Edward Aloysius Murphy, Jr. (January 11, 1918 – July 17, 1990[1]) was an American aerospace engineer who worked on safety-critical systems. He is best-known for the eponymous Murphy's Law, which is said to state, "Anything that can go wrong will go wrong."

Following the end of hostilities, in 1947 Murphy attended the United States Air Force Institute of Technology, becoming R&D Officer at the Wright Air Development Center of Wright-Patterson Air Force Base. It was while here that he became involved in the high-speed rocket sled experiments (USAF project MX981, 1949) which led to the coining of Murphy's Law.[3]
