Do you know of any newspaper columnists who have risen to fame using a fake name?

Mr. Alice:

It is my dream to one day become a famous newspaper columnist, only, get this, I don't plan on using my real name. My reading public will know me only by my nom de plume. Do you know any newspaper columnists who have risen to fame using a fake name?

Of course, there's Ann Landers and Abigail Van Buren (the Friedman twins, Esther Pauline "Eppie" Friedman Lederer and Pauline Esther "Popo" Friedman Phillips); Silence Dogood (Benjamin Franklin); and Stick (Juan Antonio Samaranch, for his sports column on roller hockey). Lemme think...um...gee, nobody else comes right to mind, Herb, assuming that is your real name. Sorry.
