Luigi Galleani ( ; August 12 , 1861 – November 4 , 1931 ) was an Italian anarchist active in the United States from 1901 to 1919 . He is best known for his enthusiastic advocacy of " propaganda of the deed " , i.e. the use of violence to eliminate those he viewed as tyrants and oppressors and to act as a catalyst to the overthrow of existing government institutions . From 1914 to 1932 , Galleani 's followers in the United States ( known as '' i Galleanisti '' ) , carried out a series of bombings and assassination attempts against institutions and persons they viewed as class enemies . After Galleani was deported from the United States to Italy in June 1919 , his colleagues are alleged to have carried out the Wall Street bombing of 1920 , which resulted in the deaths of 38 people
