Madhouse at the End of the Earth tells the extraordinary story of the disastrous 1897–1899 Belgian Antarctic Expedition, delving into what happens when 18 men become trapped for a year on Earth's most hostile continent.

On March 5, 1898, the RV Belgica research ship became stuck in a desolate ice pack stretching beyond the horizon.

The ship's crew had no choice but to try to survive an entire winter stuck in the Antarctic — something nobody had ever done before.

Julian Sancton is an author and journalist, whose work has appeared in Vanity Fair, The New Yorker, and Wired, among others.

Sancton became fascinated by the Belgica after reading about it in a New Yorker article and found himself particularly drawn to its crew — undisciplined and poorly assembled by a man with little idea of the hardships involved in a never-before-attempted polar expedition.

Sancton's 2021 book explores the effects the Belgica's journey had on its survivors, with some inspired to lead a lifetime of polar exploration and others consigned to mental institutions.
