Diogenes was born in Sinope (modern-day Sinop, Turkey), an Ionian colony on the Black Sea in 412 or 404 BCE. He is the proud founder of Cynic Philosophy and believer of cosmopolitan values and attributes. However, he was known as a controversial person who publicly mocked Alexander, embarrassed Plato, disputed his interpretation of Socrates and sabotaged his lectures.
The son of Hicesias, a banker he had to face the punishment of banishment for adulteration the currencies of the country. He was falsely embroiled in the currency scam.
He had minimal requirements for a living. He lived in a tub in between the marketplace, begging for a living, moving with a lamp to search an honest person in the market. He was known for these types of philosophical stunts which received criticism and humor.

He raised himself up and looked at the royal procession headed by Alexander. Diogenes fixed his glance upon the distinguished looking Alexander starring in his one blue and one black eye. The monarch greeted him with awesome respect and asked if he wanted any special royal favor to be granted, "Yes," said the eminent philosopher Diogenes to the Alexander, "Stand a little out of my sun."
So struck was Alexander by this reply that he moved out in silence. The emperor admired the sincere hauteur and opulence of the poor man who had nothing but disdain for him and his royal treasures.
