[2] He supported the ideals of the French Revolution in his youth, and attended radical meetings, such as those of the Reform League, participating in the Hyde Park riot of 1867.
[5] In 1879, he set up a printing shop on Boundary Street in Shoreditch, and began putting out propaganda, particularly focusing on supporting rent strikes.
In 1881, he was sentenced to hard labour for publishing an article calling for assassinations of rulers; Kitz then took over the editorship for a short time.
This was closed by police in 1882, by which time the two had founded the Labour Emancipation League (LEL), a libertarian socialist organisation, which merged into the Social Democratic Federation two years later.
[4] Kitz maintained a low profile for the next twenty years, working full-time as a dyer, although he remained supportive of anarchism.
In 1909, he began public speaking on anarchist matters again, and wrote his memoirs, published by Freedom in a series entitled "Recollections and Reflections".
