Grundlagen der Elekrotechnik
A German-language introduction to the fundamentals of electrical engineering written by Rudolf Blochmann and published by B.G. Teubner in Leipzig in 1907 for students and technical apprentices. The plates are spare pen-and-ink diagrams: hatched pole pieces marked S and N, arrowed field lines, wound armatures and coils, commutators, dial meters and filament lamps, usable as ready-made schematic motifs, hatching textures and arrow conventions.
