At the end of March 2013 Bob Moog was honored with an invitation to become a 2013 National Inventors Hall of Fame inductee by the United States Patent and Trademark Office. The honor is given to individuals who have “conceived, patented, and advanced” technologies affecting change in the modern world. The invention holds the Patent No. 3475623 and is usually referred to as the Moog Ladder Filter, the first voltage-controlled filter. It is this basic version of dynamic filter controlled at the keyboard—and pioneered in the Minimoog Synthesizer—that enables the electric pulse beating through nearly all modern mass-commercial popular music, from Kraftwerk and Michael Jackson to Brian Eno and Dr. Dre.
