Gilbert Kaplan

Kaplan was born at French Hospital in New York City on March 3, 1941, and grew up in Lawrence on Long Island. He studied at Duke University, and earned a bachelor's degree from The New School for Social Research. He later studied at New York University School of Law. In 1963, Kaplan took a job as an economist with the American Stock Exchange, at a salary of $15,000 per year. Kaplan founded the magazine Institutional Investor in 1967. He was publisher of the magazine until 1990, and editor-in-chief for two more years, although he sold it in 1984. The New York Times reported: "The price was never disclosed but was rumored to be about $75 million." Kaplan's interest in Mahler's Symphony No 2 dated back to 1965. In 1981, he began tutelage in conducting with Charles Zachary Bornstein. He rented Avery Fisher Hall in New York for his public conducting debut in 1982, leading the American Symphony and the Westminster Symphonic Choir. Originally, the orchestra had requested that no reviews be published, but Leighton Kerner of The Village Voice breached this requested embargo with a positive review of this performance. Subsequently, Kaplan conducted Mahler's Symphony No 2 in over 100 live performances over the remainder of his life. He established the Kaplan Foundation, dedicated to scholarship and the promotion of the music of Gustav Mahler. After personal research, he twice recorded Mahler's Second Symphony: with the London Symphony Orchestra in 1987, and with the Vienna Philharmonic in 2002. Mahler's Second Symphony was the only complete work he conducted in public, although he did separately record the Adagietto from Mahler's Symphony No. 5 in a studio recording. Kaplan owned the autograph manuscript of Mahler's score of his Second Symphony and published a facsimile edition of the score in 1986. Tim Page wrote in The New York Times: "Only now will musicians, scholars and the general public be able to own a facsimile manuscript of one of the composer's symphonies." On 29 November 2016, the manuscript was sold at auction for £4,546,250, a record for any music manuscript at the time. He also owned one of Mahler's batons and the autograph manuscript of Mahler's song, "Ich bin der Welt abhanden gekommen", part of the Rückert-Lieder. A facsimile of this manuscript was published by the Kaplan Foundation in 2015. Both manuscripts were, at one time, on deposit at the Morgan Library & Museum in New York City. He was co-editor of the new critical edition of the Second Symphony as part of the Complete Critical Edition of Mahler's works. Kaplan's conducting attracted criticism and praise, most controversially at his December 2008 New York Philharmonic performance. Steve Smith wrote in The New York Times of this concert: David Finlayson, a trombonist of the New York Philharmonic who performed at this concert, offered a different perspective: In Kaplan's conducting engagements of Mahler's Symphony No 2, he did not accept a fee. Kaplan hosted on WNYC and WQXR for more than decade the show Mad About Music until 2012 where he interviewed famous people about their love for music. He was also on the board of WNYC trustees, and in 2000 became an Evening Division faculty member at the Juilliard School.

Kaplan set up The Kaplan Foundation in New York City which is dedicated to the scholarship and preservation of the music of Gustav Mahler. The Kaplan Foundation has published facsimile editions of Mahler's autograph manuscript of the Second Symphony, the Adagietto movement of the Fifth Symphony and the song, "Ich bin der Welt abhanden gekommen". It has produced Mahler Plays Mahler, a recording using piano rolls that Mahler made of his own compositions. These rolls are the only documents that exist of Mahler as a performer. The foundation has also published Mahler Discography (together with editor Péter Fülöp), a definitive guide to 2,774 recordings of Mahler's music; Mahler's Concerts, by Knud Martner, a compilation of the 323 known performances led by Mahler as a conductor or pianist; and The Mahler Album (editor Gilbert Kaplan), an illustrated biography containing all known photographs and a selection of drawings and sculptures of the composer. Together with Universal Edition, the foundation is co-publisher of two scores of Mahler's Second Symphony: the New Critical Edition (editors Renate Stark-Voit and Gilbert Kaplan) and the Arrangement for Small Orchestra (by Gilbert Kaplan and Rob Mathes); and with C. F. Peters, co-publisher of the New Critical Edition of Mahler's Sixth Symphony.

Kaplan was the younger brother of Joseph Brooks, an Academy Award-winning composer. Kaplan married Lena Biörck, a Swedish interior designer and daughter of Gunnar Biörck, personal physician for the Swedish Royal family, in 1970. The couple had four children. Kaplan died in Manhattan, aged 74, of cancer.
