In 1797, while tutoring two youths of an aristocratic family, he visited Leipzig as their escort and had a chance to attend lectures at Leipzig University, where he was fascinated by contemporary physical studies including chemistry and biology. He also visited Dresden, where he saw collections of the Elector of Saxony, to which he referred later in his thinking on art. On a personal level, this Dresden visit of six weeks from August 1797 saw Schelling meet the brothers August Wilhelm Schlegel and Karl Friedrich Schlegel and his future wife Caroline (then married to August Wilhelm), and Novalis.
