"Bertha Wehnert-Beckmann (1815–1901) was a German photographer. She appears to have been Germany´s first professional female photographer, and was possibly also the first professional female photographer in the world, being active a few years prior to Brita Sofia Hesselius and Geneviève Élisabeth Disdéri. Together with her husband, she opened a studio in Leipzig in 1843 and ran the business herself from his death in 1847." - (en.wikipedia.org 21.10.2020)
