The 20th Century has had a number of personalities whose fame far exceeded their ability. Can we say that their grasp exceeded their reach? Here, in my opinion, are a fair number of them:
Architecture – Frank Lloyd Wright
Art – Andy Warhol (honorable mention, Salvador Dali)
Business – Bill Gates
Dance – Martha Graham
TV – Walter Cronkite
Movies – Mae West (honorable mention, Joan Crawford)
Music – Bob Dylan (honorable mention, Madonna)
Poetry – Maya Angelou
President – Woodrow Wilson (honorable mention, Jimmy Carter)
Royalty – Princess Diana (honorable mention, Prince Charles)
Science – Carl Sagan (honorable mention, Al Gore)
Sports – Wilt Chamberlain
Stage – Ethel Merman (honorable mention, Carol Channing)
Writing – Norman Mailer
If anyone wants my rationale(s) for these pick(s), leave a challanging comment and I will respond.
