Lillian Evelyn Gilbreth (née Moller; May 24, 1878 – January 2, 1972) was an American psychologist, industrial engineer, consultant, and educator who was an early pioneer in applying psychology to time-and-motion studies. She was described in the 1940s as "a genius in the art of living."
Gilbreth, one of the first female engineers to earn a Ph.D., is considered to be the first industrial/organizational psychologist. She and her husband, Frank Bunker Gilbreth, were efficiency experts who contributed to the study of industrial engineering, especially in the areas of motion study and human factors.
Cheaper by the Dozen (1948) and Belles on Their Toes (1950), written by two of their children (Ernestine and Frank Jr.) tell the story of their family life and describe how time-and-motion studies were applied to the organization and daily activities of their large family. Both books were later made into feature films.
Lillie Evelyn Moller was born in Oakland, California, on May 24, 1878, to Annie (née Delger) and William Moller, a builder's supply merchant. She was their second child and the eldest of the family's nine surviving children. Their first child, Anna Adelaide, had died at age four months. Her maternal grandfather Frederick Delger was a German immigrant who became the richest man in Oakland.
Educated at home until the age of nine, Moller began formal schooling in the first grade at a public elementary school and was rapidly promoted through the grade levels. She was elected vice president of her senior class at Oakland High School and graduated with exemplary grades in May 1896.
Although Moller wanted to go to college, her father was opposed to such education for his daughters, but she persuaded her father to let her try college for a year and was admitted to the University of California.
After her first-year grades were near the top of her class, her father agreed to allow her to continue her studies. She commuted from home on the streetcar, and in the evenings helped her mother with the household and her siblings with their homework. She majored in English, also studying philosophy and psychology, and had enough education courses to earn a teaching certificate. She also won a prize for poetry and acted in student plays. In the spring of her senior year the new university president, Benjamin Ide Wheeler, asked her to be one of the student speakers at the commencement ceremonies. On May 16, 1900, she graduated from the university and became the first woman to speak at a University of California commencement. The title of her speech was "Life: A Means or an End".
Moller had begun to think of a professional career rather than staying at home after graduation. She now wished to be called Lillian because she felt it was a more dignified name for a university graduate, and she left home to enroll in graduate school at Columbia University in New York City. Her literature professor Charles Gayley had suggested she study there with Brander Matthews. Graduate enrollment at Columbia was almost half women at the time, but Matthews would not allow them in his classes. Instead, she studied literature with George Edward Woodberry. A lasting influence was her study with the psychologist Edward Thorndike, newly appointed at Columbia. Though she became ill with pleurisy and was brought home by her father, she continued to refer to Thorndike in her later work. Back in California, she returned to the University of California in August 1901 to work toward a master's degree in literature. Under the supervision of Gayley, she wrote a thesis on Ben Jonson's play Bartholomew Fair, and received her master's degree in the spring of 1902.
Moller began studies for a PhD at the University of California, but took time off to travel through Europe in the spring of 1903. Following her marriage to Frank Bunker Gilbreth in 1904 and relocation to New York, she completed a dissertation for a doctorate from the University of California, Berkeley, in 1911, but was not awarded the degree due to her noncompliance with residency requirements for doctoral candidates. The dissertation was published as The Psychology of Management: The Function of the Mind in Determining, Teaching and Installing Methods of Least Waste in 1914.
After the Gilbreths relocated their family to Providence, Rhode Island, Lillian enrolled at Brown University. She earned a Ph.D. in applied psychology in 1915, making her the first of the pioneers of industrial management to have a doctorate. The topic of her dissertation was efficient teaching methods and titled Some Aspects of Eliminating Waste in Teaching. Her doctoral dissertation was published in 2019 as a book titled Eliminating Waste in Teaching (ISBN 978-1-7320191-0-2).
Lillian Moller met Frank Bunker Gilbreth in June 1903 in Boston, Massachusetts, en route to Europe with her chaperone, who was Frank's cousin. He had apprenticed in several building trades in the East and established a contracting business with offices in Boston, New York, and London.
The couple married on October 19, 1904, in Oakland, California, and settled in New York. They later moved to Providence, Rhode Island, and eventually relocated their family to Montclair, New Jersey.
As planned, the Gilbreths became the parents of a large family that included twelve children. One died young in 1912; one was still-born in 1915; and eleven of them lived to adulthood, including Ernestine Gilbreth, Frank Bunker Gilbreth Jr., and Robert Moller Gilbreth.
After Frank died of a heart attack on June 14, 1924, Lillian never remarried.
For just under 50 years, Gilbreth's career combined psychology with the study of scientific management and engineering. She also included her perspectives as a wife and mother in her research, writing, and consulting work. Gilbreth became a pioneer in what is now known as industrial and organizational psychology. She helped industrial engineers recognize the importance of the psychological dimensions of work. In addition, she became the first American engineer ever to create a synthesis of psychology and scientific management. (Gilbreth introduced the concept of using psychology to study management at the Dartmouth College Conference on Scientific Management in 1911).
In addition to jointly running Gilbreth, Incorporated, their business and engineering consulting firm, Lillian and Frank wrote numerous publications as sole authors, as well as co-authoring multiple books and more than fifty papers on a variety of scientific topics. However, in their joint publications, Lillian was not always named as a co-author, possibly due to publishers' concerns about naming a female writer. Although her credentials included a doctorate in psychology, she was less frequently credited in their joint publications than her husband, who did not attend college.
The Gilbreths were certain that the revolutionary ideas of Frederick Winslow Taylor would be neither easy to implement nor sufficient; their implementation would require hard work by engineers and psychologists to make them successful. The Gilbreths also believed that scientific management as formulated by Taylor fell short when it came to managing the human element on the shop floor. The Gilbreths helped formulate a constructive critique of Taylorism; this critique had the support of other successful managers.
In 1934, Gilbreth organized the energy-saving kitchen, along with the nursery and the clothery for America's Little House. Designed by architect, Roger Bullard, it was a project from Better Homes in America for a two-story suburban type home to be situated in New York City on Park Avenue and 39th Street, amongst all the skyscrapers.
