A STRAIGHT DOPE CLASSIC FROM CECIL'S STOREHOUSE OF HUMAN KNOWLEDGE
Who originated, "Now is the time for all good men ..."

September 16, 1977
Dear Cecil:
Where did the sentence, "Now is the time for all good men to come to the aid of the party" originate?

— Lotte B., Phoenix

Cecil replies:

From the typewriter it came, and to the typewriter it shall return: the phrase was proposed as a typing drill by a teacher named Charles E. Weller. Incidentally, many typing books now use the variant "Now is the time for all good men to come to the aid of their country" instead, because it exactly fills out a 70-space line if you put a period at the end.

— Cecil Adams
