Bruno de Finetti was born in Innsbruck in 1906. The house of his birth in Adolf-Pichler-Straße (now Conradstraße 8) still exists.
The famous "De Finetti Theorem" was published in 1931: Funzione caratteristica di un fenomeno aleatorio (Atti della R. Academia Nazionale dei Lincei, Serie 6. Memorie, Classe di Scienze Fisiche, Mathematice e Naturale, 4:251-299, 1931). Thus there is the opportunity to commemorate the 80th anniversary of his theorem. An early essay on subjective probability appeared in 1931 as well: Sul significato soggettivo della probabilita (Fundam. Math. 17, 298-329, 1931).
