From COMM 455 Student Michael Lotman:

“A less trumpeted but important decision was to retain Judson Welliver, a former newspaperman who worked for Harding as “literary clerk.”  In effect, Welliver served as a White House publicity man and the first dedicated presidential speechwriter.  (It was Welliver who coined the phrase “Founding Fathers,” though Harding often received the credit.)  Under Coolidge, Welliver earned a handsome salary of $7,500, equal to that of senior aides.  Although Coolidge worked hard on his own speeches and wrote far more of them than had Harding, Welliver learned to ape the new president’s style as ably as he had mimicked his predecessor’s.  Indeed, said H.L. Mencken, (right) he made Coolidge’s style “simpler and clearer,” though he added, “It continued to be, in essence, a device for flabbergasting newspaper editorial writers without actually saying anything…to roar like a hurricane without letting loose any comprising ideas.”
