Gilbert Kaplan was an American conductor whose late-blooming musical career was almost entirely devoted to performances of Gustav Mahler's Symphony No. 2 in C minor, "Resurrection." A businessman by profession, he was the founder and publisher of the magazine Institutional Investor, which he edited until 1993. He also established the Kaplan Foundation, which is involved in research for a critical edition of Mahler's Second Symphony. Kaplan made his first appearance as a conductor in 1982. His performances of the Second yielded recordings with the London Symphony Orchestra and the Vienna Philharmonic Orchestra, as well as appearances with the Melbourne Symphony Orchestra and the New York Philharmonic. With Rob Mathes, he arranged the Second Symphony for small orchestra, calling for approximately half the forces Mahler required, and this reduced version was recorded by Kaplan with the Vienna Chamber Orchestra on Avie.
