Arthur E. Reimer
Early years 
Arthur Reimer was born January 15, 1882 in Boston, Massachusetts, the son of a machinist. Reimer attended public school in Boston before going on to Northeastern University, also in Boston, where he earned a law degree in 1912.
Reimer worked as a ladies' tailor in his younger years.
Political career 
In 1905, he was among those SLP members who joined the new Industrial Workers of the World (IWW). Reimer exited that organization along with his party comrades in 1908 to establish a rival organization, the Workers International Industrial Union (WIIU) as a result of disagreement between the IWW majority and the SLP group over matters of strategy and tactics.
He was the Socialist Labor Party Presidential candidate for the 1912 election. His running mate was August Gillhaus of New York, the SLP's candidate for President in the previous election, that of 1908.
Afforded access to one of the country's leading weekly news magazines of the day in the days before the election, Riemer criticized the attempt of the rival Socialist Party of America to win piecemeal ameliorative reform and declared a need for revolutionary change:
"Where the social system starts with the private ownership of the necessaries for production, the bolt that, at first, slightly impedes fatedly becomes in the end a total bar to 'opportunity' — so far as the masses are concerned. The chains of wage slavery become more galling... At such a stage of capitalist rotten-ripeness, to look for reformatory redress in the governmental and economic maxims that rocked the cradle of the green infancy of capitalism is to be blind to economic evolution. It is to seek to hold back a runaway horse by the tail....
"Capitalism has organized the forces for and firmly sunk the piers on which to rear the structure of the industrial republic — the social system under which the plants of production are owned collectively and democratically administered. * * *
"Socialism may be summed up in the motto, 'Down with the political state, up with the industrial administration!' ...Afraid, on the one hand, to alienate the vote of the 'furtive Socialists' by a propaganda which these may mistake for anarchism, the Socialist Party suppresses this vital revolutionary feature of socialism; on the other hand, afraid to forfeit the vote of floating, hence anarchistically tainted discontent, the Socialist Party has elected a notorious anarchist [ William D. Haywood ] to its National Executive Committee."
Reimer and Gillhaus received 33,070 votes in the 1912 campaign.
During the 1916 campaign, Reimer and Harrison toured the country steadily in support of their party, with Reimer thrown in jail for a time by the authorities of the mining town of Butte, Montana for pushing his radical message, while his running mate Harrison suffered a similar fate in the steel city of Homestead, Pennsylvania. During the course of the 1916 campaign, the SLP produced and distributed 1.5 million leaflets in support of the socialist cause, en route to garnering 14,398 votes.
Later years 
The Russian Revolution of 1917 exerted an enormous impact upon the membership of the Socialist Labor Party, as with all on the political left wing in America. A significant section of the SLP exited the party in the 1917-1919 period to join forces with the communist movement in the United States. According to one history, Arthur Reimer was among this group, joining his 1916 Vice Presidential running mate, Caleb Harrison, Buffalo, New York druggist and party veteran Boris Reinstein, the late Daniel DeLeon's son, Solon DeLeon, and Dr. Julius Hammer of New York City. Another source, published in 1925 and edited by Solon DeLeon himself, contends that Reimer had not left the embrace of the SLP up to that date.
