Regarding the Great Chicago Fire of 1871: I understand that the whole Mrs. O’Leary’s cow thing is probably a myth. However, from what I’ve read, historians are certain that the fire did start at a specific place, near or at the place where the O’Leary home stood.
Is there anything in modern Chicago marking that site? An historical marker of some kind? What kind of neighborhood is it in? (I believe the address of the O’Leary barn was 141 DeKoven St., IIRC). Also, what happened to Mrs. O’Leary and her family? Did they die in the fire? Run out of town by angry mobs?
Which part of modern Chicago stands on the site of the Columbian Exposition? I understand the site was destroyed by fire (not THE fire, but a different one). Are there any extant buildings or artifacts from the Exposition?
Finally: what part of modern St. Louis stands where the 1904 World’s Fair took place? Any extant remnants of the Fair?
I think I can answer the St Louis part of the question. The Worlds Fair took place in Forest Park, and I believe the large wrought-iron bird cage at the zoo is the only remnant from the World’s Fair still in existence.
I believe the large pavilion at the top of Art Hill in Forest Park was also built for the Fair.
One of St. Louis’ favorite myths is that the giant Ferris wheel from the Fair, instead of being dismantled and sold for scrap, was actually buried somewhere nearby. Of course, no one in the last 100 years has been able to figure out where, but we’re sure it’s just waiting to be unearthed.
The site of the Columbian Exposition was held in Jackson Park, which in South Chicago. The midway extended between 59th and 60th streets, and is now marked by Midway Plaisance Park. See here for more information.
Out of over 200 buildings on the grounds, only one remains today. What was the Palace of Fine Arts is now the Museum of Science and Industry. The Statue of the Republic standing at the foot of 65th street is a replica of one which stood at the fair.
Here is a map of the area. The large green area on the right is Jackson Park, the building at the top of the green area is the Museum of Science and Industry, and the green strip extending west is Midway Plaisance Park.
The Chicago Fire Academy now stands on DeKoven St. There’s a sculpture in front of the building commemorating the fire. The spot where the fire started is inside the building and is marked on the floor.
As St. Louisans know, the sledding Mecca “Suicide Hill” (also known as Art Hill) was originally a cascading waterfall in front of the Pavillion.
And here’s some trivia: the main walkway at the 1904 World’s Fair was called “the Pike” - this is the origin of the phrase “coming down the Pike”
(My neighborhood was the site of the Polynesian Village, where they supposedly ate dog. In my family that story is almost immediately followed by the “ferris wheel” story)
Garfield226 has got the essential answer. One could also make a case that the original heart of the Art Institute counts as an extant building, since it was initially used as part of the fair, though obviously this was pretty far removed from the main site. I also believe, without checking, that it’s have been built anyway and so the significance of it as an Exposition building is a bit beside the point.
They all easily survived. For a start, their house survived - there’s a photo of the intact cottage after the fire in Chicago: Growth of a Metropolis (Chicago, 1969) by Mayer and Wade. Regardless of exactly where it started, the fire had burnt northwards away from their property. An inquest was held that autumn into the cause and both Mrs. O’Leary and various family members testified as to what they remembered. About their subsequent fates, I’ve no idea.
A little more poking around threw up this passage from City of the Century (1996; Touchstone, 1997, p165) by Donald Miller on the fate of Catherine O’Leary:
His main source is an article about her in Chicago magazine from October 1978. This could be consistent with samclem’s 1893 citation, though there’s the issue of where “there” is in it and whether a widow’s war pension counts as charity.
