— Mattathias after his announcements.
Mattathias Medicalschool is Count Olaf's seventh disguise and appears in The Hostile Hospital. He claims to be the new Human Resources director of Heimlich Hospital, after Babs. He also claims to be the head of Hospital Administration, but has nothing to do with party planning.
In the book, he is only a voice on an intercom, and his surname is not mentioned.
In the TV show, he appears visually as a doctor. He also speaks in a voice similar to early 1900's radio presentors.
