"Giorgio Sommer (1834–1914) was born in Frankfurt am Main (in modern-day Germany), and became one of Europe’s most important and prolific photographers of the 19th century. Active from 1857 to 1888, he produced thousands of images of archeological ruins, landscapes, art objects and portraits.
After studying business in Frankfurt, Sommer opened his first photography studio in Switzerland, where he made relief images of mountains for the Swiss government. In 1856 moved his business to Naples and later (1866) formed a partnership with fellow German photographer Edmund Behles (also known as Edmondo Behles) who owned a studio in Rome. Operating from their respective Naples and Rome studios, Sommer and Behles became one of the largest and most prolific photography concerns in Italy." - (en.wikipedia.org 18.11.2019)
