German author and artist Fritz Kahn made this poster in 1926 depicting the human body as an ‘industrial palace’ by turning it into a complicated chemical plant using metaphors of 1920’s industrial life.
I find Kahn’s almost morbid ‘dream’ anatomy very interesting. His mechanical visualization of the inner workings of the human body reminds me of a somewhat similar illustration I loved to look at when I was in the fourth grade.
I stumbled across a ‘mechanical inner man’ illustration in an old three-volume encyclopedia in the school library. It was less complicated than the Kahn poster (pictured) but as a fourth grader I was intrigued by it and often drew my own versions (wish I’d kept those drawings).
