75 Years of Progress


For the past 75 years, visionary engineers and inventors at Brüel & Kjær have been responsible for innovative breakthroughs and many world-firsts. We have a long and impressive track record and, as we look back, we wanted to share with you some of the highlights.
“Running a business is about having fun. Having fun is the best way to use your skills. We wanted talented people who could think for themselves, were creative and also a bit lucky.”
