In Cauchy's 1823 course on the calculus, he proves the second statement
but does not even state it as a theorem; it seems to be treated just as a
convenient property of integrals. See pages 151 and 152 of Oeuvres
compeltes d'Augustin Cauchy, 2nd series, volume IV (which is available
online at gallica.bnf.fr).

In a quick search, I couldn't find any occurrences in gallica of "theoreme
fondamental"  pointing to FTC. (There are lots of other "fundamental
theorems", of course, including the one that says that the complex numbers
are algebraically closed.)
