The innovative television drama Cathy Come Home caused shock when it was aired on BBC One in 1966.
He told the heartbreaking story of a young fictional family expelled from his home, putting the disadvantage and lack of housing on public awareness and on the political agenda in a new way.
The drama, directed by Ken Loach, was produced by Tony Garnett, who died Sunday. But the legacy of Cathy Come Homes continues, more than five decades later.
The homeless charity Shelter was, by coincidence, launched a few days after its issuance. Both he and Crisis, founded shortly thereafter, attribute to the program the creation of a wave of support that helped establish their initial work.
