In August 1961, Ginzburg managed to conduct an extensive interview of 18-year-old Bobby Fischer. Ginzburg said he got in touch with Fischer by simply giving Fischer's older sister Joan a call, and he "got along well" with Fischer. He sold the interview, entitled "Portrait of a Genius As a Young Chess Master" to "Harper's Magazine", which published it in January 1962. The interview of the reclusive chess genius became one of the most famous interviews in history, especially among chess players, and has gained great popularity ever since, partly as the first public indication of Fischer's paranoia and critical behaviours. However, Bobby Fischer himself hated the article and denied most of it, claiming that it was not even a remotely accurate representation of his actual statements or his life, while Ralph Ginzburg destroyed all of the research materials that would have backed his interview. The interview made young Fischer furious and "created a distrust of reporters", and therefore it became practically the last formal interview Fischer ever gave, which ironically added to its popularity.
