Academic philosophers were also starting to notice his work. In 1856 University of Leipzig sponsored an essay contest about Schopenhauer's philosophy, which was won by Rudolf Seydel's very critical essay. Schopenhauer's friend Jules Lunteschütz made a first of his four portraits of him—which Schopenhauer did not particularly like—that was soon sold to a wealthy landowner Carl Ferdinand Wiesike who built a house to display it. Schopenhauer seemed flattered and amused by this, and would claim that it was his first chapel. As his fame increased copies of his paintings and photographs were being sold and admirers were visiting the places where he lived and wrote his works. People visited Frankfurt's "Englischer Hof" to observe him dining. Admirers gave him gifts and asked for autographs. He complained, however, that he still felt isolated due to his not very social nature and the fact that many of his good friends already died from old age.
