Roman Lewis (1864–1918) was a prominent Jewish anarchist in New York.
Fluent in Russian and Yiddish, he was the first editor of the Yiddish-language anarchist newspaper Fraye Arbeter Shtime.
In New York, when he wasn't working at making shirts, he spent his leisure time with the anarchist movement and spoke at Jewish union rallies.
[3] He was elected an assistant district attorney in Chicago as a Democrat.
The police were tipped off before the attempt could be made, and Stein believed Lewis was the informant.
