Richard Hegemann was born in 1880 in Erfurt. He studied in Berlin and Paris and worked in Berlin. He would use pseudonyms such as A. Hegener and P. Rollmann, or sign with just the initials R.H.) and did many spanking art and fetish drawings in the 1920s, a number of which were published later as illustrations in reputable German publications of Sexual Research Institutes in the early 1930s. Such as Ernst Schertel’s “Der Flagellantismus als literarisches Motiv” (1929-1932)
Richard Hegemann was probably a female artist from Berlin who created these drawings for her own pleasure and as gifts or commissions for like-minded friends. In addition to (mostly pencil) drawings, she also did some colored works in watercolor. Richard Hegemann's art shows scenes of dominant women (mainly F/F, F/m and F/M). Boys in Hegemann's art typically wear a sailor suit. In Germany of the 1920s, spanking fetishism was considered a serious sexuality disorder that needed therapy, so the artist ended up in psychotherapy in the late 1920s.
The pyschologist he was seeing talked him into entrusting him with any drawings she still had. She also persuaded some of her spanking art friends to do the same, so the therapist soon had an impressive collection of original spanking art. (A very similar story happened to Helga Bode.)
Besides spanking art, Richard Hegemann would also draw enema art and what appears to be male cross-dressing.
