John Michael Crichton (1942–2008) was an American author and filmmaker.  His books have sold over 200 million copies worldwide, and over a dozen have been adapted into films.  His literary works heavily feature technology and are usually within the science fiction, techno-thriller, and medical fiction genres.  His novels often explore technology and failures of human interaction with it, especially resulting in catastrophes with biotechnology.  Many of his novels have medical or scientific underpinnings, reflecting his medical training and scientific background.  Crichton received an M.D. from Harvard Medical School in 1969 but did not practice medicine, choosing to focus on his writing instead.  Initially writing under a pseudonym, he eventually wrote 26 novels, including:  The Andromeda Strain (1969), The Terminal Man (1972), The Great Train Robbery (1975), Congo (1980), Sphere (1987), Jurassic Park (1990), Rising Sun (1992), Disclosure (1994), The Lost World (1995), Airframe (1996), Timeline (1999), Prey (2002), State of Fear (2004), and Next (2006).  Several novels, in various states of completion, were published after his death in 2008.  Crichton was also involved in the film and television industry.  In 1973, he wrote and directed Westworld, the first film to utilize 2D computer-generated imagery.  He also directed:  Coma (1978), The First Great Train Robbery (1978), Looker (1981), and Runaway (1984).  He was the creator of the television series ER (1994–2009), and several of his novels were adapted into films, most notably the Jurassic Park franchise.  Crichton used pseudonyms, such as Michael Douglas, John Lange, Jeffery Hudson (17^th century dwarf and a reference to Crichton’s own height of 6’9”).    https://en.wikipedia.org/wiki/Michael_Crichton  See also https://go.gale.com/ps/i.do?p=LitRC&u=googlescholar&id=GALE|H1200011627&v=2.1&it=r&sid=bookmark-LitRC&asid=efc19179   

When “hogwash” showed up in the mid-1500s, according to the Oxford English Dictionary, it meant “kitchen refuse and scraps (esp. in liquid form) used as food for pigs.”  The earliest OED example is from Jacob’s Well, an anonymous Middle English sermon cycle, written around 1450, in which the human soul is likened to a foul well in need of cleansing.  In the early 1600s, Oxford says, “hogwash” took on the sense of a “liquid for drinking that is of very poor quality, as cheap beer, wine, etc.”  In the late 1800s, the word took on the modern meaning of “nonsense; esp. worthless, ridiculous, or nonsensical ideas, discourse, or writing.”  “Claptrap” originated in the early 1700s as theatrical jargon for a “trick or device to catch applause; an expression designed to elicit applause,” the OED says.  By the early 1800s, “claptrap” was being used to mean catchy language or cheap, showy sentiment, as in this OED citation, which we’ve also expanded, from Byron’s satirical poem Don Juan (Canto II, 1819):  “I hate all mystery, and that air / Of clap-trap, which your recent poets prize.”  And by the late 1800s, the word had acquired its modern meaning of nonsense.  https://www.grammarphobia.com/blog/2018/06/hogwash-claptrap.html
