Horace King, a former slave, formed the King Brothers Bridge Company in the 19th century. There was no relation to the other King Bridge Company, although strangely enough, the King Iron Bridge Company built an iron bridge in this same location in 1882. I just wanted to post an excerpt from his Wikipedia article that I found pretty amazing:
"In 1849, the Alabama State Capitol burned, and King was hired to construct the framework of the new capitol building, as well as design and build the double spiral entry staircases. King used his knowledge of bridge-building to cantilever the stairs' support beams so that the staircases appeared to "float", without any central support."
That's pretty amazing for a man who was still a slave just 3 years earlier.
I attached one of my photos of it. Here is a link to a HABS photo that shows a different angle (http://en.wikipedia.org/wiki/File:Alabama-State-Capitol-spiral-staircase.jpg)
I strongly suggest you read his Wikipedia entry. http://en.wikipedia.org/wiki/Horace_King_%28architect%29
