Weda Kaplinsky is head of the Juilliard piano faculty. She was also a judge at this year’s Van Cliburn competition, and seven of her students were among the 35 pianists admitted to the competition. For the past several months “Kaplinsky has been the target of an anonymous, orchestrated smear campaign, consisting of harassing e-mail messages, an anonymous letter, Internet postings, ominous late-night phone calls and a threatening statement overheard last week at Bass Hall.”
