Who said " Now is the time for all good men, to come to the aid of their country"

This originated in the U.S. in 1867 as a practice exercise for aspiring typists in Weller's Typing test.

A variant is "....come to the aid of their party."

Later on people used different phrases to gain typing speed. Some said "Now is the time to come to the aid of their party." Others used "The quick brown fox jumped over the lazy dogs," which made more sense to me because it contains all the letters of the alphabet.
The phrase was proposed as a typing drill by a teacher named Charles E. Weller, because it exactly fills out a 70-space line if you put a period at the end.
Incidentally, there are so many variant of that sentence as follow:

Now is the time for all good men to come to the aid of their country
Now is the time for all good men to come to the aid of their countrymen, blah blah blah...
Now America's elites must come to the aid of their country
Now is the time for all good men to come to the aid of this country in it's hour of need.
Now Is The Time For All Good Men [and Women] To Come To The Aid Of Our Country
