But I have wracked my brain to remember whether Booker T. Washington ever came up in discussions that summer. I don't think so.

I'm not sure I understand. As a Freedom School teacher, you must have had some input in the classroom curriculum. Are you saying that Booker T. Washington, certainly one of the most prominent African Americans in his time, was simply overlooked? Was that deliberate? Did it reflect the political precepts of the umbrella organizations that set up the Freedom Schools? (I understand COFO was one.) Although you and SNCC may have considered him a "relic of the past", was that justification to edit him out of classroom discussion? That, to me, seems very close to neglect and suppression.

The entire curriculum and history of the Mississippi Freedom Schools is available online at Education and Democracy.

An excerpt:

Everything about the Freedom schools was fluid in order to link the reality of the students’ lives to the goal of social and economic justice for all. The teachers taught whatever was needed and requested by the students, from typing to French. They were encouraged to modify the curriculum as needed, but to stick with the question and answer method. “The paper curriculum that Alice and I had produced was for the most part set aside as teachers improvised: writing school newspapers, typing, French, and poetry were among the most popular subjects,” wrote [Staughton] Lynd later.[18] The actual experience of the Freedom Schools was created by students and teachers in active and often spontaneous collaboration. As lawyer and summer volunteer Len Holt stated:

"From the beginning, the schools were a challenge to the insistent principle that everyone had talked about so much: flexibility. Where the initial plans had been for only the tenth, eleventh, and twelfth grades, one found sitting in the informal circles youngsters with the smooth black faces and wondering eyes of the impish faces of nine and ten who were mere fifth-graders. Flexibility. And there just behind teen-aged boys—with slender, cotton-picking muscles—were sets of gnarled hands and the care-chiseled faces of grandmothers, some of whom said they thought they were in the seventies (birth records for the old are almost non-existent). Flexibility."[19]

And the University of Southern Mississippi's Digital Collection of Freedom Summer contains photographs, letters, journals, diaries and more from local citizens and freedom workers during that long, hot summer. Rather chilling (because we know what happened and at the time he didn't) is the June 26th letter from Matthew Zwerling in Clarksdale to his parents in New York where he expresses concern about his friend Andrew Goodman who had gone missing just a few days before Zwerling arrived. The bodies of Goodman, James Chaney and Michael Schwerner were found murdered in Philadelphia, MS.
