He was the son of tailor's Johann Friedrich Heuer and Christina Magdalena, née Lehmann from Uelzen.
In the same year, Heuer began a long-lasting collaboration with a glorious lithographic institution in Hamburg, the firm of Charles Fuchs.
It was there that Heuer's first major work appeared in August 1842, a panorama of the burnt Hanseatic City Hamburg, which cost 12 marks in coloured form.
[2] Afterwards, Heuer worked, among others, for the Berendsohn'sche Kunst- und Buchhandlung, for which he produced a series of "historical situation and topography pictures from the [...] history of Hamburg".
He lithographed drawings and also photographs that the explorers had brought back to Hamburg from the South Seas for the Museum Godeffroy.
