He received a loan from Allen & Unwin, the London publishing house, which represented Baedeker in Britain, and continued to do whatever he could to rejuvenate the firm at home. On July 1, 1927, Hans celebrated the centenary of its foundation by holding a reception at the Leipzig "Harmonie", a popular venue for such events. The firm did make some progress and he managed to produce twelve new titles in German and five in English, though these included those commissioned by the Nazi regime. He also published the 1928 one-volume eighth and revised German edition of "Egypt" and in 1929 its eighth English edition, which many travel guidebooks connoisseurs and collectors consider to be the two finest Baedeker travel guides ever published.
