S. Lewis (Samuel Lewis) Ziegler

Born in 1861 and active in Philadelphia, S. Lewis Ziegler was an American ophthalmologist best known for his work on diseases and surgery of the eye. Records of his publications and library catalogs show a long list of medical writing, including studies of lacrimal disease, ocular metabolism, corneal tattooing, and his book History of Iridotomy.

Contemporary medical sources describe him as a prolific author and inventor in ophthalmology, especially interested in surgical instruments and the use of electricity in eye treatment. His career was closely tied to major Philadelphia institutions, and his published work identifies him with Wills Eye Hospital and St. Joseph’s Hospital.

Ziegler also wrote beyond narrow specialist practice. The New Philadelphia General Hospital presents him as director of Public Health and Charities, showing his interest in hospital planning and public medical care as well as eye surgery. He died in 1926.
