Well... Dr. Robotnik comes from a VERY wealthy family. His male ancestors were once scientists as well. These "smart" genes run in the family so Ivo got his degree at a very young age by skipping many grades because of his intelligence.
In Japan, he was always called Eggman, and when it was ported to America, he was called Robotnik. Then, in Sonic Adventure, in an early cutscene, Sonic says "Look! It's a giant talking egg!" and from then on, he was called "Eggman" by Sonic and at first it was an insult, but now Robonik calls himself "Eggman".
The character of Robotnik/Eggman was created by SEGA in 1990. When the character was shipped over to the U.S along with the first Sonic game in 1991, SEGA of America decided to officially make his name Dr. Ivo Robotnik, because it sounds better. He stayed Dr. Eggman in Japan. By 1998, SEGA had decided to revert his name to Dr. Ivo "Eggman" Robotnik worldwide, for unknown reasons.
Doctor Eggman was his original name, in the Japanese version of Sonic the Hedgehog. Robotnik was his name for english-speaking countries. Yuji Naka has explained that 'Robotnik' is his real name, and Doctor Eggman is an alias that he goes by, so it's not an insulting nickname other characters have for him, it's something he himself uses, and he uses 'egg' for the names of some of his machines, such as the Death Egg and Egg Emperor.
