Skull & Bones — formally the Order of Death, informally known as "The Order" or simply "Bones" — was founded at Yale University in 1832 by William Huntington Russell and Alphonso Taft (father of President William Howard Taft). Russell had spent a year studying in Germany and returned with the model of a German student fraternity, which he adapted into something more secretive and more selective than the existing Yale societies.
Each year, fifteen rising Yale seniors are "tapped" — selected for membership by the outgoing class. This number has remained almost constant since the society's founding. Members are called "Bonesmen" and refer to non-members as "Barbarians" or "vandals." The society owns a windowless building on the Yale campus known as the Tomb — a brownstone structure that has become one of the most recognisable symbols of American élite culture — and an island in the St Lawrence River called Deer Island, used for retreats.
The society's emblem — a skull and crossbones above the number 322 — is displayed on its properties and paraphernalia. The significance of 322 is debated: the most common explanation is that it refers to 322 BCE, the year of the death of the Greek orator Demosthenes, after which a particular school of rhetoric — which the society allegedly models itself on — was founded. Others interpret it as the year of the society's founding chapter within a German parent organisation. Neither explanation is definitively documented.
The society operated in near-total secrecy for most of its history. Members were forbidden from acknowledging its existence to outsiders. This began to change in the 1970s and 1980s as journalists began investigating, and accelerated in 2001 when journalist Alexandra Robbins published Secrets of the Tomb — based on interviews with dozens of current and former members — which provided the most detailed account of the society's practices yet published.
