Don L. Smithers is a music historian and performer. He is one of the few trumpeters currently committed to playing the baroque trumpet as it is known to have been played in the 17th and 18th centuries. In 1979 he left his position as Director of the Collegium Musicum at the Royal Dutch Conservatory of Music in the Hague to write a large treatise on the music, history, symbolism, manufacture, and use of the classic trumpet from antiquity until the era of Beethoven. This work is still in progress.
