Roman Catholic Diocese of Lausanne, Geneva and Fribourg in a papal brief of 20 September 1819, the city of Geneva and twenty parishes belonging to the old Diocese of Geneva (which in 1815 had become Swiss) to the See of Lausanne. The bishop (in 1815 Petrus Tohias Yenni) retained his residence at Fribourg, and since 1821 has borne the title and arms of the Bishops of Lausanne and Geneva. His vicar general resides at Geneva, and is always parish priest of that city. Bishop Yenni died on 8 December 1845 and was succeeded by Etienne Marilley. Deposed in 1848 by the Cantons of Berne, Geneva, Vaud and Neuchâtel,
Geneva Lake with the nearby town of Geneva, Illinois, the city was renamed "Lake Geneva"; later the lake was renamed "Geneva Lake". Lakeshore attractions include Big Foot Beach State Park, Lake Geneva Yacht Club, the George Williams College campus of Aurora University, and Yerkes Observatory. The observatory is owned by the University of Chicago, which has established a study group to plan a regional center for science education at the observatory. Public access to the lake is allowed as the result of a decision by early European settlers that "20 feet of land leading up to the shoreline should be public domain."
