Johann Caspar (also Kaspar) Bluntschli (7 March 1808 – 21 October 1881) was a Swiss jurist and politician.
Biography
He was born in Zürich to a soap and candle manufacturer. From school he passed into the Politische Institut (a seminary of law and political science) in his native town, and proceeding thence to the universities of Berlin and Bonn, took the degree of doctor juris in the latter in 1829.
Returning to Zürich in 1830, he threw himself with ardour into the political strife which was at the time unsettling all the cantons of the Confederation, and in this year published Über die Verfassung der Stadt Zürich (On the Constitution of the City of Zürich). This was followed by Das Volk und der Souverän (1830), a work in which, while pleading for constitutional government, he showed his bitter repugnance of the growing Swiss radicalism. Elected in 1837 a member of the Great Council (), he became the champion of the moderate conservative party.

Upon resettling in Germany, Bluntschli's stance became more liberal and he elaborated an ethical Hegelian theory of the state which was highly influential among both German and American liberals. At Munich he devoted himself with energy to the special work of his chair, and published Allgemeines Staatsrecht (1851–1852); Lehre vom modernen Staat (1875–1876); and, in conjunction with Karl Ludwig Theodor Brater (1819–1869), Deutsches Staatswörterbuch (11 vols, 1857–1870; abridged by Edgar Loening in 3 vols., 1869–1875). Meanwhile, he had assiduously worked at his code for the canton of Zürich, Privatrechtliches Gesetzbuch für den Kanton Zürich (1854–1856), a work which was much praised at the time, and which, particularly the section devoted to contracts, served as a model for codes both in Switzerland and other countries. and in 1865 published a public letter against Pope Pius IX's apostolic exhortation Multiplices inter. In his new home, Baden, he devoted his energies and political influence, during the Austro-Prussian War of 1866, towards keeping the country neutral. From this time Bluntschli became active in the field of international law, and his fame as a jurist belongs rather to this province than to that of constitutional law. His Das moderne Kriegsrecht (1866); Das moderne Völkerrecht der zivilisierten Staaten, als Rechtsbuch dargestellt (1868), and Das Beuterecht im Krieg (1878) are likely to remain invaluable text-books in this branch of the science of jurisprudence. He also wrote a pamphlet on the Alabama case.
Bluntschli was one of the founders, at Ghent in 1873, of the Institute of International Law, and was the representative of the German emperor at the conference on the international laws of war at Brussels. He corresponded with the younger Gustave Rolin-Jaequemyns and Gustave Moynier about matters pertaining to International Humanitarian Law and the Red Cross. During the latter years of his life he took a lively interest in the Protestantenverein, a society formed to combat reactionary and ultramontane views of theology.
He died suddenly at Karlsruhe on October 21, 1881. His library was acquired by Johns Hopkins University.
