Alexander von Humboldt was his brother. Both were friends of Goethe and Schiller, Wilhelm frequently visiting them in Weimar and maintaining a correspondence with Schiller. He was an attender at Mendelssohn’s musical salon, while Coleridge visited him in Rome. Schinkel, a friend, remodelled his home Schloss Tegel for him. Bopp was a great friend, first met when Humboldt was Prussian envoy in London; he taught Humboldt Sanskrit, and was later given a position at Berlin University, an institution founded by Humboldt. Fichte was its first rector; Humboldt attended his lectures as often as he could.
