Jr. Lewis H. Adler

Born in 1864, Lewis H. Adler Jr. was an American doctor whose published work places him in Philadelphia medical circles in the late 1800s and early 1900s. An 1889 medical report identifies him as a resident physician at University Hospital in Philadelphia, showing that he was active in hospital practice early in his career.

Adler is best remembered as the author of Fissure of the Anus and Fistula in Ano, a specialized medical book first published in 1892. The title page describes him as an instructor in diseases of the rectum at the Philadelphia Polyclinic and College for Graduates in Medicine, which suggests a career focused on both teaching and the treatment of colorectal disease.

His name also appears in connection with other medical writing, including work on anesthesia and case reports, and records linked to the American Proctologic Society place him among physicians involved in the growing specialty of rectal medicine. He died in 1934. No suitable verified portrait image could be confirmed from the sources reviewed.
