As the U.S. Army Engineer Research and Development Center (ERDC) celebrates its 25th anniversary, “A Tradition of Innovation” traces the organization’s history from its precarious roots through its evolution into a world-class organization solving the toughest problems facing the nation and the Warfighter. This book highlights the key inflection points that shaped ERDC–from responding to national crises like 9/11 and Hurricane Katrina to changing climates, evolving military strategies and demands for greater computational power. As ERDC prepares to solve a myriad of new and escalating challenges, its engineers and scientists will build upon its tradition of innovation and lean into the cross-disciplinary culture forged during the organizations’ first quarter century.
