Who is the most anonymous President of the United States?

[Lincoln Republican]

Who is the most anonymous, or least known, or least remembered, President of the United States?

Please discuss.

[The Govanah Jake]

Chester Arthur. I admit this is the one president I have trouble remembering when listing presidents. I may also put Garfield here but is a little more well known with his assisination and all. Same with William Henry Harrison too. John Tyler and Franklin Pierce are Honorable mentions.

[Bismarck]

Chester Arthur, Franklin Pierce, or Millard Filmore.

I remember a sitcom from the '80's when two brothers were playing the home version of the $100,000 Pyramid.

"He was President?!!"  "Millard Fillmore"
"The Father of Our Country"  "George Washington"
"He could not tell a lie."  "Abraham Lincoln"
"He could not tell the truth."  "Richard Nixon"
"He smiles too much."  "Jimmy Carter"
"He smiles too much, and he's old."  "Ronald Reagan"

In a poll the fewest people were able to name Arthur and Pierce with 7% of the public each.

[Rookie Yinzer]

Franklin Pierce.

I never hear much about the presidents in between Hayes and McKinley.

[Yank2133]

Pretty much the presidents between 8-15.

[Kleine Scheiße]

Benjamin Harrison is likely the most obscure answer to this question.
