Hospitalization & Surgery

Decades before Evidence-Based Medicine forced doctors to reveal both the benefits and risks of interventions, Dr. Mendelsohn taught his readers to investigate the dangers of a proposed treatment, and not just accept their doctor’s reassurances.

Women & Medicine

Dr. Mendelsohn believed that a combination of misogyny and professional arrogance led doctors to subject women to dangerous medical treatments and unnecessary, disfiguring surgery.

Judaism & Medicine

Throughout his life, Dr. Mendelsohn drew upon his traditional Jewish education and values. A graduate of the College of Jewish Studies in Chicago, he encouraged doctors to respect their own religious and ethical wisdom as a counterbalance to what he called the idolatrous church of modern medicine.
