From Wikipedia: "Seymour DeKoven (25 November 1903 – 29 October 1984), generally known simply as DeKoven, was a United States classical music radio personality of the 1950s, 1960s, 1970s, and early 1980s. Because of his penchant for mixing short musical segments with enthusiastic commentary, he could be called a "classical music disk jockey." His unique style was utterly different from that of any popular-music disk jockey, but was also worlds apart from the dignified manner of other classical radio notables such as Robert J. Lurtsema of WGBH, Boston, and Robert Conrad of WCLV, Cleveland. He played exclusively music of the baroque and rococo eras. He is identified with the word "barococo" in reference to music of that time, a coinage that became familiar and understood, but was never widely adopted. In his obituary, The New York Times called him "passionately opinionated." In the U. S. prior to the 1960s, baroque music was known mostly to musicians and scholars, and was relatively unfamiliar to the general classical listening audience. DeKoven's broadcasts coincided with what is sometimes referred to as the "1960s baroque revival," a sharp rise in popular interest in the music."
