"Rat Man" was the nickname given by Sigmund Freud to a patient whose "case history" was published as Bemerkungen über einen Fall von Zwangsneurose ['Notes Upon A Case of Obsessional Neurosis'] (1909). The nickname derives from the fact that the patient developed a series of obsessive fantasies in which, in Freud's words, "rats had acquired a series of symbolic meanings, to which...fresh ones were continually being added".
To protect the anonymity of patients, psychoanalytic case-studies would usually withhold or disguise the names of the individuals concerned ("Anna O"; "Little Hans"; "Wolf Man", etc.). Recent researchers have decided that the "Rat Man" was in fact a clever lawyer named Ernst Lanzer (1878–1914)—though many other sources maintain that the man's name was Paul Lorenz.
The case study was published in 1909 in Germany. Freud saw the Rat Man patient for some six months, despite later claiming the treatment lasted about a year. He considered the treatment a success.
Rat-Man is an Italian comic about an inept superhero of the same name, created by Leonardo Ortolani in 1989. Although it was initially meant to be a satire of other superheroes, most prominently Batman, it has since evolved into an independent comic sporting a complex, evolving continuity. The comic is well known for its nonsense humor à-la Monty Python, its engaging storytelling and its frequent breaking of the fourth wall. Ortolani often pays both direct and indirect tribute to other comic authors (Jack Kirby above everyone else) and he frequently makes his characters use pop-culture references, either generic or specific to the native Italian context and background. The comic is currently being published by Panini Comics both as new installments under the name of Rat-Man Collection and as reprints of older stories in Tutto Rat-Man.
The character of Rat-Man appeared for the first time in the second issue of Spot, a supplement to the Italian magazine L'Eternauta #86 of June 1990, shortly after Leonardo Ortolani won a young artists' contest. From 1990 to 1995 Rat-Man was published on the fanzine Made in USA. After the debut, Leo Ortolani chose to self-publish the comic alongside his primary job as a geologist; however, in 1997 Leo signed a contract with Marvel Italia, today a brand owned by Panini Comics (and, at the time, a branch of Marvel Comics itself), to publish the comic under the Marvel brand, which allowed Leonardo to become a full-time comics author. The contract also allowed him to use popular Marvel characters like Captain America, Wolverine, Doctor Doom and Elektra in Rat-Man stories; however, copyright problems have since prohibited such use of characters in the Rat-Man world.
The day he got bit by a rat
He wanted to kill all the cats
His hair it turned grey on that day
He then grew a tail and some fangs
He's not batman
He's the ratman
Rabies foaming
From his mouth, yeah!
And now he looks just like a rat
He's killing and eating the cats
He's out on the streets every night
You'd better stay out of his sight
He's not batman
He's the ratman
Rabies foaming
From his mouth, yeah!
