Gerard Steenson (1957 - 14 March 1987) was an Irish republican socialist paramilitary activist. He was a member of the Irish National Liberation Army (INLA) group during the Troubles in Northern Ireland.
He was born in Belfast, Northern Ireland, and grew up in a Roman Catholic family in the republican Falls Road area of west Belfast.
Nicknamed "Doctor Death" by sections of the Irish media, he is widely associated with internecine violence between Irish republican groups. He joined the Official IRA's C Company in 1972 at the age of 14. Two years later, he left to join the INLA upon the paramilitary group's formation consequent to their split from the Official IRA. He came to notoriety as a 16 year-old for killing Billy McMillen the Official IRA's Belfast leader during the IRSP/INLA's feud with the rival Official IRA. He had been dubbed "Dr. Death" by the RUC for the chain of assassinations he purportedly accomplished.[1]
Steenson, Jimmy Brown and others formed the Irish People's Liberation Organisation with the express intention of wiping out the INLA and IRSP which they had seen as becoming corrupt and an obstacle to the fight for socialism and Irish freedom. Steenson argued in letters written while he was in prison in the early 1980s that the INLA had become militarily inefficient and undisciplined and that this had led to involvement in criminality and sectarian attacks.
In 1987, Steenson himself was killed with his friend Tony McCarthy by the INLA. Two revenge killings of INLA men followed before the end of the feud.
