contemporaneous titles. Allen & Unwin, the London publisher, once again helped the Baedeker firm with another loan and he published more city and regional guides in the years that followed. In 1951, Karl Friedrich and Oskar Steinheil, a pre-war Baedeker editor, signed an agreement with Shell AG, the subsidiary of Royal Dutch Shell, and Kurt Mair (1902–1957), the German printer and publisher based in Stuttgart, to produce a series of motoring guides. Baedeker would provide the text and Mair the finished product. The Baedekers Autoführer-Verlag, Stuttgart was born. The slim guides called Baedekers Shell-Autoführer (Baedekers Shell Guides) were designed to fit into a man's jacket pocket or in the glove compartment of a car. The first ones covered Germany and were a huge success. Guides on other European countries followed in both German and English. Karl Friedrich was now operating on two fronts. He continued to produce city and regional guides from Malente and with the publication of his 1954 Berlin guide in German, English and French, the Baedeker brand had been well and truly re-established. Florian, his only son, was by his side and his cousin Hans, the son of his uncle Dietrich, was engaged in producing the motoring guides from Stuttgart. Dietrich's other son Otto also helped run the firm until 1971 when he left to join another publishing house. In 1956, Karl Friedrich moved his field of operations from Malente to Freiburg im Breisgau. In 1972, the Stuttgart operation moved to Ostfildern/Kemnat in the district of Esslingen where Volkmar Mair, the son of Kurt Mair, was now in charge. With the rise of air travel in the 1960s and 1970s, Baedeker entered a new era. In 1974, the first post-war international guidebook appeared, financed largely by the German airline Lufthansa—the voluminous 872-page Baedekers USA in German, which had the look of traditional pre-war Baedekers. Florian Baedeker Florian Baedeker (1943−1980), the only son of Karl Friedrich Baedeker, succeeded him when he died in 1979. After completing his studies in Munich in 1971, he had devoted himself to matters relating to book publishing under the guidance of his father, and had helped him with the preparation of the Munich guide, released for the 1972 Munich Olympic Games. Florian also carried out most of the work involved in preparing the city guides titled Baden-Baden, Constance, Strasbourg and Wiesbaden, published in the mid-1970s. He also produced several short city guides. Basel,
