I use single spaces between sentences, but my ancestors
used 2... who knows why? :).
Typewriters.
In typesetting, especially when doing right-margin justification,
we have "stretchy spaces" between words. The space after end-of-
sentence punctuation marks is supposed to be about 50% larger than
the width of the between-words spaces, and if the word spaces get
stretched, so should the end-of-sentence space. Note that this is
all in the variable-pitch font world.
Since typewriters are fixed-pitch, the way to emulate the
1.5-space-wide gap is to expand it to 2.
