Stewart Pollens was born in New York in 1949 and trained as a violin and keyboard-instrument maker. In the 1970s he apprenticed with harpsichord builder John Challis and studied violin-making with Mittenwald faculty at the University of New Hampshire. From 1976 to 2006 he served as the Conservator of Musical Instruments at the Metropolitan Museum of Art in New York. His work there included the restoration and maintenance of the museum's encyclopedic collection of over 5,000 instruments, as well as research, writing, and lecturing on the collection.^[2]

After leaving the Metropolitan Museum, Pollens formed Violin Advisor, LLC, a consulting firm that authenticates and evaluates fine violins.^[3] In addition to his work there, Pollens restores stringed and early keyboard instruments for private collectors and museums (including an early New York piano for the Merchant's House Museum, an English bentside spinet for the Van Cortland House, and a Viennese fortepiano for the Morris-Jumel Mansion). He has done keyboard restoration and recording preparation work for Leonard Bernstein, Paul Badura-Skoda, John Browning, Mieczyslaw Horszowski, Byron Janis, Igor Kipnis, and many others. Among the more unusual instruments that he has restored are an accordion once owned by Alice "In Wonderland" P. Liddell and a tambourine painted by Toulouse-Lautrec. ^[4]

Pollens is a contributor to The New Grove Dictionary of Music and Musicians and The Strad.

Pollens is married to the concert violinist Stephanie Chase.

Pollens's research findings include the source of the design for the decorative inlay of Stradivari 's "Greffuhle" violin ^[5] and a chemical analysis of Stradivari's violin varnish.^[6] In 1999, Pollens challenged the authenticity of the world's most famous violin, the Ashmolean Museum's Messiah Stradivarius, in a series of articles published in the Journal of the Violin Society of America. The controversy initiated by these articles and presentations at the Violin Society of America and the American Federation of Violin Makers was widely reported.^[7]
