Johan Georg Heinrich Ludwig Tønnies (or Tönnies) (10 May 1825 – 11 December 1903) was an early German-Danish photographer who had a studio in Aalborg, Denmark.
He moved to Denmark in the 1850s where he learnt the art of daguerreotypy from the Berlin photographer C. Fritsche in Aalborg and from Wilhelm Schrøder in Copenhagen.
[1] He opened a photographic studio in Aalborg where he soon specialised in the carte-de-visite technique as it facilitated the production of prints.
His photographs often presented people in their working clothes rather than formally dressed for the occasion.
Like Georg Emil Hansen, Tønnies travelled to the area and photographed many Danish soldiers before they went off to fight.
