In late October 1860, at the tail end of the crucial 1860 presidential election, Grace Bedell offered sage advice to then Congressman Lincoln on how to win the presidency. In a letter to Lincoln she suggested that, with such a thin face, he would be better off "letting his whiskers grow". This way he would be guaranteed to win the votes of her 4 brothers and would inspire American women to convince their husbands to vote for him (1860s American women couldn't vote, but they loved beards).
Later, in February 1861, President-Elect Lincoln visited Bedell during his inaugural trip from Illinois to the White House to show off his beard. Bedell contacted Lincoln again in 1864, asking for a job in the Treasury Department to support her family that had fallen on hard times. It's not known if Lincoln ever read or responded to this one, though. Her original letter has since become a piece of folk legend. Both of her letters, as well as Lincoln's 1860 letter in response have been copied and can be read at the
Grace Bedell Foundation's website.
