Shure Timeline: Milestones From 1925 To 2000

A look at the wealth of achievements of one of the most successful and longest enduring in professional audio.

1942-1944: T-30 throat microphone, HS-33 and HS-38 headset microphone, M-CI microphone for oxygen masks, and Battle Announce Microphone are all made for the military. Using T-30s, bomber crews could communicate over the noise inside the planes. Shure adopts strict military standards (MILSPEC) as the standard of reliability for all Shure microphones.

1946: Shure is the largest producer of phonograph cartridges in the U.S., supplying cartridges to major phonograph manufacturers, including Philco, RCA, Emerson, Magnavox, Admiral, and Motorola.

Also in 1948, Harry S Truman celebrates his surprise election victory with Shure 55’s in the foreground.

1946: Shure Brothers Company becomes Shure Brothers Incorporated.

1948: First phonograph cartridge capable of playing both long-playing (LP) and 78 rpm (revolutions per minute) records.

1951: Unidyne 55S is a smaller version of the Unidyne 55.

1952: First Shure ribbon microphone, Model 300.

1953: First wireless microphone system for performers, called the Vagabond. Powered by two hearing aid batteries, the system could transmit within a “performance circle” of approximately 700 square feet.

The familiar “mic of the presidents” – the SM57.

1954: M12 Dynetic Phono Reproducer is a tone arm/phono cartridge combination that set a new industry standard with its tracking force of only one gram.

First mobile communications microphone designed to also function as a loudspeaker.

1956: Shure moves from downtown Chicago to its present corporate headquarters in Evanston, Illinois.

1958: M3D phonograph cartridge is the world’s first cartridge to successfully meet performance requirements of stereo recording.

1959: Unidyne III microphone is the first high-quality unidirectional microphone that is used by speaking into the end (“end-firing”) rather than the side of the microphone. It was the predecessor to the SM57.

1965: SM57 dynamic microphone is rugged and reliable with a clean, natural sound. Into 2000, it continues to be the U.S. President’s lectern microphone.

1966: Shure SM58 (“SM” for “studio microphone”) is adopted by rock-and-roll musicians, who find it offers the right combination of rugged reliability and excellent sound quality; it becomes the standard for live performance vocals. V15 Type II, the first computer-designed phono cartridge, features superior tracking ability.
