“As an instrument maker, as well as a player, Pruefer, self-taught, was notably successful. The Pruefer Company in Providence, Rhode Island, was known particularly for its mass-produced, Boehm-system clarinets. Pruefer's musical and industrial reputation was quite the same as that of William Mueller-generous, but driven and keenly competitive. The two men were business associates during the World War I era. The portrait was taken in Markneukir-chen at a time when Pruefer worked in the Moennig shop.”

1906 Gustav “Gus” Pruefer started his first clarinet company. He was born in USA to a German immigrant family that manufactured jewelry (still in jewelry business in Providence, RI.)
1914 Pruefer merged with Penzel and Mueller to form Penzel, Mueller and Pruefer
1920 Penzel died and Pruefer left the company
1920 Gus Pruefer traveled to Markneukirchen Germany to help Hans Moennig modernize his factory
1921 Gus restarted Pruefer Mfg. Co. Providence, RI with Hans Moennig on board.
US Patent issued 1931 for a complex metal liner for wood clarinets, allowing for expansion of the wood (Pat. #1801690). It looks impractical, but it shows the inventive side of Gus Pruefer.
1942 ad showed Pruefer ebonite clarinet with nickel-silver lining in upper joint, not yet named “Silver Throat”
1942 Pruefer sold the company to an apprentice (Ref: Newsletter Of The American Musical Instrument Society, June 1988)
1955 ad showed the instrument with the trade name “Silver Throat”
1960’s degraded to smaller bore in lower joint, nickel-plated keys, and eventually a plastic body.
1976 Factory in Providence, RI burned down … RIP!
