Over a period of eight years, for example, he produced 600 illustrations for the three-volume Handatlas of Human Anatomy by the physician Werner Spalteholz (1861-1940), published in Leipzig in 1913, which are regarded as masterpieces of anatomical drawing.
In 1913, he was the responsible artistic director of the art volume Das Völkerschlachtdenkmal (Weiheschrift 1813-1913), which contained, among other things, his portraits of the mayors of Leipzig Otto Georgi, Rudolf Dittrich and Carl Bruno Tröndlin [de].
He was also a member of the Leipzig artists' association Leoniden, founded by Edwin Bormann, Georg Bötticher and Arthur von Oettingen, for which he produced numerous graphic works.
[7] Héroux, whose household had been run by his half-sister Aurelie Geyer since his mother's death,[8] was from the beginning of the 1920s with Melitta Winkler,[9] married to a teacher for rhythmic education trained at the Mary Wigman School.
His flat and studio were initially located at Johannisallee 11, and from 1913 he occupied the 4th floor of the Jugendstil apartment building at Scharnhorststraße 2 in Leipzig, which was built according to plans by Georg Wünschmann and artistically decorated by Héroux.
Since his birth, Bruno Héroux has been closely associated with the imperial trade fair city, where he developed his pencil art and thus significantly promoted Leipzig's fame as one of the focal points of graphic work.
With Bruno Héroux, whose collective exhibition in Chemnitz we were able to report on only recently, the Leipzig State Academy for Graphic Arts and Book Trade has also lost one of its best artists.
