and the Rhine provinces for the purpose of investigating their juridical institutions. As the fruit of this visit, he published his treatises Betrachtungen über Öffentlichkeit und Mündigkeit der Gerechtigkeitspflege (1821) and Über die Gerichtsverfassung und das gerichtliche Verfahren Frankreichs (1825). In these he pleaded unconditionally for publicity in all legal proceedings. In his later years, he took a deep interest in the fate of the strange foundling Kaspar Hauser who had excited much attention in Europe. He was the first to publish a critical summary of the ascertained facts, under the title Kaspar Hauser, ein Beispiel eines Verbrechens am Seelenleben (1832). Feuerbach died on 29 May 1833 in Frankfurt. There is some controversy over the cause and circumstances of his death which remain largely unclear - his family as well as he himself shortly before his death believed that he had been poisoned due to his protection of and research work on Kaspar Hauser, who himself died later the same year under suspicious circumstances. Family Feuerbach had five sons, and three daughters: Joseph Anselm Feuerbach (1798–1851), Karl Wilhelm Feuerbach (1800–1834), Eduard August Feuerbach (1803-1843), Ludwig Andreas Feuerbach (1804–1872), Heinrich Friedrich Feuerbach (1806–1880), Rebecca Magdalena (1808–1891), Leonore Feuerbach (1809-1885), and Elise Feuerbach (1813–1883).
