I hope it's okay to post a NYC-centric question here (I know there are lots of New Yorkers on MeFi). Embedded in the sidewalk pavement along Broadway, from around Battery Park up to about the Woolworth Building (and perhaps farther), are these stone slabs that contain an event or a famous person, followed by the date of the event or some date related to the person. There's one every few yards. Does anyone know what these are for, who put them there, or anything else about them?
