Nordmann joined Mercedes-Benz in 1950, initially working in sales. He later became head of the sales department and, in 1968, head of worldwide services. In January 1971 he was appointed president of Mercedes-Benz in North America and Canada, retiring in January 1981. Despite his retirement, he continued to hold a position as company director. During his tenure with Mercedes, Nordmann was an early mentor of Jürgen Schrempp, who later became the chief executive officer of Daimler AG. Under Nordmann's leadership, Mercedes sales in the United States increased from 30,000 cars in 1970 to 43,600 cars in 1972, a 0.4% U.S. market share. To further expand the market presence in North America, Mercedes in 1976 opened a facility in Jacksonville, Florida. In 1977 Daimler bought the Euclid Company of Ohio and Freightliner Trucks in 1981. In 1981 Nordmann attended an aviation symposium of the International Order of Characters (IOC) held in Stamford, Connecticut. The symposium panel was made up of four former World War II fighter pilots. In addition to Nordmann, the panel included the former RAF pilots, Sir Douglas Bader and Robert Stanford Tuck, and the former United States Army Air Forces pilot Robert S. Johnson. He died at his home on 22 July 1982 in Greenwich, Connecticut, USA. Nordmann's wife was named Tina. They had a son, Eric, and a daughter, Corinne. Summary of career Aerial victory claims Nordmann claimed 78 aerial victories, 69 of which on the Eastern Front, achieved in flying over 800 combat missions. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 75 aerial victory claims, plus two further unconfirmed claims. This number includes 1 claim over Poland, 8 on the Western Front, and 66 on the Eastern Front. Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 37432". The Luftwaffe grid map covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about . These sectors were then subdivided into 36 smaller units to give a location area 3x4km in size.
