Tony Stark: Genius. Billionaire. Playboy. Philanthropist.
Bob is a Gadgeteer Genius. He then gets a great idea for an invention; maybe a Time Machine, a cloning machine, or a doomsday weapon. After he designs any of those things, he catches the attention of a government official, the president, or a king. This powerful person wants to buy this thing for a trillion dollars! This inventor becomes the richest man in the world after selling so many inventions!
Bob now owns a mansion, a yacht, a private jet, his own island, and is now the owner of the Mega-Corp. This person is one of the smartest and the richest people in the world, maybe even the universe! Anyone who wants to make loads of dough might be a person who seeks knowledge.
This would take a person from Rags to Riches if they start out as poor and homeless.

- Tintin: Professor Calculus is at first presented as a Bungling Inventor and Omnidisciplinary Scientist, but he clearly manages to have enough money to fund his inventions (and is one of the lead scientists in a working space program at one point). At the end of "The Treasure of Rackham the Red", the titular treasure has not been found (only some old parchments were), so Professor Calculus jumps in to save the day, telling him that the government bought his shark submarine design and that he'll happily help Haddock buy the castle mentioned in the parchments (as it was on Haddock's expedition that the sub proved its worth). And when they visit, Haddock and Tintin find the treasure which was in the castle all along.

- Esmond Roseburrow from the Dishonored series invented the modern whale oil tech, kickstarting a One-Man Industrial Revolution, and became rich and famous off his patents.
