Stein was born Modest Aronstam in
Kovno,
Lithuania (then in the
Russian Empire), on February 22, 1871, and was nicknamed "Modska". His father, Lazar Aronstam, was a
pharmacist who moved to Kovno from
Vilna. Stein was the cousin of
Alexander Berkman (Stein's father and Berkman's mother were siblings), and attended the same
gymnasium. The two were similar both physically, being short though muscular, and politically, supporting militant
anarchism. Stein was driven to a career in art, which Lazar disapproved of, forcing Stein to sneak downstairs at night to practice drawing or painting when his parents were asleep. At the age of 17, in 1888, Stein left Russia for the United States to be able to pursue his art career; this was soon after Berkman had also left for the US. Stein arrived in
New York City on August 4, 1888, and met up with Berkman soon after arriving. (who would later marry German-American anarchist
Johann Most). They formed a
commune inspired by
Nikolai Chernyshevsky's novel
What Is to Be Done?, trying to actualize their shared ideals of
women's equality and cooperative living. While the other three worked making clothing in factories or at home, Stein continued trying to become a professional artist, occasionally selling pictures, but mostly funded by the other roommates, or by money sent by his parents in Russia. When he did sell one of his paintings, Stein would sometimes spend the money on "beautiful" luxuries, such as flowers, or fashionable clothes, which made Berkman fume. On one occasion when Stein overspent on a meal, Berkman actually struck him, calling this theft from the revolution. For the next years, the group moved their commune several times, while the members worked at different jobs. In late 1890, the three lived in
New Haven, Connecticut, with Helene and her sister Anna Minkin, while Berkman worked as a printer's apprentice, the women made dresses, while Stein continued drawing, but also tried making shirts, and his father's trade as a night clerk in a drug store, before all returned to New York. In 1891, Stein moved to
Springfield, Massachusetts, where he drew crayon portraits from photos in a photographer's shop. This was relatively successful, so he invited Goldman to take orders, and in 1892, moved to
Worcester, Massachusetts, to open the "French Art Studio", where Berkman also joined them to frame. The three continued to live together, passing Berkman and Goldman as a married couple and Stein as Goldman's brother. As their art studio gradually failed, they opened a
luncheonette based around Goldman's cooking, which was more successful. In late June 1892, the three read about the start of the
Homestead Strike, an industrial
lockout and
strike at the
Homestead Steel Works in the
Pittsburgh area town of
Homestead, Pennsylvania. They saw this as a matchless opportunity to spread their anarchist philosophy. Goldman and Berkman quickly shut down the luncheonette, left Stein behind to shut down the art studio, and returned to New York to plan with their fellow anarchists. Initially intending merely to give speeches and spread pamphlets, news of the
July 6 riverbank battle between strikers and
Pinkerton agents inspired them to more decisive action, to serve as
propaganda of the deed, namely to assassinate
Henry Clay Frick, main company representative. Berkman made some dynamite bombs, but testing showed them unreliable, so went to Pittsburgh intending to use a pistol and a knife. The dynamite was left behind in Worcester with Stein, "the twin", as a backup plan. Berkman's attempt, on July 23, failed, and he was captured, though Frick was wounded. On July 25, Stein followed to
Pittsburgh to finish the job. However a conspirator among the New York anarchists was an informer for the
Austrian consul, who informed the Pittsburgh police about the plot, which also leaked to the press in distorted form. So on his way to blow up Frick's house with pockets full of dynamite, Stein—then still called Aronstam—saw a newspaper with a headline warning against "Aaron Stamm" as a Berkman conspirator. He became frightened, dumped the explosives in an
outhouse, and returned to New York. To avoid police, Stein spent several months in
Detroit with anarchists including Robert Reitzel, where he worked with an engraving firm, but returned to the New York in the fall of 1892, when prosecutors determined they did not have enough evidence to charge either Stein or Goldman. == Artistic success ==
