History of Amphenol
- Founded: 1932
- Founders: Arthur J. Schmitt
Arthur J. Schmitt founded American Phenolic Corporation in Chicago in 1932 making phenolic tube sockets, then moved into military radio connectors during World War II and relocated to Connecticut under the Amphenol name.
The connector business grew through military and industrial markets until a 1987 management buyout set up the modern company, which went public in 1991 and began its acquisition run.
Norwitt's era since 2009 built it into the industry's consolidator: dozens of bolt-on buys culminating in the CommScope transactions, the outdoor wireless and Andrew deals in 2024-2025, then the $10.5 billion CCS acquisition completed January 9, 2026, the largest in company history, adding fiber optic capabilities for AI data centers.
