The Grand Duke died on 23 April 2019, more than a week after he was first admitted to hospital for a pulmonary infection.

"Adieu"
Luxembourgish pianist David Ianni, known for his project "My Urban Piano", mourned the death of the monarch and decided to compose a piece in honour of the Grand Duke: "When I heard the news, it became clear to me what an exceptional human being he was, kind and warm-hearted. I sat down at my piano and played for two or three days without a break, until my piece in his honour, entitled Adieu, was finished."
Although a video clip had been planned for the music on 23 April, the health crisis put a halt to that project. Ianni discussed his plans with Grand Duke Henri it was agreed that the video would be published on the 100th birthday of Grand Duke Jean.
