No doubt, that there may have been other Irish persons that may have worked at the Scott Base, but the record books show that Mike Barry was the first Irishman to get to the South Pole manhauling his own supplies from Hercules Inlet to the South Pole in 2004.
Other notable Irish firsts include Mark Pollock, who was the first Blind person to walk to the South Pole in 2009, and Clare O'Leary, who was the first Irish woman to reach the South Pole, in 2008 when she was a member of the first all Irish team to reach the Pole.
Sir James Clark Ross was the first British person to the south pole.
The North Pole lies in the Arctic, the South Pole is in the Antarctic. So it'd be impossible to reach North Pole in Antarctic, since it isn't there.
Pole-ish. (sorry!)
The first person to reach the south pole was Roald Amudsen
Robert Falcon Scott reached the south pole 36 days after Roald Amundsen.

Roald Amundsen and his team.
The First men to reach both Poles on foot, were Charlie Burton and Ranulph Fiennes as part of the Transglobe expedition of 1979/82.
All of Amundsen's team members were Norwegian.
If you are standing precisely at the South pole, you can only travel north.
