Carl Peter Mazér (9 March 1807, Stockholm – 27 July 1884, Naples) was a Swedish painter, graphic artist, and photographer.
At an early age, he became interested in painting, and was able to study with Gustaf Erik Hasselgren at the Royal Swedish Academy of Fine Arts.
In 1825, he accompanied his father to Paris and took lessons from Antoine-Jean Gros; becoming his assistant and helping to paint the backgrounds on historical scenes.
He would eventually spend fifteen years in Russia; living in Moscow and Yaroslavl, where he worked as a drawing teacher.
After returning to Stockholm in 1854, he had difficulty making a living from his art, and became exclusively involved with photography; creating a professional manual in 1864.
