S. Lewis (Samuel Lewis) Ziegler

Born in 1861 and active in Philadelphia, S. Lewis Ziegler was an American ophthalmologist and medical author. Records of his publications identify him as Samuel Lewis Ziegler, and one of his books, The New Philadelphia General Hospital, describes him as director of Public Health and Charities.

Ziegler wrote on both medical practice and medical history. He is associated with History of Iridotomy, a work on the development of an important eye operation, and with writing about hospital design and administration as well. That mix suggests a doctor interested not only in treating patients, but also in the larger systems and ideas that shaped modern medicine.

He died in 1926. Although he is not widely remembered outside specialist circles today, the works linked to his name preserve a picture of a physician engaged with ophthalmology, public health, and the organization of care in the early twentieth century.
