including the management of Hallmark Cards, the parent company of the hotel's owner. Several rescuers suffered considerable stress due to their experience and later relied upon each other in an informal support group. Legacy The Hyatt Regency collapse remains the deadliest non-deliberate structural failure in American history, and it was the deadliest structural collapse in the U.S. until the collapse of the World Trade Center towers 20 years later. The world responded to the Hyatt disaster by upgrading the culture and academic curriculum of engineering ethics and emergency management. In this respect, the event joins the legacies of the 1984 Bhopal disaster, the 1986 Space Shuttle Challenger disaster and the 1986 Chernobyl disaster. The disaster provides a case study teaching first responders the "all-hazards approach" to multiple disciplines across jurisdictions, and teaching university students in engineering ethics classes how the smallest personal responsibility can impact the biggest projects with the worst possible results. The American Society of Civil Engineers adopted a clear policy—which carries weight in court—that structural engineers are now ultimately responsible for reviewing shop drawings by fabricators. Trade groups such as the ASCE issued investigations, improved standards of peer review, sponsored seminars and created trade manuals for the improvement of professional standards and public confidence. The Kansas City Codes Administration became its own department, doubling its staff and dedicating a single engineer comprehensively to all aspects of each reviewed building. Kansas City politics and government were colored for years with investigations against corruption. In 1983, the disaster was cited in the argument against the Reagan administration's attempt to eliminate an agency of the National Bureau of Standards. The Kansas City Star and its associated publication the Kansas City Times won a Pulitzer Prize in 1982 for their 16 months of investigative coverage of the collapse. A memorial was dedicated by Skywalk Memorial Foundation, a nonprofit organization established for victims of the collapse, on November 12, 2015, in Hospital Hill Park across the street from the hotel. It included a $25,000 donation from Hallmark Cards. Jack D. Gillum (1928–2012), the owner of the engineering company and an engineer of record for the Hyatt project, occasionally lectured at engineering conferences for years after the tragedy. Claiming full responsibility and disturbed by his memories "365 days a year", he said he wanted "to scare the daylights out of them" in the hope of preventing future mistakes.
