Biography
Early life and education
Gilbreth was born in
Fairfield, Maine, on July 7, 1868. He was the third child and only son of John Hiram Gilbreth and Martha Bunker Gilbreth. His mother had been a schoolteacher. His father owned a hardware store and was a stockbreeder. When Gilbreth was three and a half years old his father died suddenly from pneumonia.
After his father's death his mother moved the family to

where good public schools existed. She opened a boarding house since a schoolteacher's salary would not support the family.
Gilbreth was not a good student. He attended Rice Grammar School, but his mother was concerned enough to teach him at home for a year. He attended Boston's
English High School, and his grades improved when he became interested in his science and math classes. He took the entrance examinations for the

, but wanted his mother to be able to give up the boarding house. He decided to go to work rather than to college.
Whidden Construction Company
Renton Whidden, Gilbreth's old Sunday School teacher, hired him for his building company. He was to start as a laborer, learn the various building trades, and work his way up in the firm. In July 1885 at age 17 he started as a

's helper.
As he learned
bricklaying he noticed the many variations in the bricklayers' methods and efficiency. This began his interest in finding "the one best way" of executing any task. He quickly learned every part of building work and contracting, and advanced rapidly. He took night school classes to learn mechanical drawing.
After five years he was a superintendent, which allowed his mother to give up her boarding house.
Using his observations of workmen laying brick, Gilbreth developed a multilevel
scaffold that kept the bricks within easy reach of the bricklayer.
He began patenting his innovations with this "Vertical Scaffold", then developed and patented the "Gilbreth Waterproof Cellar".
He made innovations in concrete construction,
as well. After ten years, at age 27, he was the chief superintendent.
When after ten years the Whiddens were unwilling to make him a partner, he resigned to start his own company.
Career as general contractor
Gilbreth founded his own commercial contracting firm on April 1, 1895. For the next fifteen years, "Frank B. Gilbreth, General Contractor" and two subsidiary companies would build some 100 large-scale projects across the United States (along with two in Canada), including full scale factories, paper mills, canals, dams and powerhouses. The largest such project was a complete paper mill constructed in 1907–08 in Canton, North Carolina. It was a $2 million facility consisting of more than thirty full-scale industrial buildings.
One Gilbreth construction project was the
Simmons Hardware Company's
Sioux City Warehouse. The architects had specified that hundreds of hardened concrete piles (based on Gibreth's own patents for design and installation) were to be driven in to allow the soft ground to take the weight of two million bricks required to construct the building. The "Time and Motion" approach could be applied to the bricklaying and the transportation. The building was also required to support efficient input and output of deliveries via its own railroad switching facilities.
Gilbreth held thirteen patents as an inventor, beginning in his years with the Whiddens, and had patent and product management offices in London and Berlin. Other than two projects in

, Canada, and a third that was abandoned after initial construction, he did not build any projects outside the United States.
Career as efficiency expert
Gilbreth changed careers to efficiency and management engineering with the close of his construction companies in about 1912. He eventually became an occasional lecturer at

, which houses his papers.
Gilbreth discovered his vocation as efficiency expert while still a young construction worker, when he sought ways to make
bricklaying faster and easier. During the later part of his contracting career, this grew into a collaboration with his wife,
Lillian Moller Gilbreth. Together they studied the work habits of manufacturing and clerical employees in all sorts of industries to find ways to increase output and make their jobs easier. He and Lillian founded a management consulting firm, Frank B. Gilbreth, Inc. (renamed
Gilbreth, Inc. after his death), focusing on such endeavors.
Gilbreth was also an adamant champion of the "cost-plus-a-fixed sum" contract in his building contracting business. He described this method in an article in Industrial Magazine in 1907, comparing it to fixed price and guaranteed maximum price methods. Many of his prolific advertisements throughout the era boast of and recommend this as "their special method of construction."

. His assignment was to find quicker and more efficient means of assembling and disassembling small arms. However, he was stricken with rheumatic fever and then pneumonia just weeks into his service, and spent four months in recovery before being discharged. The heart damage from this episode would contribute to his premature death six years later. According to Claude George (1968), Gilbreth reduced all motions of the hand into some combination of 17 basic motions. These included grasp, transport loaded, and hold. Gilbreth named the motions
therbligs — "Gilbreth" spelled (approximately) backwards. He used a motion picture camera that was calibrated in fractions of minutes to time the smallest of motions in workers.
Their emphasis on the "one best way" and therbligs predates the development of
continuous quality improvement (CQI), and the late 20th century understanding that repeated motions can lead to workers experiencing repetitive motion injuries.
Gilbreth was the first to propose the position of "caddy" (Gilbreth's term) to a surgeon, who handed surgical instruments to the surgeon as needed. Gilbreth also devised the standard techniques used by armies around the world to teach recruits how to rapidly disassemble and reassemble their weapons even when blindfolded or in total darkness.
Scientific management
The work of the Gilbreths is often associated with that of
Frederick Winslow Taylor

; Taylor was concerned primarily with reducing process times. The Gilbreths, in contrast, sought to make processes more efficient by reducing the motions involved. They saw their approach as more concerned with workers' welfare than Taylorism, which workers themselves often perceived as concerned mainly with profit. This difference led to a personal rift between Taylor and the Gilbreths which, after Taylor's death, turned into a feud between the Gilbreths and Taylor's followers. After Frank's death, Lillian Gilbreth took steps to heal the rift;
however, some friction remains over questions of history and intellectual property.
Fatigue study
In conducting their Motion Study method to work, they found that the key to improving work efficiency was in reducing unnecessary motions. Not only were some motions unnecessary, but they caused employee fatigue. Their efforts to reduce fatigue included reduced motions, tool redesign, parts placement, and bench and seating height, for which they began to develop workplace standards. The Gilbreths' work broke ground for contemporary understanding of ergonomics.
Legacy
Frank and Lillian Gilbreth often used their large family (and Frank himself) as
guinea pigs in experiments. Their family exploits are lovingly detailed in the 1948 book ''
Cheaper by the Dozen'', written by son Frank Jr. and daughter Ernestine (
Ernestine Gilbreth Carey). The book inspired a film and the title inspired a second and third unrelated film of the same name. The first, in 1950, starred
Clifton Webb and
Myrna Loy.
The second, in 2003, starred
