November 15, 2017 @ 6:00 pm - 8:45 pm

Michael Pettersen Shure, Inc

Introduced in 1939 and still being manufactured today, the Shure Unidyne was the first unidirectional microphone using a single dynamic element. The presentation provides an overview of the Unidyne’s unique position in the history of 20th century broadcast, politics, and entertainment, plus the amazing story of the 24 year old immigrant from the Ukraine who invented the Unidyne and earned his first of over 100 patents for audio technology.
The IEEE Milestones in Electrical Engineering and Computing Award was presented to Shure in January, 2014, for the development of the Unidyne. The award recognized the technical breakthrough in offering lower cost, greater reliability, and improved performance for communications. The IEEE Milestone Award honors pioneering work in engineering.

Employed by microphone manufacturer Shure Incorporated since 1976, Michael is the Director of Corporate History. He is a contributing author to the 1,550 page reference tome “Handbook for Sound Engineers – Third/Fourth Edition.” He has presented technical white papers to the Audio Engineering Society, National Association of Broadcasters, Acoustical Society of America, National Systems Contractor Association, European Institute of Acoustics, Voice of America, and White House Communications Agency. In 2014, he authored the definitive history of the Shure Unidyne Microphone. Fascinated by music, sound, and audio technology since building a crystal radio set as a lad, Michael Pettersen has a Bachelor of Arts in Music Theory from the University of Illinois in 1974.
