This past week, the world lost a legend in the audio recording field with the death of Wilma Cozart Fine, age 82. The name may not be familiar to many. But if you grew up in the 1960s or 1970s, chances are your family owned at least one of the recordings Ms. Fine produced for the Mercury label – perhaps the 1812 Overture sonic blockbuster featuring the Minneapolis Symphony Orchestra (and also featuring real cannons and bells) that would become the first classical album to sell more than one million copies.

A native Mississippian who grew up in Ft. Worth, Texas, Wilma Cozart graduated with college degrees in Music and Business, then went to work in the late 1940s for the newly reorganized Dallas Symphony as personal secretary to the orchestra’s new music director, the fiery Hungarian conductor Antal Dorati. The Dallas Symphony managed to secure a recording contract with RCA Victor – highly unusual for such a young ensemble – and proceeded to release a number of praised recordings including the Bela Bartok Violin Concerto #2 with Yehudi Menuhin.

When Dorati took up a new position as music director of the Minneapolis Symphony Orchestra, Cozart decamped to there as well. Shortly thereafter, she was retained by Mercury Records in New York City to manage the label’s newly formed classical record division.

Using her orchestra management acumen, Cozart, all of 24 years old, snagged a recording contract for Mercury with the lauded Chicago Symphony Orchestra – the first of several exclusive contracts she would negotiate with orchestras in Minneapolis, Detroit and Rochester.

The debut classical recording produced by Mercury’s sound engineers led by C. Robert Fine was Mussorgsky’s Pictures at an Exhibition, and it caused a sensation in the music world when it was released in 1951. It was widely praised as the best-sounding classical recording made up to that time, with the New York Times reporting that the realism and clarity of the recording made it seem as if the listener was “in the living presence of the performers.” Sensing the marketing power of this description, Cozart would adopt the “Living Presence” moniker for the entire Mercury classical catalog.

The secret to making the Mercury classical records was simple in concept yet quite challenging to implement: A single microphone was painstakingly tested for positioning in the auditorium above and in front of the orchestra at the precise location where the sound would “bloom” most naturally. (Later, when stereophonic disks were introduced, three microphones would be used during recording and then mixed down to two channels.)

Cozart, who married Robert Fine in 1958, learned the craft (and art) of record production from the ground up. In the end, she and her team would release several hundred Mercury classical recordings before the label was acquired by Dutch-based Philips.

It is difficult to cite another instance in which a classical record producer such as Ms. Fine has had such a positive impact on the reputations of the conductors and performers being recorded. Indeed, the enduring popularity of conductors like Antal Dorati, Paul Paray, and Frederick Fennell and his Eastman Wind Ensemble would not be nearly as potent without the documentation of their art as taken down by Fine and her production team.

As the years have ticked by – with new technical innovations introduced and thousands of new classical records produced – the Mercury recordings have retained their reputation as examples of exceptional clarity and realism in sound. For many, these recordings remain the audiophile standard against which all other sound production quality is judged.

But the story doesn’t end there. The pioneering efforts of Ms. Fine would have an interesting “second act” more than three decades later. It was to her that Philips turned in the early 1990s to undertake the endeavor of remastering and transferring nearly the entire Mercury classical catalog to CD. And this was no mere “symbolic” or cameo effort on Fine’s part, either. The original Mercury mixing equipment would be repaired and brought back into production for the project. Ms. Fine performed the digital editing herself – nearly 50 years after she had done it (in analog) the first time around!

And again, the critics swooned.

What is the legacy of Wilma Cozart Fine? It’s not just that she was a pioneer in classical music’s Hi-Fi wave – or that she was the first woman to break into a male-dominated field. It’s that she and her team brought the world some of the best classical recordings ever made …and set a standard for excellence that has yet to be surpassed nearly six decades on.
