Whilst Chief Engineer at the Atomic Weapons Research Establishment (AWRE), Aldermaston, John Dolphin worked on the Red Beard trigger mechanism. Subsequently, in July 1959, Dolphin requested an ex-gratia financial award for his work on the weapon; but was turned down. His claim was that although it was not his job to do so, he invented the 'Rotary Hot Line' device that eventually became the trigger for the Red Beard bomb (and which was used in all subsequent thermonuclear bombs). He further stated that his invention brought to an end the deadlock in meeting the specification for the Red Beard, and that he had to overcome "serious opposition" against the senior scientists whose job did include the brief for its invention. His claim was refused on the grounds that as a 'Chief Engineer', it was within the scope of his duties.
