Jensen Napa CA sidewalk monument.
Locals and tourists pass by this Napa California sidewalk monument daily. Like many ignored sidewalk/roadside monuments, it marks a historical figure. This concrete and metal fixture pays homage to the history of audio pioneer Peter L. Jensen.
Peter Jensen is much to audio as Henry Ford is to the automobile. I was reminded of his place in audio history when I came across his sidewalk monument.
In 1915, Jensen unveiled and demonstrated his groundbreaking dynamic loudspeaker in front of a crowd of 75,000 San Franciscans— more than the attendance at the 2025 Super Bowl. Peter Jensen established the dynamic speaker as the technology utilized in nearly all audio systems. Who can lay claim to creating such a successful promotional event today?
As a young audio salesman, I sold cases of Jensen Coax and Triax car audio speakers, unaware of Peter Jensen’s achievements. In time I came to recognize his life’s work.
