Working Under Pressure: Scientific Considerations in the Construction of the Eads Bridge
Friday, December 10, 2010 @ 10:00 AM-11:30 AM
Featured Speaker: Hal Harris, Ph.D., 2010 Science Educator Award Recipient, Academy of Science – St. Louis; Professor, Department of Chemistry, University of Missouri – St. Louis
One of the architects behind the founding of The Academy of Science – St. Louis, James B. Eads, is also the architect and engineer behind the building of one of St. Louis’ most iconic landmarks– the Eads Bridge. Familiar to all St. Louisans, the bridge is a marvel worthy of awe, even 135 years after it was opened. Besides working under the constraints of engineering goals designed to be impossible to meet, Mr. Eads, had to deal with the challenges of excavating under the Mississippi to bedrock 100 feet below the river surface. His workers labored by torchlight in caissons Eads had designed, at pressures above 60 psi (pounds per square inch). Fourteen men died and more than one hundred were affected by “the bends,” whose scientific investigation began with Eads’ first (and last) bridge. Don’t miss this captivating tale of the science in the building of the world’s first alloy steel bridge.
