William Gaertner and Company
Less a single writer than a historic instrument maker, this name is tied to the practical side of early astronomy. The surviving work reads like a window into how telescopes and precision tools were built, sold, and used in the early 1900s.

Astronomical Instruments and Accessories

About the author
William Gaertner and Company was the Chicago scientific-instrument firm founded by William Gaertner in 1896. The business became known for making astronomical and astrophysical measuring instruments, and its work was closely connected with serious scientific use rather than general trade publishing.
The book most often associated with the name, Astronomical Instruments and Accessories, is essentially a detailed catalog of the company's equipment. That makes it useful not just as a manual for period instruments, but also as a snapshot of the tools and techniques available to astronomers in the early twentieth century.
Because this is a company name rather than an individual author, there does not appear to be a standard personal biography or portrait to use here. What stands out instead is the firm's long reputation for precision craftsmanship and its place in the history of scientific instrument making.
