This biography charts the life of the Dingle-born Chief Executive of the ESB, who revolutionized corporate life during the 1980s and 90s. He became one of Ireland's leading business people of the twentieth century, when he transformed the ESB into a world-class electricity provider and a highly efficient organization, updating the network services to meet demand. He was also a key player in the revitalization of the Irish economy, giving teeth to the Celtic tiger. His vision was to make the ESB 'the best electricity facility in the whole world', advising and selling into the economies of North and Central America, Africa and the Far East. He joined the ESB as a clerk in June 1945, aged nineteen, became Section Head of Personnel in February 1955 (employing Brendan Kennelly), and quickly worked his way to the top. Following the success of the Shannon Scheme, and the exploitation of the gas fields on Ireland's shorelines during the late 1970s, with his friend Charles Haughey he initiated the important cross-border project linking the Erne and the Shannon in 1992 and restored the Ballinamore-Ballyconnell canal to give life to the dying communities on both sides of the border.
He conducted comprehensive industrial relations' agreements with the trade unions and played a key role in ensuring national harmony in the workplace during the 80s, a decade of fast-moving change with massive technological advancements and concomitant reducancies. He was also a significant patron of the arts, ensuring and developing the sponsorship of painters, sculptors and musicians, while dispensing largesses on Ireland's racetracks (one of the Curragh race-trophies is named in his honour). His younger brother is well-known GAA broadcaster, Micheal O Muircheartaigh whose autobiography was recently published.
