For Bayard Rustin, another of the magazine's editors, the magazine was a major commitment of time and energy, raising money and meeting every week with Muste. He wrote to Martin Luther King, who later wrote for the magazine. The June, 1963 issue contained the first full publication of "Letter from Birmingham Jail" and the first version with that title. Dellinger, Muste and Rustin were, to greater or lesser extent, all Quakers.
The New Left
Dave Dellinger graduated from Yale and then served time in prison for refusing to register for the draft in World War II. He was subsequently arrested numerous times for pacifist demonstrations. Dellinger was a leading figure in the movement against the war in Vietnam. At the age of 54 he was the oldest member of the Chicago Eight, the group that was indicted on federal charges of conspiracy and incitement to riot at the Democratic convention in August 1968. His autobiography is entitled From Yale to Jail: The Life Story of a Moral Dissenter (Pantheon, 1993).
