More than fifty-seven years ago co-foundersMarlan and Rosemary Bourns set up shop in their tiny 384 square-foot garage in Altadena, California. Their idea to provide a method of accurately determining an aircraft's vertical position solved a crucial problem for pilots. The invention of the first miniature linear motion and vane position potentiometers propelled their tiny business into a global corporation, manufacturing a range of products that impact almost every aspect of today's electronics industry. From its earliest days, Bourns established abenchmark for quality, value, and innovation....
