Berger was credited by trade union leader
Eugene V. Debs for having won him over to the cause of socialism. Jailed for six months for violating a federal anti-strike
injunction in the 1894 strike of the
American Railway Union, Debs turned to reading: Books and pamphlets and letters from socialists came by every mail and I began to read and think and dissect the anatomy of the system in which workingmen, however organized, could be shattered and battered and splintered on a single stroke [...] It was at this time, when the first glimmerings of socialism were beginning to penetrate, that Victor L. Berger — and I have loved him ever since — came to Woodstock [prison], as if a providential instrument, and delivered the first impassioned message of socialism I had ever heard — the very first to set the wires humming in my system. As a souvenir of that visit there is in my library a volume of
Capital by
Karl Marx, inscribed with the compliments of Victor L. Berger, which I cherish as a token of priceless value. In 1896, Berger was a delegate to the
People's Party Convention in
St. Louis. , 1900 Berger was a founding member of the
Social Democracy of America in 1897 and led the split of the "political action" faction of that organization to form the
Social Democratic Party of America (SDP) in 1898. He was a member of the governing National Executive Committee of the SDP for its entire duration. Berger was a founder of the
Socialist Party of America in 1901 and played a critical role in the negotiations with an east coast dissident faction of the
Socialist Labor Party in the establishment of this new political party. Berger was regarded as one of the party's leading
revisionist Marxists, an advocate of the
trade union-oriented and incremental politics of
Eduard Bernstein. He advocated the use of
electoral politics to implement reforms and thus gradually build a collectivist society. Relative to other contemporary socialist politicians, Berger was a racial conservative. He regularly fought
Eugene V. Debs on the subject. Berger initially believed
Asian immigrants would out-reproduce
white Americans and further complicate the
socialist movement's cross-racial
solidarity. Between 1907 and 1912, he masterminded racially-discriminatory
immigration restrictions in the Socialist
Party platform. However, by 1924, he opposed bans on immigration from Asia. His views on
Jim Crow were only slightly more nuanced: while Berger wrote in a 1902 editorial that "There can be no doubt that the
negroes and
mulattoes constitute a lower race — that the
Caucasian and even the
Mongolian have the start on them in civilization by many years," he does not appear to have believed that this justified "the barbarous behavior of American whites towards the
negroes". By the 1920s, Berger had reversed his views on race, stating that a man "cannot belong to a society organized to persecute Catholics, Jews, Negroes and foreigners — and at the same time call himself a Socialist." Berger was a man of the written word and back room negotiation, not a notable public speaker. He retained a heavy
Austrian accent and had a voice which did not project well. As a rule he did not accept outdoor speaking engagements and was a poor campaigner, preferring one-on-one relationships to mass oratory. Berger was, however, a newspaper editorialist
par excellence. Throughout his life he published and edited a number of different papers, including the German language
Vorwärts! ("Forward") (1892-1911), the
Social-Democratic Herald (1901-1913), and the
Milwaukee Leader (1911-1929). ==First term in Congress==
