Peter Rachman, tyrant landlord of 1950s and 60s London. Coined the term “Rachmanism” the process of forcing out existing tenants who were on protected rent levels, then getting loads of new tenants (often immigrants who could find nowhere else) at much higher rents. One set of tenants refused to leave, so he had the roof removed from their flat until they did. Met his match in the infamous Kray gangster family, but bought them off.
