Queen Mary of Denmark has shared a heartfelt message following her father’s death just weeks after she and her husband King Frederik X visited Australia.

Professor John Dalgleish Donaldson, the father of Queen Mary, died on April 11 at 84 in Tasmania.

Queen Mary thanked well-wishers on Instagram who have been extending their sympathies since the Danish royal house announced his passing on Sunday.

‘My heartfelt thanks to the overwhelming number of messages, flowers and warm thoughts regarding my father’s death,’ she wrote.

‘The enormous amount of empathy has touched us deeply and means more than words can say’.

The message was also shared in Danish and many followers responded to the post by sending their thoughts to the grieving Australian-born Queen.

‘Sending all our love from Down Under at this sad time,’ one person wrote.

‘Lots of loving thoughts for this hard time for Queen Mary. So even harder when you now live so far away. Us Danes know that too well,’ another said.

In announcing Professor Donaldson’s passing, his daughter wrote that he would remain with her in spirit, even in death.

‘My heart is heavy, and my thoughts are grey. My beloved father has passed away,’ Mary said in a statement last week.

‘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.’

Denmark’s royal house said Prof Donaldson’s health had been declining over the past few years and Mary visited him in late March.

The family will hold a private memorial service at a later date.

Prof Donaldson was a Professor of Applied Mathematics, born in Scotland on September 5, 1941.

He moved to Tasmania with his first wife, Henrietta Clark Horne, in November 1963.

The couple welcomed their daughter, Mary Elizabeth Donaldson, on February 5, 1972, in Hobart.

The now Queen of Denmark arrived in Australia alongside King Frederik X for a six-day state visit running from March 14 to March 19 – the couple’s first official trip to the country since ascending the throne in January 2024.

At the end of that trip, Mary set aside time to visit her father.

The retired mathematics professor had previously missed several significant family milestones due to his frailty – including Princess Isabella’s confirmation and Mary’s own coronation in Denmark.

Royal officials previously confirmed Mr Donaldson was unable to travel long distances because of his health.

Mary herself acknowledged the emotional reality at the time, saying: ‘He is getting to be an elderly gentleman and he is not well enough to take the long trip back to Denmark for a confirmation, but he is with us in our hearts.’
