Jacobini is an Italian opera singer who appeared in The Calculus Affair.
Trivia[]
- Hergé makes another reference to his friend in The Calculus Affair without actually specifying that it is the same character as before. However, both characters (the one in Cigars of the Pharaoh and the one in The Calculus Affair) have the same last name. His initials are therefore unknown. However, he is referred to as E.P. Jacobini both in the magazine version and the animation version.
- Just like E.P Jacobini, Hergé seemed to have "italified" his friend's last name, but the letter J doesn't exist in Italian.
