About Ken Arthurson
Kenneth Richard "Arko" Arthurson AM is an Australian rugby league football identity. Affectionately known as "The Godfather of Manly", he played, coached and was later an administrator at the Manly-Warringah Sea Eagles club in the New South Wales Rugby League premiership. Later he ran the NSWRL, and then the Australian Rugby League during the 1990s' Super League war, resigning in 1997 as part of the peace process for creating the unified National Rugby League. Unfortunately for Arthurson and Manly, both Grand Finals were played against a St George side in the early years of their record run of 11 straight premierships. Arko played at half-back in Manly-Warringah's first Grand Final appearance in the 1951 NSWRFL Grand Final against the South Sydney Rabbitohs at the Sydney Sports Ground. He was first grade coach from 1957 to 1961, making the semi-finals every year and the 1957 Grand Final as a 27-year-old. Following his coaching stint at Manly, Arthurson became the club's secretary, taking over from Jack Munro after Munro's passing in 1963.
