Founding Story

Arthur Schmitt founded the American Phenolic Corporation in Chicago in 1932. He used a new plastic, Bakelite, to make better tube sockets for the fast-growing radio industry. During World War II the US military needed reliable, mass-produced electrical connectors for aircraft and communications equipment, and Schmitt's company supplied rugged, waterproof connectors. Meeting the military's standards for reliability shaped the engineering culture the company still has.

Background

Arthur J. Schmitt was born on June 14, 1893, in Chicago, Illinois, the third child of Henry W. and B. Elizabeth Schmitt. As a youth, he attended St. Ignatius High School run by the Jesuits and developed a passion for building and tinkering, constructing wagons from crates and baby-carriage wheels. At age 17 in 1910, he built a 'Wind Machine' by attaching an airplane engine and propeller to a stripped-down car chassis, achieving speeds of 50 mph on straightaways. After experimenting with radios, Schmitt discovered that Bakelite, a phenolic plastic, could be molded to form superior electrical sockets. He founded Walnart Mfg. Co. in 1923 with $5,000 and partner Walter Horn, producing bakelite radio tube sockets. After leaving that venture in 1932 due to Depression-related struggles and a merger dispute, Schmitt filed a patent in August 1932 for a new molded phenolic socket and founded American Phenolic Corporation in November 1932. His founding philosophy of 'no compromise' on quality and concentration on electronic components rather than elaborate assemblies established the engineering culture that would define Amphenol for decades. Schmitt took the company public in 1945 and led it through the transition from wartime to peacetime operations before his death.

Role at Amphenol Corporation

Amphenol was founded in Chicago in 1932 by an effective, pragmatic entrepreneur named Arthur J. Schmitt. The founding of the company occurred during the nadir of the Great Depression, a time when launching a new manufacturing business was considered borderline suicidal. However, Schmitt, a former salesman and engineer, recognized an unmet need emerging in a brand new, disruptive industry: commercial radio. In the early 1930s radios were transitioning from expensive pieces of furniture into smaller, mass-market consumer appliances. A major bottleneck in the mass production of these radios was the vacuum tube socket. The sockets at the time were made of Bakelite or ceramic which were brittle, expensive to manufacture, and prone to breaking during assembly. Schmitt invented an influential new method for manufacturing these sockets using a significantly cheaper, more durable plastic material. He named his new enterprise the 'American Phenolic Corporation' (which was later officially shortened to Amphenol). His innovation reduced the cost of radio assembly, and his company exploded in growth. The foundational turning point for Amphenol, however, occurred during World War II. As the U.S. military rapidly mobilized, it desperately needed durable, standardized electronic connectors for its new fleets of aircraft, radar systems, and radios, equipment that had to survive extreme conditions. Amphenol pivoted entirely to military production, working closely with the Department of Defense to design and manufacture millions of specialized, ruggedized connectors. This baptism by fire established Amphenol's enduring reputation for extreme reliability and precise engineering, transforming Arthur Schmitt's depression-era startup into the foundational supplier of physical connectivity for the modern global military-industrial complex.

R. Adam Norwitt

Chairman, President and Chief Executive Officer

2009 – Present

R. Adam Norwitt has been Amphenol's chief executive since January 1, 2009 and added the role of chairman of the board in 2026. Net sales grew from $2.82 billion in 2009 to $23.09 billion in fiscal 2025 and the GAAP operating margin reached a record 25.4%. He has kept the decentralized operating model of roughly 150 business units in place while running an acquisition program that included Carlisle Interconnect Technologies in 2024, CommScope's outdoor wireless and distributed antenna businesses, Rochester Sensors and Trexon in 2025, and the $10.5 billion CommScope Connectivity and Cable Solutions purchase completed in January 2026. Norwitt holds a bachelor of science in international politics from the Georgetown University School of Foreign Service, a juris doctor from the University of Michigan Law School and an MBA from INSEAD, and practiced corporate law before joining Amphenol in 1998.

Former Chief Executive Officer and Chairman

1996 – 2008

Martin H. Loeffler was Amphenol's chief executive from 1996 to 2008, president from 1987 to 2006 and chairman of the board from 1997 until he retired from the board at the May 2026 annual meeting. He built the decentralized operating model and the acquisition driven growth strategy that define the modern company, expanded manufacturing in Asia-Pacific and Europe, and moved Amphenol into sensors and high speed interconnects.

Arthur J. Schmitt

Founder and Chief Executive Officer

1932 – 1964

Arthur J. Schmitt founded American Phenolic Corporation in Chicago in 1932 and led it as chief executive until 1964. He built the company on a molded phenolic radio tube socket, added the 75 series microphone connector and a lock-in tube socket in 1936, and turned it into the primary supplier of AN circular connectors for American military aircraft, radar and field radios during the Second World War. He took the company public in 1945 and then moved it into commercial aviation, broadcasting and telephone network work as defense orders fell away.

Who Founded Amphenol? FAQ

Who founded Amphenol and in what year was the company established?

Amphenol was founded in 1932 in Chicago, Illinois, by inventive industrial entrepreneur Arthur J. Schmitt.

Where does the name 'Amphenol' originate?

The name 'Amphenol' is a portmanteau derived from 'American Phenolic Corporation', combining 'American' with 'bakelite phenolic resin', the groundbreaking plastic compound used in Schmitt's earliest molded radio tube sockets.

What was Arthur J. Schmitt's initial breakthrough product in 1932?

Arthur Schmitt invented the first single-piece molded phenolic radio tube socket, replacing fragile multipiece ceramic sockets and making radio manufacturing faster, more durable, and significantly less expensive during the Great Depression.

How did Amphenol support Allied military production during World War II?

During the Second World War Amphenol was a primary manufacturer of ruggedized multipin circular AN connectors and coaxial radio frequency connectors used in radar systems, bombers and field radios. Its engineers Paul Neill and Carl Concelman developed the BNC connector later, in 1951.

What was Arthur J. Schmitt's philanthropic and social legacy?

Arthur Schmitt was a dedicated philanthropist who established the Arthur J. Schmitt Foundation in 1941 to fund university scholarships, leadership training, and educational programs across the American Midwest.

Where did Amphenol establish its primary manufacturing plants in the mid-20th century?

Amphenol expanded from Chicago into plants in Cicero, Illinois, Danbury, Connecticut, and Sidney, New York, the last of which became a major aerospace and military connector facility.

What coaxial connector standards did Amphenol engineers co-invent for the military?

Amphenol engineers co-invented and standardized military-grade RF connectors, including the Type N connector (named after Paul Neill of Bell Labs) and the ubiquitous BNC (Bayonet Neill, Concelman) connector widely used in electronics today.

When did American Phenolic Corporation become Amphenol Corporation?

The company was renamed Amphenol Electronics Corporation in 1942, formalizing the short name customers already used for American Phenolic Corporation, and traded as Amphenol-Borg Electronics after the 1958 merger with the George W. Borg Corporation.

Who founded Amphenol?
