. His advice on rabbits is sought after by people around the world, and his many books on the subject have sold in the thousands in dozens of countries.
