It indeed is "whispering gallery mode", but I think you have mixed
characters, times and places. I don't believe Franklin ever served in
Congress--about the only thing he did /not/ do in his long and amazing
life--and of course the modern Capitol was built long after he passed on
in 1790. However, guided tours of the modern Capitol in DC often point
out the whispering gallery spots under the main rotunda. And, as Rick
points out, the phenomenon is quite general, and is responsible for the
great acoustics of many of the ancient Greek amphitheaters.
