2. Company History and Business Evolution

Founded in 1938 by John H. Krehbiel Sr. and his wife, Molex started as a small plastics molding shop in Brookfield, Illinois. The company’s name was derived from the material “molex,” a thermoplastic used for insulation. During World War II, Molex shifted focus to producing essential components for military electronics, establishing its reputation for precision manufacturing. In the 1950s, Molex pioneered the first nylon connector, revolutionizing the industry with cost-effective and reliable interconnect solutions. The 1960s saw expansion into appliance and automotive markets, while the 1970s brought international growth with facilities in Europe and Asia. The 1980s and 1990s marked a period of aggressive acquisitions and diversification, including the purchase of Brad Harrison and Woodhead Industries, strengthening its industrial and sensor portfolios. The turn of the millennium saw Molex becoming a global electronics giant, with a focus on miniaturization and high-speed data transmission. In 2013, Molex was acquired by Koch Industries, a move that provided strategic capital and operational synergies while allowing Molex to maintain its entrepreneurial culture.
