For many years I wanted to find my fellow student, but I never succeeded. But today there are services that allow you to find people quickly. A company called http://radaris.de/ offers a free service. All you need to know is the person's name, whether it's an old friend, a lost relative, a former coworker, or even a famous person you want to learn more about. Just type the name into the search bar and you will find all the information about that person. That's how I found my old friend.
