10 Famous People and Their Doppelgangers at the Museum

Mark Zuckerberg

Mark Zuckerberg is best known for building the internet empire that is Facebook (which makes it all the more fun to find a king as his doppelgänger). Phillip IV was king of Spain for almost half of the 17th century, and he also acted as king of Portugal as Phillip III. In this portrait by Diego Velázquez, the main painter of his court, we see the king at 18 years old (the same age as Mark Zuckerberg in his first year at Harvard).
