Hinton Rowan Helper, from North Carolina, was a writer, abolitionist, and white supremacist. In 1857, he published a book that he dedicated to the "non-slaveholding whites" of the South. Titled The Impending Crisis of the South: How to Meet It and written partly in North Carolina but published when the author was in the Northern United States, it argued that slavery hurt the economic prospects of non-slaveholders and was an impediment to the growth of the entire region of the South. Anger over his book due to the belief he was acting as an agent of the North attempting to split Southerners along class lines led to Southern denunciations of "Helperism."
Hipparchia of Maroneia was a Cynic philosopher, and wife of Crates of Thebes. She was the sister of Metrokles, the cynic philosopher. She was born in Maroneia, but her family moved to Athens, where Hipparchia came into contact with Crates, the most famous Cynic philosopher in Greece at that time. She fell in love with him, and, despite the disapproval of her parents, she married him. She went on to live a life of Cynic poverty on the streets of Athens with her husband.
Hipparchus was a Greek astronomer, geographer, and mathematician. He is considered the founder of trigonometry, but is most famous for his incidental discovery of the precession of the equinoxes. Hipparchus was born in Nicaea, Bithynia, and probably died on the island of Rhodes, Greece. He is known to have been a working astronomer between 162 and 127 BC.
Hippasus of Metapontum was a Greek philosopher and early follower of Pythagoras. Little is known about his life or his beliefs, but he is sometimes credited with the discovery of the existence of irrational numbers. The discovery of irrational numbers is said to have been shocking to the Pythagoreans, and Hippasus is supposed to have drowned at sea, apparently as a punishment from the gods for divulging this. However, the few ancient sources which describe this story either do not mention Hippasus by name or alternatively tell that Hippasus drowned because he revealed how to construct a dodecahedron inside a sphere. The discovery of irrationality is not specifically ascribed to Hippasus by any ancient writer.
Hippias of Elis was a Greek sophist, and a contemporary of Socrates. With an assurance characteristic of the later sophists, he claimed to be regarded as an authority on all subjects, and lectured on poetry, grammar, history, politics, mathematics, and much else. Most of our knowledge of him is derived from Plato, who characterizes him as vain and arrogant.
