Paul Wolff (German, 1887–1951) was a pioneering photographer best known for popularizing the use of the Leica 35mm camera in the early 20th century. Trained as a physician, Wolff turned to photography with a technical precision and aesthetic clarity that helped define modern photojournalism and industrial photography in Germany. His work spans cityscapes, factory floors, and daily life, often capturing the rhythm of modernity with sharp composition and quiet observation. A prolific writer and teacher, Wolff also played a key role in shaping public understanding of photography as both art and documentation.
