Guillaume Henri Dufour

Guillaume Henri Dufour (French pronunciation: [ɡijom ɑ̃ʁi dyfuʁ]; 15 September 1787 – 14 July 1875) was a Swiss military officer, structural engineer and topographer.

[4][1] In 1847 the Catholic cantons of Switzerland attempted to form a separate alliance of their own, known as the Sonderbund, effectively splitting from the rest of the country.

For example, on November 13, 1847, when everything was ready for the offensive, he sent Lieutenant de Cerjat as an emissary to the authorities of the city of Fribourg enjoining them to surrender in order to avoid a deadly battle.

[5][6] With his mindful approach in the Sonderbund War, Dufour not only prevented a collapse of the Confederation through intervention by foreign powers, but he also created a basis of reconciliation that enabled the cantons to agree on a common federal state already in 1848.

His success, and the moderation with which he treated his vanquished fellow-countrymen, were acknowledged by a gift of 60,000 francs from the Federal Diet and various honours from different cities and cantons of the confederation.

[citation needed] The following year he presided over the international conference which framed the First Geneva Convention as to the treatment of the wounded in time of war.

His work included rebuilding a pumping station, quays and bridges, and he arranged the first steam boat on Lake Geneva as well as the introduction of gas streetlights.

[17][18] Numerous cities and towns in Switzerland have streets named for him: rue du Général-Dufour in Geneva, La Chaux-de-Fonds; via Gen. Henri Dufour in Chiasso; rue du Général- Dufour/General-Dufour-Strasse in Biel/Bienne; Dufourstrasse in Aarau, Basel, Bern, Biberist, Lenzburg, Luzern, Rorschach, St. Gallen, Thun, Weinfelden, Wettingen, Wil, Zollikon, Zürich; via Dufour in Lugano.

[19] The Dufourspitze (the highest mountain peak in Switzerland and second of Western Europe) in the Monte Rosa Massif is named after Dufour, to honour his cartographic achievements.
