Snapper Foster was the son of Bill and Liz Foster. He had one younger brother, Greg, and one younger sister, Jill. Born William Jr., Snapper resented being named after his father who had walked out on the family, so he was called “Snapper” after his not-so-winning personality instead. Snapper not only put himself through medical school with a part-time job, but also, as the man of the family, contributed to Greg Foster’s law school tuition and kept a eye on little sister Jill Foster.
