Stephen Henry Horgan (February 2, 1854 – August 30, 1941), was the inventor of the halftone process for newspaper usage, and early-on improvements.
Stephen Henry Horgan was born in Norfolk, Virginia on February 2, 1854.
[1][2] The half-tone method he invented was to use a glass screen with fine lines in it which translated the gradations of an image when placed between a light-sensitive metal plate and a negative.
The final image created was a metal picture made of black dots surrounded by white.
[3] It is said that he was fired from that job by Herald publisher James Gordon Bennett, Jr., who described the idea as idiotic.
