Bill Gate's Father was Head of Planned Parenthood
In his own words during a Bill Moyers interview, Bill Gates says his father, Bill Gates Sr., was head of Planned Parenthood.
MOYERS: But did you come to reproductive issues as an intellectual, philosophical pursuit? Or was there something that happened? Did come up on… was there a revelation?
GATES: When I was growing up, my parents were almost involved in various volunteer things. My dad was head of Planned Parenthood. And it was very controversial to be involved with that. And so it's fascinating. At the dinner table my parents are very good at sharing the things that they were doing. And almost treating us like adults, talking about that.
My mom was on the United Way group that decides how to allocate the money and looks at all the different charities and makes the very hard decisions about where that pool of funds is going to go. So I always knew there was something about really educating people and giving them choices in terms of family size.
