Margaret Bright, a sociologist and demographer who conducted public health studies, died on Dec. 28 at her home in the Broadview Apartments in the Tuscany-Canterbury neighborhood. She was 100 years old.
Her niece, Renee Bright Mullins of Clovis, Calif., said no cause of death had been established.
“Her work influenced the growth of some of the pillars of public health, including social determinants of health, urban health, health services research, population dynamics, and longitudinal health studies,” said Karen Kruse Thomas, the staff historian at the Johns Hopkins Bloomberg School of Public Health. “Few persons realized how influential she actually was.”
