of the saying as Murphy's law has been found before 1951 (see above). The next citations are not found until 1955, when the May–June issue of Aviation Mechanics Bulletin included the line "Murphy's law: If an aircraft part can be installed incorrectly, someone will install it that way", and Lloyd Mallan's book, Men, Rockets and Space Rats, referred to: "Colonel Stapp's favorite takeoff on sober scientific laws—Murphy's law, Stapp calls it—'Everything that can possibly go wrong will go wrong'." The Mercury astronauts in 1962 attributed Murphy's law to U.S. Navy training films. Fred R. Shapiro, the editor of the Yale Book of Quotations, has shown that in 1952 the adage was called "Murphy's law" in a book by Anne Roe, quoting an unnamed physicist: he described [it] as "Murphy's law or the fourth law of thermodynamics" (actually there were only three last I heard) which states: "If anything can go wrong, it will." In May 1951, Anne Roe gives a transcript of an interview (part of a Thematic Apperception Test, asking impressions on a drawing) with Theoretical Physicist number 3: "As for himself he realized that this was the inexorable working of the second law of the thermodynamics which stated Murphy's law 'If anything can go wrong it will'. I always liked 'Murphy's law'. I was told that by an architect." Anne Roe's papers are in the American Philosophical Society archives in Philadelphia; those records (as noted by Stephen Goranson on the American Dialect Society list, December 31, 2008) identify the interviewed physicist as Howard Percy "Bob" Robertson (1903–1961). Robertson's papers are at the Caltech archives; there, in a letter Robertson offers Roe an interview within the first three months of 1949 (as noted by Goranson on American Dialect Society list, May 9, 2009). The Robertson interview apparently predated the Muroc scenario said to have occurred in or after June, 1949. The name "Murphy's law" was not immediately secure. A story by Lee Correy in the February 1955 issue of Astounding Science Fiction referred to "Reilly's law", which "states that in any scientific or engineering endeavor, anything that can go wrong will go wrong". Atomic Energy Commission Chairman Lewis Strauss was quoted in the Chicago Daily Tribune on February 12, 1955, saying "I hope it will be known as Strauss' law. It could be stated about like this: If anything bad can happen, it probably will." Arthur Bloch, in the
