In 1893, he painted three artworks: Philosophy, Medicine and Jurisprudence, for the University of Vienna. Later came Love (1895), Music (1895) and Junius (1896). At the end of the century Klimt produced the beautiful portraits that would be one of his greatest legacies.

According to press reports, in June 2006, the portrait Adele Bloch-Bauer I was sold for US$135 millions to Ronald S. Lauder. Since that time, the painting has been on display at the Neue Galerie in New York City (at Fifth Avenue and 86th Street). This operation has made this Klimt's work the most expensive painting ever sold.
