author
b. 1851
Best known for a practical late-19th-century guide to photo-lithography, this Vienna-based technical writer wrote from the shop floor rather than from theory alone. His work gives a clear window into how photography and printing were coming together in the industrial age.

by Georg Fritz
Georg Fritz was a German-language technical author active in the late 19th and early 20th centuries. The clearest detail I could confirm is his authorship of Photo-Lithography (1895), a hands-on manual that presents him as vice-director of the Court and Imperial State Printing Works in Vienna.
In the book's preface, he describes the subject as a working practitioner would, emphasizing tested methods and practical usefulness over long historical discussion. That makes his writing especially approachable for readers interested in the craft side of early photographic printing.
I could not confidently verify more personal biographical details from reliable open sources in this search, so this overview stays focused on the part of his life that is clearly documented through his published work.
