I personally haven't read much by him, but you can find his writings on the anarchist library. https://theanarchistlibrary.org/search?query=alexander+berkman
no one needs to read more of my gushing about Prison Memoirs, but yes to all that. It is one of my very favorite books.His dedication to anarchism and selflessness is noteworthy (even if I might be critical of the latter part at this juncture), but his humanity, flawed nature, and vulnerability are what make him really stand out.He shot and stabbed Frick multiple times but couldn't do the deed. He had a small bird as a friend while incarcerated which was murdered by the screws. When he got out, he both helped found the Ferrer School, and was the likely ring leader of another dynamite plot against Rockefeller that failed and resulted in the death of four people. Fleeing New York he threw himself into agitating against U.S. entry into World War I and in defense of a Galleanist bombing in San Francisco. When he decided to kill himself, he again managed to not do a good job of it and ended up dying a horrible death.If ever an anarchist really meant well and continually failed to achieve his expectations, it is Berkman, and frankly, I find a lot of resonance in that.
