Born in Switzerland, Hans Mauli was a graphic designer who worked with Herb Lubalin and designed the typeface for the World Trade Center signage. From 1971 to 1991 he worked as an advertising photographer in Paris, after which he moved to the United States and began to focus on fine art photography. When he began his photographic career he did not have access to a darkroom, so most of his early work was not printed until much later. See more of them here.
