Richard Morrow

Richard Harold Morrow Jr. was a professor at Johns Hopkins Bloomberg School of Public Health.

His father, Richard Morrow, was an inventor who sold vacuum cleaners of his own design, and a commercial paper bag opener for fast food restaurants.

He also spent a year working in Many Farms, Arizona, treating members of the Navajo tribe, while he and his wife lived in a converted railroad car.

The Morrows then moved to Uganda, where his wife was a Peace Corps nurse, and he studied infectious diseases such as buruli ulcers.

This was adopted by the World Health Organization, and the calculation of disability-adjusted life years is derived from this.
