Georg Neumann introduced the world’s first commercially available condenser microphone, the Neumann CMV, and officially put his new company Neumann on the map. The interchangeable capsules offered different directional patterns, and it was hard to miss at 40 cm tall and 9cm in diameter. Due its large profile, it became known as the “Neumann bottle.” The easily recognizable CMV 3 is often seen in historical photographs of public events in Germany, many taken during World War II.
