Gustav Romero, a 24-year-old virtuoso from San Diego, has won the 1989 Clara Haskil Prize for young classical pianists, organizers in Vevey, Switzerland said. An international, seven-member jury chose Romero after hearing 43 competitors from some 20 countries in the 10-day event. Romero was born in San Diego and studied at the Juilliard School of Music. He has given recitals in Boston, New York and Los Angeles and appeared as a soloist with the New York Philharmonic and Los Angeles Philharmonic. The $7,500 prize was founded in 1963 in memory of Clara Haskil, a Romanian-born pianist who became famous in Paris and Vienna at the start of the century.
