of the Helvetic Republic. It is therefore the first capital of a unified Switzerland. Parliament met in the city hall. On 20 September, the capital was moved to Lucerne. Aarau as canton capital In 1803, Napoleon ordered the fusion of the cantons of Aargau, Baden and Fricktal. Aarau was declared the capital of the new, enlarged canton of Aargau. In 1820 the city wall was torn down, with the exception of the individual towers and gates, and the defensive ditches were filled in. The wooden bridge, dating from the Middle Ages, across the Aare was destroyed by floods three times in thirty years, and was replaced with a steel suspension bridge in 1851. This was replaced by a concrete bridge in 1952. The city was linked up to the Swiss Central Railway in 1856. The textile industry in Aarau broke down in about 1850 because of the protectionist tariff policies of neighboring states. Other industries had developed by that time to replace it, including the production of mathematical instruments, shoes and cement. Beginning in 1900, numerous electrical enterprises developed. By the 1960s, more citizens worked in service industries or for the canton-level government than in manufacturing. During the 1980s many of the industries left Aarau completely. In 1802 the Canton School was established; it was the first non-parochial high school in Switzerland. It developed a good reputation, and was home to Nobel Prize winners Albert Einstein, Paul Karrer, and Werner Arber, as well as several Swiss politicians and authors. The purchase of a manuscript collection in 1803 laid the foundation for what would become the Cantonal Library, which contains a Bible annotated by Huldrych Zwingli, along with the manuscripts and incunabula. More newspapers developed in the city, maintaining the revolutionary atmosphere of Aarau. Beginning in 1820, Aarau has been a refuge for political refugees. The urban educational and cultural opportunities of Aarau were extended through numerous new institutions. A Theatre and Concert Hall was constructed in 1883, which was renovated and expanded in 1995–96. The Aargau Nature Museum opened in 1922. A former cloth warehouse was converted into a small theatre in 1974, and the alternative culture center KIFF (Culture in the fodder factory) was established in a former animal fodder factory. Origin of the name The earliest use of the place name was in 1248 (in the form Arowe), and probably referred to the settlement in the area before
