500 other soldiers he was transferred to the Pioneer Corps and later to the North Staffordshire Regiment in 1943. He was then involved in action across Europe, from the Normandy beaches to Berlin, and achieved the rank of sergeant. Maxwell gained a commission in 1945 and was promoted to the rank of captain. In January 1945, Maxwell's heroism in "storming a German machine-gun nest" during the war won him the Military Cross, presented by Field Marshal Bernard Montgomery. Attached to the Foreign Office, he served in Berlin during the next two years in the press section. Maxwell naturalised as a British subject on 19 June 1946 and changed his name by deed of change of name on 30 June 1948. In 1945, Maxwell married Elisabeth "Betty" Meynard, a French Protestant, and the couple had nine children over the next 16 years: Michael, Philip, Ann, Christine, Isabel, Karine, Ian, Kevin and Ghislaine. In a 1995 interview, Elisabeth talked of how they were recreating his childhood family who were killed in the Holocaust. Five of his children – Christine, Isabel, Ian, Kevin and Ghislaine – were later employed within his companies. His daughter Karine died of leukaemia at age three, while Michael was severely injured in a car crash in 1961, at the age of 15, when his driver fell asleep at the wheel and crashed headlong into another vehicle. Michael never regained consciousness and died seven years later. After the war, Maxwell used contacts in the Allied occupation authorities to go into business, becoming the British and US distributor for Springer Verlag, a publisher of scientific books. In 1951, he bought three-quarters of Butterworth-Springer, a minor publisher; the remaining quarter was held by the experienced scientific editor Paul Rosbaud. They changed the name of the company to Pergamon Press and rapidly built it into a major publishing house. In 1964, representing the Labour Party, Maxwell was elected as Member of Parliament (MP) for Buckingham and re-elected in 1966. He gave an interview to The Times in 1968, in which he said the House of Commons provided him with a problem. "I can't get on with men", he commented. "I tried having male assistants at first. But it didn't work. They tend to be too independent. Men like to have individuality. Women can become an extension of the boss." Maxwell lost his seat in 1970 to Conservative challenger William Benyon. He contested
