Connections and all in the family

I was reading about the dead of Aaron Director, founder of Law and Economics, that is the use of economic thinking tools in Law. This last paragraph caught my attention:

He stayed at Chicago for several years as an instructor, also bringing his younger sister Rose to the University. There, she finished her undergraduate work and entered graduate school in economics, where she would meet her future husband, Milton Friedman.

It turns out that Aaron Director was also one of the great promoters of Hayek's Road to Serfdom and even convinced the editors at Chicago University Press to publish it. He also was the teacher of Supreme Court Justice candidate and legal schoolar Robert Bork.


What an influence a man can have into a movement (both through family and ideas).
