In a deeply moving announcement that has touched hearts around the world, Queen Mary of Denmark has shared the sorrowful news of her beloved father’s passing. Professor John Dalgleish Donaldson, the Scottish-born Australian academic and father of the Australian-born Queen, died on 11 April 2026 in Hobart, Tasmania, at the age of 84. His health had been gradually declining for some time, but the timing of his death — just weeks after Queen Mary’s emotional visit during the Danish royal couple’s state tour of Australia — has left many describing the moment as profoundly poignant.

Queen Mary’s father dies after suffering years of health problems aged 84 – The Mirror

Queen Mary, 54, released a personal and heartfelt statement through the Danish Royal House: “My heart is heavy, and my thoughts are grey. My beloved father has passed away. But I know that when the grief settles, the memories will brighten my day, and what will remain strongest is love and gratitude for everything he gave me and taught me.”

The palace confirmed that Queen Mary and King Frederik X had visited Hobart at the end of their March 2026 state visit to Australia, where the Queen spent precious private time with her father. They shared “several good and close moments together,” according to the official statement. Many observers and royal watchers have been moved by the idea that Professor Donaldson appeared to hold on long enough to see his daughter one final time in her hometown — a quiet, tender farewell that feels almost poetic in its sadness.

Queen Mary of Denmark’s father, John Dalgleish Donaldson, dies aged 84 in Tasmania | 7NEWS

Born on 5 September 1941 in Scotland, John Dalgleish Donaldson emigrated to Australia with his first wife, Henrietta (Etta) Clark Horne, in 1963. He built a distinguished academic career as a Professor of Applied Mathematics at the University of Tasmania, where he earned his PhD. Known for his intellect, quiet strength, and dedication to family, he and Etta raised four children in Hobart, with Mary — the youngest — born in 1972 at the Queen Alexandra Hospital in Battery Point.

Tragedy struck the family earlier when Etta passed away in 1997 following surgery. John later remarried Susan Moody. Throughout his life, he remained a grounded, unassuming figure even after his daughter’s fairy-tale romance with then-Crown Prince Frederik captured global attention at the 2000 Sydney Olympics. He walked Mary down the aisle at her 2004 wedding in Copenhagen and was later honoured with the Order of the Dannebrog for his connection to the Danish royal family.

Queen Mary’s very special royal wedding moment with her dad

Queen Mary’s journey from a Tasmanian university student to Queen of Denmark has always carried deep ties to her Australian roots and her father’s influence. In recent years, as his health faded, those family connections became even more cherished. Her March visit to Hobart — which included an emotional, unscheduled speech where she spoke of Hobart as a place close to her heart — now carries added significance. Photos from that period, including one reportedly taken by the Queen herself of her father, have been shared alongside the announcement, amplifying the sense of a final, loving goodbye.

The news has prompted an outpouring of sympathy from across Australia, Denmark, and the international royal community. Tributes highlight Professor Donaldson’s legacy not only as an accomplished mathematician but as a devoted father who instilled values of education, resilience, and humility in his children. A private memorial service for the family is planned for a later date.

For Queen Mary, who balances royal duties with her strong connection to Australia, this loss represents a deeply personal chapter. In her statement, she emphasised gratitude over grief in the long term — a reflection of the quiet strength she often displays in public life. King Frederik and the couple’s four children — Crown Prince Christian, Princess Isabella, Prince Vincent, and Princess Josephine — are supporting her through this time of mourning.

The story of John Donaldson’s final weeks has resonated strongly with many, evoking the universal experience of saying goodbye to a parent. The gentle timing — that he seemed to wait until he could see his daughter, now a queen, one last time in the place where she grew up — has left countless people reflecting on love, family, and the quiet endurance of parental bonds.
