The story goes as follows:
In the early 20th century, rumors went around that the devil had been born (in baby form) somewhere around the Levy district and dropped off at Hull House, the settlement house on South Halsted. Exactly how this came to happen varied (largely depending on the ethnicity of who was telling the story), but most variations stated that the baby had red skin, horns, and spoke English, Latin and Italian fluently. Hundreds of people came to Hull House demanding to see it. When I tell the story on tours, people tend to snicker.
But in those days, people really believed.....oh, who am I kidding? Some people STILL believe that the story was true. They give me dirty looks for saying that it wasn't, and for saying that the devil baby's ghost doesn't haunt Hull House to this day. Some of them even go to Hull House and bug the staff about it, just the way people did back in the old days. It's in the realm of possibility that some poor, deformed baby was brought there (it's a safe bet that fetal alcohol syndrome was rampant in the neighborhood, and pre-natal care barely existed), and someone saw it and let their imagination get carried away with them, but Jane Addams denied that the story had even that much truth to it, and I'm willing to take her word.
So I'll just say this once: there was never a devil baby, and there's no devil baby ghost, at Hull House. There may be some ghosts in there (I had enough weird nights on tours I brought there in 2006 to at LEAST give it a "maybe"), but the devil baby isn't one of them. Some legends that aren't true are harmless, or even beneficial to a city and its view of itself. Some of the rumors about Hull House, though, aren't harmless. There are enough TRUE stories about the place that the legends and rumors should be presented as legends, and nothing more. However, a couple of tours, in particular, have been spreading some real crap about the place. It's irresponsible on their part, since there are plenty of TRUE stories about the place that they usually ignore (if they know them at all). Devil Baby stories (a common urban legend at the time) could get ugly - in one town, a family had a mob at the door wanting to sacrifice their (perfectly normal) infant.
Most of the more famous stories about Hull House - and most of the pictures - are bogus. Smudges and glare on the window leads to a lot of 'ghost on the stairs' shots, and every "monk ghost" picture I've seen has turned out to be (I swear I'm not making this up) the reflection of someone's ear. There is no headless ghost that will follow you home if you don't cross yourself before entering the garden. The garden is not a burial ground. I'm not out to spoil anyone's fun here, but I don't think it's worthwhile to waste time hunting for ghosts that I know aren't real.
In 2006, during renovations to the building, I did run a lot of tours in which weird stuff happened there. We heard babies crying from inside the garden one night (there's no graveyard in there and no portal to the netherworld; but when Jane Addams first moved into the house, that spot was occupied by either a brothel or an undertaking parlor). For a couple of weeks the shutters were opening and closing, apparently of their own accord. And we did get a few pictures that I've yet to explain and don't really expect to.
While doing research today, I came upon a BIG article Jane Addams, the Nobel Peace Prize-winning founder of Hull house herself, wrote about the Devil Baby for Atlantic Monthly in 1916. You can read it yourself here, and I highly recommend that you do. It's a fascinating read - does anyone know which ballad she's referring to when she talks about a ballad in which a mistress demands that her lover bring her his mother's heart on a plate? I pride myself on knowing my gory folk ballads, but this one has me stumped.
Anyway, while it may be haunted, DON'T believe everything you hear, and, for goodness sake, don't go bugging the people who work in the building about ghosts, and certainly don't show up with equipment expecting to be allowed to run some hunt for the ghost of the devil baby.
