b. 1890
A physician and medical researcher, this early 20th-century writer is best known for co-authoring a close study of influenza at Yale in the years following the 1918 pandemic. Her work offers a direct window into how doctors of the time tried to understand one of the era’s most devastating diseases.

by M. C. (Milton C.) Winternitz, Frank P. McNamara, Isabel M. Wason
Born in 1890, Isabel M. Wason appears in historical records as Dr. Isabel Mary Wason. She is credited as one of the authors of The Pathology of Influenza (1920), a medical study published by Yale University Press with M. C. Winternitz and Frank P. McNamara.
The book identifies its authors with the Brady Laboratory of Pathology and Bacteriology at Yale University School of Medicine and the New Haven Hospital, placing her work in an important medical research setting just after the 1918 influenza pandemic. A Yale historical photo record from 1921 also names Dr. Isabel M. Wason among the department staff.
Very little biographical detail seems to be widely available online beyond these research and archival traces. Even so, her surviving publication shows her as part of the scientific effort to document and understand influenza at a moment when that knowledge mattered urgently.
