An "eponym" is derived from the <em>discoverer's name </em>and it is used to name a person, place or thing, such as a<em> disease, structure, operation, procedure, etc</em>. One popular example of this is the "Hartnup disease." This is a metabolic disorder of the body which was seen in the Hartnup family of England. Around 4 members of the family carried the disease with them and were studied for it. Thus, the name was derived from their family name. Another example is the Ford Motor Company which was named after the founder, <em>Henry Ford.</em>
