Emilie du Chatelet (1706-1749)

If this lady was alive today, you would want to be her best friend. She was a physics and mathematics genius most famous for popularizing Newton's work in continental Europe, as well as laying the groundwork for Einstein's famous E=mc2 equation. She was also gorgeous, hilarious, and mischievous. Kind of like an 18th Century Tina Fey. She had a long love affair with Voltaire; and we feel they are a real contender for history's cutest couple.
