Lillian Moller Gilbreth

Born in Oakland, California, in 1878, Lillian Moller Gilbreth became one of the most influential figures in early industrial engineering and applied psychology. She studied at the University of California, Berkeley, and later at Brown University, building an unusual career at a time when very few women were recognized in engineering or management.

Working closely with her husband, Frank Bunker Gilbreth, she helped develop time-and-motion study methods designed to reduce wasted effort and improve the way work was done. What made her stand out was her focus on the human side of efficiency: she brought psychology into the study of work and is often remembered as an early pioneer in industrial psychology and ergonomics.

After Frank Gilbreth's death, she continued her career as a consultant, educator, and public thinker. She also became widely associated with practical improvements in daily life, especially household design and labor-saving ideas, showing that careful observation and smart design could make ordinary tasks easier for millions of people.
