There's no place like Paris when it comes to launching a fragrance empire. In 1828, Pierre Guerlain opened a small boutique to sell his own perfume blends. High society ladies flocked to the store and within a few decades Guerlain had become the favorite perfumer of courts all over Europe. Over the years, his company has grown to legendary status, and now spans makeup, body, and skincare products. Today, it's under the stewardship of famed perfumer Thierry Wasser.
