Albert Richard Parsons was a pioneering American socialist and later anarchist newspaper editor, orator, and labor activist. As a teenager, he served in the military force of the Confederate States of America in Texas, during the American Civil War. After the war, he settled in Texas, and became an activist for the rights of former slaves, and later a Republican official during Reconstruction. With his wife Lucy Parsons, he then moved to Chicago in 1873 and worked in newspapers. There he became interested in the rights of workers. In 1884, he began editing The Alarm newspaper. Parsons was one of four Chicago radical leaders controversially convicted of conspiracy and hanged following a bomb attack on police remembered as the Haymarket affair.

Lucy E. Parsons was an American social anarchist and later anarcho-communist. Her early life is shrouded in mystery: she herself said she was of mixed Mexican and Native American ancestry; historians believe she was born to an African American slave, possibly in Virginia, then married a black freedman in Texas. In addition to Parsons, she went by different surnames during her life including Carter, Diaz, Gonzalez and Hull. She met Albert Parsons in Waco, Texas, and claimed to have married him although no records have been found. They moved to Chicago together around 1873 and Parsons' politics were shaped by the harsh repression of the Chicago railroad strike of 1877. She argued for labor organization and class struggle, writing polemical texts and speaking publicly at events. She joined the International Workingmen's Association and later the Knights of Labor, and she set up the Chicago Working Women's Union with her friend Lizzie Swank and other women.
