/ˈmərfiz ˈlɑ/

Origin: Apparently from a proper name, combined with an English element. Etymons: proper name Murphy , law n.¹

Etymology: Apparently < the name of Captain Edward A. Murphy, who performed studies on deceleration for the U.S. Air Force in 1949 (during which he noted that if things could be done wrongly, they would be) + law n.¹ (see R. A. J. Matthews The Science of Murphy's Law in Proc. Royal Inst. (1999) 70 75); see quot. 1962 for another theory (numerous other suggestions have also been made).The notion that ‘If anything can go wrong, it will’ is often referred to earlier, sometimes being referred to as the fourth law of thermodynamics (1944 or earlier; compare quot. 1953; see also quot. 1951).

colloquial.

A supposed law of nature, humorously adapted to different contexts, expressing the certainty that in any particular situation anything that can go wrong, will go wrong. Cf. Sod's Law n. at sod n.³ Phrases 2.The ‘law’ is usually quoted as ‘If anything can go wrong, it will’.

1953 A. Roe Making of Scientist 46 There is, for example, the physicist who introduced me to one of my favorite ‘laws’, which he described as ‘Murphy's law or the fourth law of thermodynamics’ (actually there were only three the last I heard) which states: ‘If anything can go wrong it will.’

Murphy was a careless, all-thumbs mechanic who was prone to make such mistakes as installing a propeller backwards.

1970 Sci. Amer. June 143 Recently..I learned of a governing principle known as Murphy's first law of biology. It states: ‘Under any given set of environmental conditions an experimental animal behaves as it damn well pleases.’
