Here, directly from Bob Bemer:

"So some folks started thinking about 7-bit characters,
but this was ridiculous.  ... It seemed reasonable to
make a universal 8-bit character set, ... That was a
little too much progress when presented to the standards
group that was to formalize ASCII, so they stopped short
for the moment with a 7-bit set, or else an 8-bit set
with the upper half left for future work."

Also,

"... Dr. Werner Buchholz, the man who DID coin the term
'byte' for an 8-bit grouping."

Conclusions:
1) a "byte" was defined to be exactly 8-bits
2) Bob Bemer defined a 8-bit character set
3) ASCII is not exclusively a 7-bit set
