Frank Bunker Gilbreth, Sr. was an early advocate of scientific management and pioneer of motion study. He was born in Maine and had no formal education beyond high school. He began as a bricklayer and later became a building contractor, inventor, and management engineer. Gilbreth proposed that surgical nurses hand instruments to surgeons and developed standard techniques for teaching military recruits to assemble and disassemble weapons rapidly. He received posthumous honors from engineering and management associations. Gilbreth died of heart failure in 1924 at age 55.

1. Frank Bunker Gilbreth, Sr. (July 7, 1868 - June 14,
1924)
Biography:
He was an early advocate of scientific management and a
pioneer of motion study, but is perhaps best known as the
father and central figure of Cheaper by the Dozen written by
Frank Bunker Gilbreth, Jr.
Gilbreth was born in Fairfield, Maine to Joseph Hiram and
Martha Gilbreth. In 1904, he married Lillian Evelyn Moller
and fathered twelve children. He had no formal education
beyond high school. He began as a bricklayer, Later became
a building contractor, an inventor, and ultimately into
management engineer.
Gilbreths were, primarily, scientists who sought to teach
managers that all aspects of the workplace should be
constantly questioned, and improvements constantly
adopted.
Gilbreth was the first to propose that a surgical nurse serve
as a caddy (Gilbreth's term) to a surgeon, by handing
surgical instruments to the surgeon. Gilbreth also came up
with the standard techniques used by armies around the
world to teach recruits how to rapidly disassemble and
reassemble their weapons
He was posthumously honored with the Gantt Gold Medal
in 1944 from the American Society of Mechanical Engineers
and the American Management Association.
Gilbreth died of heart failure on June 14, 1924, at age 55.

2. Ideology
 Although the work of the Gilbreths is often associated with that of Frederick
Winslow Taylor, there was an important philosophical difference between
them. The symbol of Taylorism was the stopwatch; Taylor was primarily
concerned with reducing process times. Whereas The Gilbreths 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 primarily concerned 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 (Price
1990); however, some friction remains over questions of history and
intellectual property.
 Opposed to Taylor, who held an antagonistic and patronizing view of the
laborer of the day, both Gilbreths were more sympathetic to their concerns.
Frank Gilbreth had belonged to a union and was disposed to consider that the
cooperation of the worker was necessary if any scientific reorganization was to
succeed. It is in large measure due to Lillian's influence and training that the
Gilbreths' form of scientific management always had a more developed view of
the worker, and his or her interests, than Taylor's simplistic view of a worker
as driven solely by pay.
