Dionys Pruckner (1834–1896) was a noted pianist and music teacher at Stuttgart. He was a student of Franz Liszt from 1852 until about 1855 who did concert tours throughout Europe. In 1859 he was appointed to the faculty of the Stuttgart Conservatory. Pruckner was a member of the masonic lodgeWilhelm zur aufgehenden Sonne in Stuttgart.
He is buried in Section 5 (Abteilung 5) of the Pragfriedhof (de) cemetery in Stuttgart, together with his wife Silly Pruckner (1837-1901). On his gravestone is a bronze relief of his head made by the sculptor Karl Donndorf (de) in 1893.
