Core Event: Passing of Professor John Donaldson

Queen Mary of Denmark has announced the death of her father, Professor John Dalgleish Donaldson, who passed away in Hobart, Tasmania, at the age of 84. The Danish Royal House confirmed the news on April 12, 2026, stating that Donaldson's health had been declining for several years. Queen Mary had visited him at the end of March during a state visit to Australia, where they shared meaningful moments together.

Background & Context: A Life in Academia

John Donaldson was born on September 5, 1941, in Port Seton, Scotland. He emigrated to Australia in 1963 with his first wife, Henrietta Clark Horne, shortly after earning his degree in mathematics and physics from the University of Edinburgh. Donaldson completed his PhD in applied mathematics at the University of Tasmania in 1967 and spent over three decades at the university, eventually becoming the Dean of the Faculty of Science before retiring in 2003. He remarried in 2001 to British crime novelist Susan Moody.

Official Statements & Responses

In a heartfelt statement, Queen Mary expressed her sorrow, saying, “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 royal family plans to hold a private memorial service in Australia to honor Donaldson's life.
