Irish business giant and multi-million-euro philanthropist Martin Naughton, founder of Glen Dimplex, has passed away at the age of 87.
A legendary titan of Irish industry and one of the most generous charitable benefactors in the country’s modern history has passed away, marking the end of a truly remarkable life that reshaped both the corporate boardroom and the classroom. On Friday, July 3, 2026, billionaire businessman, engineer, and world-renowned philanthropist Martin Naughton died peacefully at the age of 87. Tributes have poured in from political leaders, cultural icons, and major academic institutions across the entire island of Ireland, all mourning the loss of a self-made industrial visionary. Leading the national tributes, government officials praised Naughton as an absolute pillar of the economy who combined a fierce commercial ambition with an enduring, deep-seated kindness.
To understand why Naughton’s passing has caused such a profound wave of sadness, you have to look at how he actively chose to use his immense private wealth to lift others. Long before he became known as one of Ireland’s wealthiest individuals, Naughton believed that successful businesses have a moral responsibility to reinvest their profits directly back into society. Alongside his wife, Carmel, he spent decades quietly pouring millions of euros into educational equity, scientific research, cross-border peace initiatives, and the creative arts. In recognition of this lifelong dedication to others, the couple received numerous prestigious international honors, including France’s Légion d’Honneur and a rare Papal award from Pope Francis, who personally inducted them into the Order of Saint Gregory the Great for their outstanding contributions to humanity.

Geographically, Naughton’s incredible journey from a modest local engineer to a global corporate kingpin began in the border town of Newry, Northern Ireland. It was here, in 1973, that he founded a tiny startup called Glen Electric with just a handful of employees building simple oil-filled radiators. In a legendary business move that occurred just four years later, in 1977, Naughton’s small company shocked the corporate world by acquiring Dimplex, its much larger British rival, to form the multinational giant Glen Dimplex. Headquartered in County Dublin but operating major manufacturing hubs spanning the United Kingdom, the United States, and China, the family-owned empire eventually grew to employ over 8,000 workers worldwide, absorbing iconic household brands such as Morphy Richards and Lec refrigerators.
While his industrial accomplishments were massive, his true living monument resides within the walls of Ireland’s top educational and cultural centers. In 2001, the couple donated £500,000 to endow the famous Naughton Gallery at Queen’s University Belfast, followed by a spectacular £1 million personal donation in 2007 to help completely rebuild the city’s historic Lyric Theatre. Mourning his passing, Queen’s University Vice-Chancellor Professor Sir Ian Greer described Naughton as a lifelong champion of education whose immense generosity and farsighted vision have left an enduring legacy. This sentiment was echoed heavily in Dublin, where Naughton previously made history by donating €25 million to Trinity College Dublin to fund the state-of-the-art E3 Learning Foundry, a cutting-edge science and engineering center scheduled to officially open its doors to students in the autumn of 2026.
