As liaison officer for the British
Department of Scientific and Industrial Research during the
Second World War, Lord Suffolk and his colleague Major A. V. Golding (1902–1992) were posted to Paris. They, and their private secretaries, Eileen Beryl Morden (Suffolk) and Marguerite Nicolle (Golding), left Paris on 10 June 1940 due to the impending
fall of France. From there they made their way to
Bordeaux, where representatives of the British embassy introduced them to the master of the British tramp ship , which was one of many standing by to carry refugees to safety. They embarked 33 eminent scientists, with their families. Two more scientists,
Lew Kowarski and
Hans von Halban, arrived with the
heavy water. Then the managing director of the
Antwerp Diamond Bank, Paul Timbal, joined, with $10 million worth of gem diamonds. They discovered 600 tons of machine tools in wagons on the quay, which were also loaded. The
Broompark carried them safely to
Falmouth, from where a special train took her passengers and cargo to London. The diamonds were placed in the vaults of the Diamond Corporation and most of the heavy water was sent to
Windsor Castle, where it was stored alongside the
Crown Jewels, until needed. Suffolk's approach to his missions earned him the nickname "Mad Jack" or "Wild Jack".
Herbert Morrison, Minister of Supply, later described him as "one of the most remarkable young men employed by the Government on dangerous missions". Morrison told the House of Commons, when in Secret Session, that "a considerable service has been rendered to the Allied cause by the safe arrival of this shipload".
Bomb disposal career and death Following his return from France, Lord Suffolk worked for the
Ministry of Supply as a research officer learning how to
defuse bombs of new and unknown types. He served as part of an unexploded bomb detachment in London during
the Blitz. The detachment consisted of himself, his secretary Morden, and his chauffeur, Fred Hards. They called themselves "the Holy Trinity" and they became famed for their prowess in detecting and successfully tackling 34 unexploded bombs with "urbane and smiling efficiency". Morden stood by his side taking notes, as Lord Suffolk worked at defusing the bombs. He looked on each bomb as a new challenge — examining it from all angles, listening to it, his fingers exploring the metal shell, and dictating his conclusions and the method he proposed to use in disarming the bomb to Eileen Morden when the time came for her to take shelter. If anything went wrong, then at least others would not make the same mistake. An official report underlined the strain of his work: "On many occasions Lord Suffolk cleared everyone away from the danger area and proceeded to operate alone. Deliberately he exposed himself daily to danger." He was a fatalist saying that "if my name is on a bomb, that's it". The 35th bomb blew up on
Erith Marshes in
Kent on 12 May 1941, killing all three. The bomb, a weapon, was at one of the so-called "bomb cemeteries", on open ground on the marshes. Bombs were transferred here after being temporarily made safe for transport and then destroyed using controlled explosions. The bomb had been dropped some six months earlier, during the previous autumn, and after removal and transfer to the marshes had been at Erith for so long it had been known to the
sappers as "Old Faithful". It contained two
fuzes, a Type (17) and a Type (50); these two types were in short supply to the Bomb Disposal Sections, intact fuzes being required for instructional purposes, and it was to recover the fuzes that Lord Suffolk was dealing with the bomb. The Type (17) was a delayed-action fuze containing a clockwork mechanism, while the Type (50) was an
anti-handling device containing a motion sensor. The Germans had added a
Zus 40 booby trap to some bombs, that detonated when the Type (17) was withdrawn. The
Zus 40 was below the other fuze and so was not visible until the obvious fuze was partially withdrawn from its pocket. At lunchtime on 12 May, Lord Suffolk had telephoned his office to say that the Type (17) was ticking and that he had sent for an Mk II KIM clock-stopper. By 14:45 this was in place along with a
stethoscope and preparations were being made to sterilise the bomb with steam. As two sappers were going to fetch water for the steamer, the bomb exploded. The explosion killed 14 people: Suffolk, Hards, Morden (who died in the ambulance) and eleven other people who had been nearby, including five sappers who had been working with Suffolk on the bomb. It was later surmised that a
Zus 40 may have been triggered as Lord Suffolk was removing it. ==Personal life==
