Born in Düren, Rhenish Prussia, Deuster immigrated to the United States with his parents, who settled on a farm near Milwaukee in May 1847. Deuster had pursued an academic course at a college in Düren, but left too young to graduate.
He completed his self-education in a printing office. He started a Milwaukee newspaper called the Hausfreund in 1852; it was later taken over by George Brumder's Germania Publishing. He moved to Port Washington, Wisconsin, in 1854 and edited a newspaper. He also served simultaneously as deputy postmaster, deputy clerk of the circuit court, clerk of the land office, and notary public.
He returned to Milwaukee in 1856 and edited the Milwaukee See-Bote (later Seebote), a German languageDemocratic daily paper, until 1860, when he became proprietor.
Deuster as Copperhead
The See-Bote had been founded by Archbishop John Henni as an anti-radical organ, and under Deuster's leadership it took a strong stance against German radicals and radicalism, calling Carl Schurz "a political mountebank" and railing against the new Republican Party with its freethinkers and abolitionism. During the American Civil War, Deuster was widely reviled as a prominent Copperhead, as he opposed the abolitionist influence on the Lincoln administration and defended General George B. McClellan against his critics. He encouraged negrophobia in his immigrant readers, warning that emancipation and abolitionism would lead to a "Negrocracy" as free whites were forced to compete with cheaper "black cattle," and referred to the abolitionist Milwaukee Herold as part of the "German Nigger Press". Deuster and the See-Bote were widely blamed for the November 10, 1862 anti-draft riot in nearby Port Washington. The commander of the German-majority Union Army of South-east Missouri forbade the circulation of the paper in areas under his control. Abraham Lincoln, described in the See-Bote as "the most incapable of statesmen and the most irresponsible of the butchers of men", was defended only when Deuster saw him as being harried by the more radical elements within the Republican Party. Unlike some Copperhead newspaper editors, Deuster publicly mourned Lincoln's assassination, expressing a fear that it would give free rein to the Radical Republicans and unleash a policy of "retribution and revenge".[1]
He was re-elected to the Forty-seventh Congress (17.574 votes to 15,018 for Republican former Assemblyman Casper Sanger) and Forty-eighth Congress (9,688 votes to 8,320 for Republican former Assemblyman Frederick Winkler and 1,922 for former Republican Assemblyman George B. Goodwin, "trades' assembly" candidate). Deuster was publishing The Daily Journal a part of his re-election campaign for the 48th Congress. The young Lucius W. Nieman bought an interest in the paper and took over when Deuster was successfully re-elected. Nieman grew the publication and changed its name to The Milwaukee Journal.
He again resumed his newspaper interests, publishing the Seebote and a German language weekly titled Telephone. He was appointed chairman of a commission to diminish the UmatillaIndian reservation in Oregon in 1887. He was appointed consul at Krefeld, Germany, February 19, 1896, and served until a successor was appointed October 15, 1897. In 1898, he was the Democratic nominee for Lieutenant Governor of Wisconsin, losing in a six-way race to Republican Jesse Stone with 180,038 votes, to 126,206 votes for Deuster; 8,267 votes for Populist Spencer Palmer: 7.846 votes for Prohibitionist Willis W. Cooper; 2,535 votes for Social Democratic Party of America candidate Edward P. Hassinger; and 1,543 votes for Herman C. Gauger of the Socialist Labor Party.
He died in Milwaukee December 31, 1904, and was interred in Calvary Cemetery.
There is no source to prove that he and Joseph were related to John H. Deuster, although they were all three born in Prussia, moved to Milwaukee, and became active Democratic Party politicians and legislators.
