Norman W. Walker

Norman W. Walker is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Norman W. Walker rather than just read about it. In short: Norman Wardhaugh Walker (4 January 1886, Genoa, Italy – 6 June 1985, Cottonwood, Arizona) was a British businessman and pioneer in the field of vegetable juicing and nutritional health. He advocated the drinking of fresh raw vegetable and fruit juices for health.

Key takeaways

  • Norman W. Walker belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Norman W. Walker to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Norman W. Walker from memory before moving on to harder problems.

Reference excerpt

Norman Wardhaugh Walker (4 January 1886, Genoa, Italy – 6 June 1985, Cottonwood, Arizona) was a British businessman and pioneer in the field of vegetable juicing and nutritional health. He advocated the drinking of fresh raw vegetable and fruit juices for health. Based on his design, the Norwalk Hydraulic Press Juicer was developed. This juicer was produced until its manufacturer, Norwalk, Inc., located in Bentonville, Arkansas, ceased operations in October 2021. Walker was the author of at least 11 books on nutrition and healthy living, published from 1936 to 1981. As of 2006, many book reviews and promotional websites wrongly claim that Walker reached the age of, variously, 109, 113, 116, 118, or 119 years. Several official sources, including the US Social Security Death Index and a grave marker all indicate that he lived to be 99 years of age.

Biography

Walker was born in Genoa, Liguria, Italy on 4 January 1886 to Robert Walker, a Baptist minister from Scotland, and Lydia Maw Walker. He was the second of the six children of Rev. and Mrs. Walker that lived to adulthood. As a young man, he discovered the value of vegetable juices while recovering from a breakdown in a peasant house in the French countryside. Watching a woman in the kitchen peel carrots, he noticed the moistness on the underside of the peel. He decided to grind them, and had his first cup of carrot juice. Walker followed his parents and siblings to the United States, leaving England in 1910 on the S.S. Lusitania, and arriving in New York City in October of that year, where Walker worked at various occupations (although he gave his occupation as "painter" in his immigration interview). Although Walker has never shown up in any publicly released Federal Censuses, he and wife Margaret were enumerated in both the interim New York State Censuses of 1915 and 1925, where his birthplace was stated as "Italy" and occupations given for him as "janitor" and "real estate", respectively. Norman W. Walker married Margaret Bruce Olcott, a New Yorker, on 11 June 1913 in New York City [New York State Marriage Index (on-line), Marriage Certificate No.13485]. Margaret Walker died in New York City in November 1970 (NY Times obituary and Social Security Death Index). It is not known when and where Norman and Margaret divorced, but the 18 January 1943 issue of the Reno (NV) Evening Gazette reported a Marriage Application for Norman W. Walker of San Francisco and Helen Ruth Kerby of Carson City. There is no indication Walker had children from either marriage. On 22 November 1918, Walker was granted US citizenship by the New York State Court. On 6 May 1933, The New York Times reported that "An indeterminate penitentiary term of not more than three years was imposed by Judge Allen in General Sessions yesterday on Norman Walker, 47 years old...." This was the fifth NY Times article in this matter, commencing in 1932. The original charges involved advertisements placed in the New York Times by Walker, as managing director for The Broughton Institute of Ortho-Dietetics in NY City, wherein he allegedly promised employment with this school following completion of a six-weeks course. Neither employment nor requested return of the $150 tuition followed. According to a Probation Officer testifying at the Walker trial, 30 graduated students lost a total of $4,500 (approximately $80,000 in 2015 dollars per CPI calculation). It is currently unknown how much incarceration time, if any, Walker actually served. Later, Walker moved to Long Beach, California. With a medical doctor, he opened a juice bar and offered home delivery service. By 1930, they had devised dozens of fresh juice formulas for specific conditions. Walker believed colon cleansing with fresh juices was the key to good health. Believing hand juicers to be insufficient, Walker designed his own mechanical juicer, the Norwalk, in two parts – a grinder to slowly grind the vegetables and a press to extract the juice. When the San Francisco health department banned unpasteurised vegetable juices such as Walker's, he began manufacturing his juice machine in Anaheim, California. He kept the plant going in spite of the steel shortage during World War II. In the late 1940s, he moved to St. George, Utah, where he found an old cotton mill, ideal for his juice plant, but he was again suppressed by local health department regulations. He sold his share of the factory to his business partner and started publication of his own health magazine, The New Health Movement Review. For several years, Walker ran a health ranch in Arizona. Eventually, he gave up the ranch and devoted himself entirely to writing. Walker observed a raw food diet, with fresh raw juices, until his death. Although claims have been made that he was both physically and mentally healthy and active up to the day of his death when he peacefully died during his sleep one night at his home in Cottonwood, Yavapai County, Arizona, no "official" evidence of such claims, such as an Arizona death certificate, have, so far, ever publicly surfaced.

Worked examples

Example 1 — a first encounter with Norman W. Walker

Start with the simplest possible case. Write down what Norman W. Walker claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Norman W. Walker 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 Norman W. Walker 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 Norman W. Walker

In research
Norman W. Walker appears in science 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 Norman W. Walker 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
Norman W. Walker is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1886 births, 1985 deaths, 20th-century American inventors, so understanding it makes those chapters shorter.
In everyday life
Look for Norman W. Walker 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.
