Friedrich Uhlhorn

In collaboration with Edmund Ernst Stengel, he published the Geschichtlichen Atlas von Hessen, which is considered his major work.

[6] His connection to his doctoral supervisor Edmund E. Stengel and the "Atlaswerkstatt", the later Hessisches Landesamt für geschichtliche Landeskunde [de] with its seat in the Kugelhaus in Marburg, also continued during his work as archivist.

From 1935, Uhlhorn was responsible for Edmund Stengel's new project, and he was also in charge of the preparation of the Geschichtliche Hand- und Volksatlas von Hessen.

[4] After the end of the war, Uhlhorn pursued the goal of providing a first delivery of atlas maps for the entire area.

[6] Even after his retirement, Uhlhorn continued to work on this atlas and its design and layout,[2] From 1960 to 1978, twelve volumes were published, comprising a total of 79 maps and 53 sheets.

[2] His collaboration on the Geschichtlichen Atlas von Hessen, which is his main work, his function as chairman of the Marburg Historical Society,[3] but not least his numerous publications on Hessian state history topics clearly show his deep connection to Hessian history and his interest in research until his death in 1978.

In his obituary of him, Fred Schwind emphasizes that during his time as archivist of the Princely House of Solms, he sought to convey to his students the "insight into the intimate relationship between the landscape and the historically active man [...] in his lectures and especially on excursions.

"[2] From 1951 on, he was responsible as editor for the first 14 volumes of the Hessian Hessischen Jahrbuchs für Landesgeschichte[15] and is thus also significantly involved in its presentation and the high standing it occupies among the journals of the State history.
