>From "Bridges and their Builders," by David Steinman & Sara Watson: "The pneumatic [caisson] method was first suggested in 1647 by the physicist Papin and again in 1779 by Coulomb, but it was first applied to bridge construction by John Wright in building the piers for a bridge at Rochester, England in 1851. ... [B]y 1860 the method was generally employed throughout Europe. When Eads introduced it in America, he greatly improved it and applied it to greater depths and on a scale never before attempted. "... Eads returned to St. Louis in April of 1869 and immediately set about sinking the river piers by the pneumatic caisson method." (page 184) and on pages 236-7 concerning the Brooklyn Bridge: "... For this work, pneumatic caissons were adopted --- the new method of founding that was contemporaneously being introduced and developed on the Eads Bridge at St. Louis." I guess that one would have to say that the Eads Bridge *and* the Brooklyn Bridge were the earliest *known* uses of pneumatic caissons in the U.S. Both are great bridges built by great engineers who were pioneers in bridge building methods. That one might have been slightly ahead of the other should not be relevant. A. Roger Turk, P.E.(Structural) Tucson, Arizona
