Ku Klux Klan

The first Ku Klux Klan, informally known as the Klan or the "Hooded Order" was created on December 24, 1865 in Pulaski, Tennessee. The name was formed by combining the Greek word Kyklos (meaning "cycle", suggesting a circle or band of brothers) with the word clan. Klan members adopted masks and robes that hid their identities and targeted through night rides black or white Rebublicans. 

James Matthew Barries

In April 1929, James Matthew Barrie, the creator of Peter Pan, gave the rights to his work to Great Ormond Street Hospital. It is a children's hospital located in the Bloomsbury area of London. The earnings were and still are used to fund the hospital and its activities.

Neptune

Neptune was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of planet Uranus led Alexis Bouvard, a French astronomer, to deduce that an eighth planet existed in the solar system. On 23 September 1846, Johann Gottfried Galle, with the assistance of student Heinrich Louis d'Arrest, was the first person to view the planet Neptune. He used the calculations of Urbain Le Verrier to know where to look.
