Ambrose Burnside was an American soldier, railroad executive, inventor, industrialist, politician from Rhode Island, and a Union Army general. More importantly, the sideburn is named after him. Pretty impressive stuff here. Thank you to Elizabeth for submitting this steesh.

Reason I like this picture:
The way his facial hair travels up his face and blends into his horse shoe, it appears as if his mustache has taken over his head.

Reason I don’t like this picture: 
Every picture taken before 1900 is creepy.  It’s impossible for one to look normal. These people had to sit still for minutes at a time or they would ruin the picture. Also, he’s probably not wearing pants, and there’s no way to prove otherwise.
