In the late-twentieth century in the United States, Catherine DeAngelis was a pediatric physician, researcher, and editor of multiple medical journals. During her time with the Journal of the American Medical Association, DeAngelis became the journal’s first female editor. At Johns Hopkins University in Baltimore, Maryland, she studied how physician-nurse interactions affected patient care, how immunizations and adolescent pregnancy affected children, and how medications affected men and women differently. She also worked to reduce gender inequality in the practice of medicine by publishing articles that addressed the pay gap between men and women at Johns Hopkins. Throughout her career, DeAngelis advocated for equality between men and women in the medical field and supported equal treatment of women as patients and as practitioners of medicine. By doing so, she helped women become more central participants in medicine and therefore helped increase the focus on women's health in medicine.
