The uniqueness of Lincoln's beard

[L Verge]

I knew that Grant had a mustache and beard, but your interesting question sent me to Google. It would appear that the Presidents during the late-Victorian and Edwardian eras were the ones who favored facial hair.

The earliest facial hair is attributed to Martin Van Buren with his mutton-chops.
Lincoln is next, followed by Grant with beard and mustache.
Hayes also sported a beard and mustache as did Garfield and Benjamin Harrison.
Arthur had no beard, but did have a mustache and sideburns; and Cleveland and Taft both had mustaches as did Teddy Roosevelt.

I even found reference to Truman sporting a goatee once while on vacation.
