district government and was to be produced alongside the primary academic atlas Geschichtlicher Atlas für Hessen und Nassau. Stengel named the Hessian people and the Hessian youth as a target group in order to bring the Hessian landscape closer to them again. By the beginning of the Second World War, however, it was no more than a draft. After the Second World War, in which he participated just as in the First World War, he became curator at the Hessian State Office for Historical Regional Studies in 1947. After the end of the war, Uhlhorn pursued the goal of providing a first delivery of atlas maps for the entire area. Thus he prepared political maps for the years 1550, 1648 and 1789, which were never published. The project was later discontinued despite Uhlhorn's intensive efforts. Uhlhorn also started work on the Geschichtlichen Handatlas during this period. Following on from the work before the outbreak of war, this atlas was intended to serve schools, universities and all those interested in history as a reference and illustrative work. Uhlhorn worked intensively on this project, various government agencies were interested in the creation of this map series, which ultimately convinced Stengel, who was not too keen, of the necessity of this project and put the completion of the "großen Atlas" first. This project was not completed in addition to the many other projects. However, a number of smaller scientific atlases were published, one of the first in Germany being the Geschichtlicher Atlas von Hessen. From the winter semester of 1964 he was granted a leave of absence for health reasons. Even after his retirement, Uhlhorn continued to work on this atlas and its design and layout, From 1960 to 1978, twelve volumes were published, comprising a total of 79 maps and 53 sheets. The volume with text and explanations published by Fred Schwind in 1984 concluded the atlas. Uhlhorn died in Marburg on July 24, 1978 at the age of 84 and was buried at the cemetery at Rotenberg in Marburg. The city of Marburg declared his grave a municipal grave of honour. Achievements Uhlhorn's achievements in the scientific field of Hesse's state history are particularly noteworthy. He was well known beyond the borders of Hesse, for example, as he dealt with the historical foundations of the present-day state of Hesse at an early stage.
