McNamara, James B. (James Barnabas), 1882-1941

James B. NcNamara and his brother were tried and convicted of bombing the Los Angeles Times Building. James H. Maurer was president of the Pennsylvania Federation of Labor. A.J. Muste was chairman faculty at Brookwood, Inc., Katonah, N.Y.

John J. and James B. McNamara were labor activists in the early 20th century. They were from the neighborhood of Cumminsville (Northside) in Cincinnati, Ohio. They gained notoriety for bombing the Los Angeles Times Building in 1910, which killed twenty-one people and injured many more.

John J. was active in labor unions and served as the secretary-treasurer of the International Association of Bridge and Structural Iron Workers (known today as the International Association of Bridge, Structural and Ornamental Iron Workers). Between 1908 and 1911, the Iron Workers allegedly carried out 70 dynamite attacks on non-union businesses. Although these were not done with the intention of killing anyone, they were certainly meant to intimidate bosses who had resisted organization campaigns by the Iron Workers. Under John J. and other union leaders' supervision, James B. began carrying out many of the bombings. On May 9, 1909, James perpetrated his first attack on a new bridge that was being built over the Ohio River in Cincinnati.

The bombing of the Los Angeles Times Building occurred on October 1, 1910. The owner of the LA Times, Harrison Gray Otis, was a vehement anti-unionist, and used the paper to espouse his views. His paper thus became a target for the McNamara brothers. James B. planted the dynamite in an area outside the building known as "Ink Alley." A fire resulted due to the natural gas lines located beneath the bombing site, and the barrels of ink ignited.

Members of the labor movement were shocked when the McNamara brothers were accused in the bombing. Samuel Gompers hired Clarence Darrow to defend the brothers. The trial began on October 11, 1911, but it quickly became apparent to the defense that there was too much evidence against the brothers. The brothers agreed to plead guilty. John J. served 15 years in prison. John B. served a life sentence.

The brothers were sent to San Quentin following the trial. James B. continued to stay in touch with his family, Clarence and Ruby Darrow, Lincoln Steffens, and many others during his time there. He also maintained his interest in leftist politics, and took pictures of prison life at San Quentin. Both brothers died in 1941, thirty years after their sentencing. James died March 8, and John died on May 9.
