In 1954, Walter Werner Fischer founded the company W. W. Fischer in a garage in Morges, Switzerland. An entrepreneur at heart, he recognized a customer need for rugged connectors and developed the first high-quality sealed connector, designed for use in industrial applications. Less than a decade later, he filed an international patent for his pushpull locking system and developed the world’s first hermetic connector.
