The 51-year-old had more than 25 years experience in the industry working on major music, entertainment, sporting and other live events.
The Dubliner began his career as a public servant but always had an interest in the world of entertainment and worked at various music events in his spare time.
In 1986 he went into the business of ticket selling full-time as general manager of the new Ticket Shop in HMV Stores based on Grafton Street and Henry Street in Dublin.
Along with his business partner, Tommy Higgins, O’Connor started Ireland’s first computerised ticketing operation in 1992, and five years later they entered a joint venture arrangement with Ticketmaster. He was later made managing director of Ticketmaster Ireland in 2004.
Mark Yovich, president of Ticketmaster International, said: "Eamonn has been an irreplaceable part of the Ticketmaster family for more than 30 years and was an inspiring, entertaining, talented and truly unique personality.
"Anyone who knew Eamonn, as a colleague or a friend, will have been unforgettably touched by the Eamonn O’Connor magic. He was one of a kind and we will miss him terribly.
"Our thoughts are with his family and our colleagues in Ireland during this time."
