The Heroic Age in Antarctica dates from 1899-1922 when the first men to winter over and conduct scientific research and exploration endured many hardships with some deaths.  Besides providing the first scientific studies, photography and even poetry emerged from this period. It also can be defined by the isolation of the men involved, with no outside contact or chance of rescue if things went wrong.  Here, I review some of these early expeditions including the first winter over in sea ice with the ship Beligica from Belgium, the first winter over on the continent by Carsten Borchgrevink, and the first attempt at reaching the South Pole by Robert Falcon Scott and Ernest Shackleton.
