HOBART (Azat TV) – John Donaldson, the father of Denmark’s Queen Mary, has passed away in his hometown of Hobart, Tasmania, at the age of 84. The Danish Royal House confirmed the news on Sunday, noting that the professor of applied mathematics had been in declining health for several years.
Academic Legacy and Personal Bonds
Born in Scotland in 1941, Professor John Dalgleish Donaldson moved to Australia in 1963, where he established a distinguished career in academia. Beyond his professional contributions to mathematics, Donaldson remained a central figure in the life of his daughter, Mary, who ascended to the Danish throne in January 2024. He famously supported her during her 2004 wedding to then-Crown Prince Frederik, providing a grounding presence as she navigated her transition into royal life.
A Final Visit Amid Declining Health
The Queen’s grief follows a poignant final meeting between the two. During a state visit to Australia in March—her first to the nation since King Frederik X’s accession—the Queen spent time with her father in Hobart. The Royal House reported that the two shared several meaningful moments during that trip, which now serve as a final connection between the monarch and her family roots in Tasmania.
Private Arrangements and Public Mourning
In a personal statement, Queen Mary expressed her profound loss, stating, “My heart is heavy and my thoughts are grey. My beloved father has died.” She noted that while the current grief is immense, she finds solace in the memories of the love and guidance he provided throughout her life. The family has announced that a private memorial service will be held in Australia at a later date, and the Danish Royal House has opened an online book of condolences for the public to share their sympathies.
The passing of John Donaldson serves as a reminder of the personal lives behind the institution of the monarchy, highlighting the enduring influence of his academic background and Australian heritage on the Queen’s public and private identity.
