Thus, whatever may be thought of Napoleon's ultimate aims, it was owing to him that Switzerland enjoyed quiet, prosperity, and perfect self-government at a time when Europe generally was torn by quarrels and steeped in war. The Swiss people gave their whole attention to home affairs, and to the striving after intellectual and material progress, as they had done in the Helvetic days, but now with more success. Benevolent societies were founded, high schools established, and institutions for the advancement of letters, science, and art, sprang up. Many men of note mightily stirred the ideal side of life; amongst them we may mention the novelist, Zschokke,[96] of Aargau; Martin Usteri, the poet-artist; and George Nägeli, the Sängervater, or "Father of Song." Both these latter were of Zurich, and Nägeli gave a great impulse to the founding of musical societies, and did much to spread the art of singing so common in the German districts, and especially cultivated at Basel and Zurich. Pestalozzi established a new school at Yverdon in Vaud; and his friend and former pupil, Von Fellenberg, of Bern, the superior of his master in practical management, founded his famous institution at Hofwil. This comprised a whole series of schools, high schools, schools for the middle class, agricultural schools, and elementary schools for the poor. Pater Girard, a friend of Pestalozzi, at Freiburg, did for the Catholics much what these men did for the Protestants. Another noble and devoted man was Escher, who, though of aristocratic birth himself, was yet an ardent worker for the benefit of the poorer classes. His chief work was the canalization of the Linth between Walensee and the Lake of Zurich, by means of which some twenty-eight thousand acres of unhealthy swamp became valuable agricultural land. For this labour of love, to which he sacrificed his health, the Diet decreed to him and his family the honourable addition of "Von der Linth."[97] The introduction of machinery gave a great impetus to trade and industry. In 1800 the cloisters of St. Gall were turned into the first Swiss spinning mill, and during the following decade four more mills were started in the canton. In 1808 Heinrich Kunz, the "King of spinners on the Continent," laid the foundations (Zurich) of the first of his numerous mills. In 1812 the great firm of Rieter and Co., whose machines soon gained a world-wide reputation, started business at Winterthur.
