author
An early writer on optical projection and X-ray work, he helped document practical techniques at a moment when new visual technologies were rapidly changing science and public demonstration. His surviving books point to a career rooted in hands-on explanation rather than literary celebrity.

by Lewis Wright, Russell Stuart Wright
Russell Stuart Wright was a British engineer and technical writer, born in 1876, who is associated with early work in optics and X-ray technology. Grace's Guide identifies him as the son of Lewis and Eliza Wright, notes that he was educated at Tollington Park College and King's College London, and describes him as having worked first in optics before specializing in X-rays.
He is best remembered in the book record as the co-author, with Lewis Wright, of Optical Projection. Part 1: The Projection of Lantern Slides. Listings from Project Gutenberg and library-book databases confirm that this practical work on projection and lantern use has remained the main title linked to his name.
Reliable portrait evidence was not available from the sources I could confirm, so no profile image is included here. Overall, the picture that emerges is of a technically skilled specialist who wrote for readers interested in scientific demonstration and visual technology.
