Reference excerpt

John Fitzallen Moore (February 23, 1928 – January 31, 2018) was an American physicist, the son of authors Virginia Moore and Louis Untermeyer. His last name was legally changed after his parents' divorce. His work in military electronics, communications, and spectroscopy culminated in medical electronics and x-ray products with the founding of the company Bio-Imaging Research.

Early life After attending schools in Scottsville, Virginia and High Mowing School in Wilton, New Hampshire, Moore received a B.S. in nuclear physics from MIT in three years (where he and Walter Marvin Jr. founded the Tech Model Railroad Club in 1946), and won a National Science Foundation fellowship that led to an M.S. in solid-state physics from Harvard's School of Applied Science.

Professional career His first full-time employment was at Raytheon in Waltham, Massachusetts, where he worked on radar and telemetry. At Hycon Eastern (Cambridge, Massachusetts; later acquired by Northrop), he moved from classified missile technology to become Systems Manager of a communications design office in Bangkok, Thailand. On his return, he again worked in aircraft and missile telemetry as Director of Research and Engineering at ASCOP (Princeton, New Jersey; later a division of EMR/Schlumberger). In 1960, he joined Lockheed Electronics in Plainfield, New Jersey, where he advanced from Manager of Operations Analysis to Scientific Advisor to the President, while contributing to "moon-bounce" communication systems and optical signal processors, and creating an infrared laboratory and corporate acquisition analysis. While there, he was appointed to the Lockheed Corporate Research Council, and also attended Columbia University in New York half-time. For the latter, his Ph.D. thesis proved experimentally that carbon dioxide in the atmosphere of Venus has enough greenhouse effect to warm its surface to the spacecraft-observed temperature of over 460 °C (860 °F). After receiving his doctorate, Moore created new designs in spectroscopy and fluorometry as Director of Product Development at Spex Industries in Metuchen, New Jersey. In 1976 he joined EMI Medical, the inventor of X-ray CT scanning, in Northbrook, Illinois. There, he advanced to Vice-President of Engineering, and built the team that created the first CT scanner to take a picture in under 3 seconds. When EMI got out of the medical electronics business, he founded Bio-Imaging Research (Lincolnshire, Illinois). Initially, BIR created the world's first one-second CT scanner for Toshiba, and then branched into MRI, ultrasound, and industrial x-ray scanners, including the megavolt x-ray systems that inspect trucks and cargo containers at ports and border crossings. He was awarded the Chicago Area High-Tech Entrepreneur of the Year in 1987 and 1989. In 2006, he sold BIR's medical division to Toshiba Medical, and in 2007 sold its industrial and security divisions to Varian Medical Systems. Moore served on several standards committees for medical imaging, and was Chairman of the Surface Weapons Board of the U.S. Naval Research Advisory Committee. He has published and presented numerous papers, including before the World Health Organization in Geneva. He retired after 27 years on the board of TC Manufacturing, and consulted in medical and radiation physics until dying in 2018.

Personal life He had five children (Robin [deceased], Sheila, Marjorie, Deborah [deceased], and Laurel) by his first marriage in 1948 to Joan Elizabeth Sanders (1928–1998), and two children (Jonathan M. Moore and Cris Moore) by his second marriage in 1963 to Betty-Ann Jorgensen (1938-2020). He collected original-cast musical comedy recordings and license plates, and his other interests included N-scale model railroading, mathematical games, and science fiction.

Worked examples

Example 1 — a first encounter with John Fitzallen Moore

Start with the simplest possible case. Write down what John Fitzallen Moore claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John Fitzallen Moore before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John Fitzallen Moore ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John Fitzallen Moore

In research: John Fitzallen Moore appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses John Fitzallen Moore in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: John Fitzallen Moore is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2018 deaths, American people of German-Jewish descent, so understanding it makes those chapters shorter.
In everyday life: Look for John Fitzallen Moore outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
