One hundred years ago today, on July 24, 1915, the Eastland passenger ship listed to its side in the Chicago River between LaSalle Drive and Clark Street. More than 840 people died in the disaster. That's a higher number than the fatalities in the Titanic sinking.

Last week, in advance of the anniversary, the Chicago Tribune happened to find nearly 100 black-and-white images inside two cardboard boxes in the newspaper's basement archives:

The photographs capture the aftermath of one of Chicago's worst disasters: rows of sheet-covered bodies inside a temporary morgue, two women crying while clutching a baby in a blanket, a Coast Guard crew hauling a woman out of the river, the Eastland flopped over in the water like a plastic toy in a bathtub, dozens of people atop its side, awaiting rescue.

But the most noteworthy images in a trove of glass-plate negatives recently discovered in the Tribune's basement archives are the views from inside the doomed excursion steamer, a vantage point rarely before seen, photo historians say.

There are two sets of images, one here and one here. It's worth having a look at them all and trying to imagine exactly what it was like on that day.
