Wilfred Lewis (October 16, 1854 [1] - December 29, 1929) [2] was an American mechanical engineer, inventor, director for the machine tool firm William Sellers & Co, and later president of the Tabor Manufacturing Company. He is known for his early work on the bending of gear teeths, and his later work on scientific management. In the late 19th century Lewis had developed a bending equation, which became standard for gear design. [3] The Lewis stress factor for gears is named after him.
Born in Philadelphia, Pennsylvania, Lewis graduated from the Massachusetts Institute of Technology in 1875, [4] and had spent his early career at the William Sellars and Company of Philadelphia. He had started his career as mechanic, draftsman, designer and assistant engineer, [5] and had worked his way up to one of the director of the machine tool firm. By 1900 he moved to the Tabor Manufacturing Company in Philadelphia, PA, where he was appointed president and introduced the Taylor system of shop management. [6] Over the years Lewis was a prolific inventors, who held over 50 patents. In his later life he became promoter of the Scientific management. [4]
Lewis was vice-president of the American Society of Mechanical Engineers from 1901 to 1903. [7] In 1910-12 Lewis was also one of the founding members of the Taylor Society, [8] and later its president. [4] Lewis was a recipient of the ASME Medal from the American Society of Mechanical Engineers in 1927. [9]
Lewis died a sudden death at sea in 1929 from apoplexy near Egypt, and was buried at sea. Lewis had been taking a trip around the world after he had attended the World Engineering Congress of 1929 in Tokyo, Japan. [4] Lewis had been married to Emily Sargent Lewis, a poet and suffragette, and they had five children. [10]
Lewis was a boyhood friend of Frederick Winslow Taylor, participated in the development of Taylor's work since the late 19th century, and became a promoter of scientific management in the first decennia of the 20th century. Taylor himself had developed his system of management at the Midvale Steel company. Afterwards he had introduced his system among others in the shops of the William Sellers and Company machine tool firm, sponsored by William Sellers himself, but this collapsed when Sellers retired. [11] As one of its directors Lewis had become acquainted with Taylor's system, but this didn't make a lasting impression. About their further interaction Merkle (1980) summarized:
Over the years Wilfred Lewis became strong believer and promoter of scientific management. About one of his latest stands, Kyle and Nyland (1993) summarized: [12]

Frederick Winslow Taylor was an American mechanical engineer. He was widely known for his methods to improve industrial efficiency. He was one of the first management consultants. In 1909, Taylor summed up his efficiency techniques in his book The Principles of Scientific Management which, in 2001, Fellows of the Academy of Management voted the most influential management book of the twentieth century. His pioneering work in applying engineering principles to the work done on the factory floor was instrumental in the creation and development of the branch of engineering that is now known as industrial engineering. Taylor made his name, and was most proud of his work, in scientific management; however, he made his fortune patenting steel-process improvements. As a result, scientific management is sometimes referred to as Taylorism.
Henry Laurence Gantt was an American mechanical engineer and management consultant who is best known for his work in the development of scientific management. He created the Gantt chart in the 1910s.
John Edson Sweet was an American mechanical engineer, inventor, professor, businessman and president of the American Society of Mechanical Engineers from 1884–1885. He is known for building the first micrometer caliper in 1873, for making tools, and for inventing the "straight line" engine.
Leon Pratt Alford was an American mechanical engineer, organizational theorist, and administrator for the American Society of Mechanical Engineers. known for his seminal work in the field of industrial management.
Henry Robinson Towne was an American mechanical engineer and businessman, known as an early systematizer of management. He donated several millions to philanthropy at his death, in 1924.
Carl Georg Lange Barth was a Norwegian-American mathematician, mechanical and consulting engineer, and lecturer at Harvard University. Barth is known as one of the foreman of scientific management, who improved and popularized the industrial use of compound slide rules.
William Sellers was a mechanical engineer, manufacturer, businessman, noted abolitionist, and inventor who filed more than 90 patents, most notably the design for the United States standard screw thread, the standard bolt and machine screw thread still used today. As president of the Franklin Institute in Philadelphia, Pennsylvania, Sellers proposed the adoption of a system of screw threads which was easier for ordinary mechanics and machinists to cut than a similar design by Joseph Whitworth. For many years, he led the machine tool firm of William Sellers & Co., which was a very influential machine tool builder during the latter half of the 19th century.
Frederick Arthur Halsey was an American mechanical engineer and economist, who was long-time editor of the American Machinist magazine, and particularly known for his 1891 article, entitled "The premium plan of paying for labor."

The Sellers family of Philadelphia and Delaware County, Pennsylvania, are a family of scientists and engineers. More members of the Sellers family and the closely related Peale family have belonged to the American Philosophical Society than any other family in the history of the United States, and the same is true of the Academy of Natural Sciences, the Franklin Institute, and the Pennsylvania Academy of the Fine Arts.
