Peter Ludvig Rudolph Striegler (4 October 1816 – 24 January 1876) was one of Denmark's early photographers, specialising in portrait photography.
Trained as a picture-framer, Strieger opened Odense's first daguerreotype studio in 1846.
[2] The idea of using a photograph instead of a printed visiting card came from France where it was patented by André Adolphe Eugène Disdéri in 1854 with a four-lensed camera which could take from eight to twelve photographs on the same glass negative.
[4] He was also one of the early photographers who took portraits of Hans Christian Andersen.
In his diary entry for 22 October 1861, Andersen writes: "Stood for Siegler until 11.30 and had a few large and small pictures taken of me.
