Manly remains the only club to have secured at least one premiership in five consecutive decades, a record shaped by generations of contributors.
As the Sea Eagles mark their 80th anniversary, a mini-documentary, The House That Arko Built, will celebrate Ken Arthurson's influence on the club.
Arthurson turns 97 today and is widely known as 'Arko' and 'The Godfather of Manly'.
His service stretched across roles as player, captain, coach, administrator, recruiter, negotiator and leader.
After Manly lost five Grand Finals, Arthurson worked to assemble a team capable of winning the club's first premiership.
Among the players he brought to Brookvale was Bob Fulton, later named an Australian Rugby League Immortal.
As club secretary, a position comparable to a modern CEO, Arthurson oversaw a period in which Manly reached eight Grand Finals and won four premierships.
The team he built dominated the 1970s, helping establish a winning culture that remains part of the club's identity.
The documentary gathers memories from people who helped shape Manly and others who knew Arthurson well.
