Lewis B. Swift
Lewis B. Swift was an American engineer and manufacturing executive who served as the sixth President of the Taylor Instrument Companies from 1938 to 1951. Guiding the company through the intense production mobilization of World War II, Swift oversaw Taylor’s top-secret instrumentation work for the Manhattan Project at Oak Ridge, Tennessee, earned multiple Army-Navy “E” Awards for production excellence, and directed the company's post-war conversion to automated industrial process control.
Early Engineering Career & Rise at Taylor
Trained as a mechanical engineer, Swift joined the Taylor Instrument Companies during the early twentieth-century expansion of its Ames Street manufacturing campus in Rochester, New York.
Over several decades, Swift rose through the company’s technical, administrative, and factory management divisions:
- Managed critical precision engineering programs as Taylor expanded into industrial recording thermometers, pyrometers, and pneumatic control valves.
- Assumed senior operational responsibility throughout the 1920s and 1930s, working closely with long-time president Herbert J. Winn to modernize plant efficiency and manufacturing standards.
- Promoted to senior executive rank during the Great Depression, helping keep the firm financially sound and technologically innovative.
Presidency (1938–1951)
In November 1938, Lewis B. Swift was formally elected President of the Taylor Instrument Companies. His election marked an orderly generational transition: outgoing president Herbert J. Winn assumed the newly created role of Chairman of the Board of Directors.
Swift’s thirteen-year presidency became one of the most consequential in the company's hundred-year history.
World War II Defense Mobilization
With the outbreak of the Second World War, Swift directed the total conversion of the Ames Street plant to military and defense manufacturing:
- Combat & Aviation Instruments: Taylor manufactured tens of thousands of sensitive altimeters, airspeed indicators, rate-of-climb indicators, and manifold pressure gauges for Allied bombers and pursuit aircraft.
- Naval & Maritime Instrumentation: Built high-pressure steam gauges, deep-sea depth gauges for submarines, and meteorological equipment for naval combat vessels.
- Government Honors: Under Swift’s leadership, the War Department and Navy Department awarded the Ames Street workforce the prestigious Army-Navy “E” Award for excellence in wartime production, followed by renewal stars.
The Manhattan Project (1943)
In May 1943, Swift was one of the select industrial executives summoned to clandestine meetings in New York City by the United States Army Corps of Engineers Manhattan Engineer District.
Taylor was selected as the prime contractor for process-control instrumentation for the K-25 gaseous diffusion uranium enrichment plant at Oak Ridge, Tennessee:
- Swift mobilized Taylor's top research physicists, chemical engineers, and precision instrument makers under stringent military secrecy.
- Taylor designed, engineered, and mass-produced the specialized, leak-tight, ultra-sensitive pressure gauges, vacuum monitoring instruments, and pneumatic control valves required to handle volatile uranium hexafluoride gas.
- The success of the gaseous diffusion process rested directly upon the continuous pneumatic monitoring systems engineered at Ames Street under Swift’s oversight.
Post-War Reconversion & Centennial
Following the 1945 Allied victory, Swift steered the company through a rapid, disciplined transition back to civilian and industrial markets:
- Process Control Leadership: Expanded Taylor’s line of automated continuous-process control systems for the fast-growing petroleum refining, chemical synthesis, plastics, and pharmaceutical sectors.
- Centennial Milestone (1951): Presided over the company’s 100-year centennial anniversary celebration in 1951, honoring the founding of Kendall & Taylor in 1851 and recognizing veteran employees with commemorative service awards.
Chairman of the Board & Industry Leadership
In late 1951, having guided the corporation through thirteen years of wartime expansion and post-war prosperity, Swift retired from the presidency. He was elected Chairman of the Board of Directors, succeeding Herbert J. Winn, while Vice President Raymond E. Olson was elected President to head executive operations.
Throughout and following his presidency, Swift was a nationally recognized business and financial figure:
- Federal Reserve Bank of New York: In the late 1940s and early 1950s, Swift served as a Class B Director of the Federal Reserve Bank of New York, representing industrial and commercial enterprises across the Second Federal Reserve District.
- Scientific Apparatus Makers Association (SAMA): Active in national trade governance, Swift served in executive leadership roles within SAMA, advocating for domestic precision instrument standards, tariff policies, and technical training.
