On September 29, 2023, the Helsingborg Symphony Orchestra, in collaboration with the City of Helsingborg and the Dunkerintressena, held a jubilant tribute concert in memory of Henry and Gerda Dunker's significant contribution to the City of Helsingborg and its residents. During the concert, a short film about the Dunker couple's accomplishments was presented.
Tribute speeches were delivered by the Chairman of the Municipal Council, Mats Sander, and the CEO of Dunkerintressena, Göran Pelvén. In connection with this, a symbolic check of 104 million SEK was handed over to the city, equivalent to the 2023 distribution from the foundations.
