Hübler, K. Collection of two albums containing a total of 21 original technical construction drawings, mostly double-lined. 1891–1893. Pen and watercolor on sturdy paper. Folio, contemporary cloth binding (heavily rubbed and stained). Karl Hübler was appointed government architect at the Water and Road Construction Administration in Mannheim in 1898. In 1921, he was awarded an honorary doctorate from the School of Engineering at the Technical University in Karlsruhe “in recognition of his outstanding achievements in the fields of civil engineering, tunnel construction, and hydraulic engineering.” (See *Deutsche Bauzeitung*, Vol. LV, p. 430) Hübler also served as director of the Mannheim-based construction firm Grün und Bilfinger. - The first volume, containing 10 designs—most of which are double-sheet in size—includes, in particular, construction drawings for steel railway and road bridges, featuring floor plans, cross-sections, structural diagrams, and railroad switches. Among them is a large-format drawing on three sheets depicting the design of a junction station. The second volume, containing 11 drawings, deals with the design of a dam and a river correction project and includes depictions of weirs, locks, longitudinal profiles, etc. - The drawings mostly include scales and inscriptions; most are signed and dated. - Some are slightly stained; one drawing is more heavily stained. Slightly yellowed due to the paper. Overall, a very well-preserved and historically interesting collection.
