Dame Stella Rimington was born in South London to a working class family in 1935. After working as an archivist for several years she was first recruited into MI5 in 1967 while in India where her husband was working for the British High Commission. Over the decades she rose through the ranks, serving in all three of the main branches of MI5: counter-subversion, counter-espionage and counter-terrorism. She was head of MI5’s counter-terrorism branch at the time of the Patrick Finucane assassination. Dame Stella eventually became Director General in 1992, serving in that post until 1996.
