The Americans who risked everything.

Thomas Jefferson arrived early at the statehouse. The temperature was 72.5 degrees and the horseflies weren't nearly so bad at that hour. It was a lovely room, very large, with gleaming white walls. The chairs were comfortable. Facing the single door were two brass fireplaces, but they would not be used today.

The moment the door was shut, and it was always kept locked, the room became an oven. The tall windows were shut, so that loud quarreling voices could not be heard by passersby. Small openings atop the windows allowed a slight stir of air, and also a large number of horseflies. Jefferson records that "the horseflies were dexterous in finding necks, and the silk of stockings was nothing to them." All discussing was punctuated by the slap of hands on necks.

Ben Franklin was the only really old man. Eighteen were under 40; three were in their 20s. Of the 56 almost half - 24 - were judges and lawyers. Eleven were merchants, nine were landowners and farmers, and the remaining 12 were doctors, ministers, and politicians.
