Galthii led his team superbly during France's Six Nations Grand Slam in 2002, an achievement that also saw France pick up the Team of the Year Award and Bernard Laporte the accolade for Coach of the Year.
South Africa centre Pat Barnard received the Under 21 player of the Year Award, in association with Waterford Crystal, whilst Luke McAlister - New Zealand's outstanding talent at fly-half - won the Under 19 award.
Commentator Bill McLaren was recognised for his outstanding services to rugby with a Chairman's Award and the Spirit of Rugby Award went to the old Christian Club Montevideo 30 years after the tragic plane crash in the Andes.
Last year, to mark the occasion, the survivors who have retained their love of the game, played the match that should have been played 30 years ago. Roberto Cannessa, who walked for 11 days in search of help, and another one of the survivors, Gustavo Zerbino, were present to receive the Award.
