About the author
Born in 1861 and active in Philadelphia, Samuel Lewis Ziegler was a physician who specialized in diseases and surgery of the eye. Records from library and archival sources identify him as both a medical author and a public-health figure, and his surviving publications show a strong focus on ophthalmology.
Ziegler wrote technical works including History of Iridotomy and The New Philadelphia General Hospital. His ophthalmic writing reflects a surgeon deeply interested in methods, instruments, and the history of eye operations, especially procedures involving the iris. That makes his work useful not just as medical instruction, but also as a window into how specialists explained and refined surgical practice in the late nineteenth and early twentieth centuries.
He died in 1926. Although he is not widely known outside medical-history circles today, his books continue to be preserved by archives, libraries, and digitization projects, which suggests a lasting interest in his contributions to early ophthalmology and hospital medicine.
