"This last fact highlights an even more astonishing result of the exhibition. Surviving members of Unit 731 who had sworn to remain silent about their memories came out before the public to testify-to confess-and finally unburden their minds. After a half century of silence, they told. Some could tell all but their names, and retained that one secret before the public: an omission meaningful to them, but a minor exclusion for those of us more interested in their stories than in their identities. Others identified themselves openly. Some reached the point of weeping with equal openness, as they looked back through decades of silence to stir up ugly recollections. But those who are coming forward now, after some half-century of silence, are among the most forceful in pressing for the story to be told. Additionally, a limited number of members of the post-war generation- scientists, doctors, writers-are searching out the survivors, doing their own research, and informing the public through writings and lectures. Outrage and shame span the generations. Exhibition sites generally have a desk where visitors may write their impressions and comments. Attendees from elementary school on up have recorded the shock of the history lesson."
