Contrary to popular belief, the word "nosferatu" does not mean "vampire" or "undead" in Romanian. The term originally came from the old Slavonic word nosufur-atu, which itself was derived from the Greek "nosophoros". "Nosophoros", in ancient Greek, stands for "disease carrier".
Nosferatu borrows its look from the 1922 movie of the same name. Nosferatu was an unauthorized version of Stoker's Dracula and his widow nearly succeeded in having all copies destroyed. The movie was remade in 1979 and the Nosferatu look was further popularized by White Wolf's World of Darkness RPG setting.
