John Menkes

John Menkes is a biology 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 John Menkes rather than just read about it. In short: John Hans Menkes (December 20, 1928 – November 22, 2008) was an Austrian-American pediatric neurologist and author of fictional novels and plays. He identified two inherited diseases: maple syrup urine disease which is a defect in amino acid metabolism, and a defect in copper transport which bears his name.

Key takeaways

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

Reference excerpt

John Hans Menkes (December 20, 1928 – November 22, 2008) was an Austrian-American pediatric neurologist and author of fictional novels and plays. He identified two inherited diseases: maple syrup urine disease which is a defect in amino acid metabolism, and a defect in copper transport which bears his name. In addition to a career in academic medicine, he pursued a career in writing, publishing novels and plays.

Early life Menkes was born in 1928 in Vienna, Austria. His family fled Austria for Ireland days before the start of World War II, and later moved to California. He was interested in journalism, but his father, a fourth-generation physician, convinced him to go into medicine. He earned a bachelor's degree and a master's degree in organic chemistry from the University of Southern California.

Medical training After receiving his M.D. from Johns Hopkins in 1952, he was an intern at Boston Children's Hospital. There, he encountered an unusual case. A child was showing signs of decline. The mother had two previous sons and a daughter, who had undergone the same changes and she had noted that their urine had a smell reminiscent of maple syrup, unlike their two healthy sisters. The child died after one week of life. Samples of urine were examined, but no specific compound had been identified before the samples were exhausted. Among techniques, the odor was compared, by smell, to an inventory of organic chemicals. Menkes, Peter Hurst (a resident), and John Craig (pathologist) published the account in a paper that was later listed in the Science Citation Index "Citation Classics". He went to Johns Hopkins for residency in psychology. The head of child neurology, Frank Ford, was aware of his paper and suggested that he should study neurology instead. He was drafted and served as a pediatrician at the Pepperrell Air Force Base in Newfoundland for the Northeast Air Command during the Korean War. Following his military service, he trained in pediatric neurology at Bellevue Hospital in New York City In 1957, as a pediatric neurology fellow (with a research budget of $35), he encountered another case of what would be identified as maple syrup urine disease and was able to detect branched chain keto acids in the urine samples. During his fellowship, he also encountered a boy who was born healthy, but developed progressive muscle weakness (hypotonia) and seizures. The child had the characteristic finding of brittle hair. He published the accounts of five cases, and the metabolic defect was later identified as an X-linked recessive error in copper transport.

Medical practice and writing Menkes returned to Johns Hopkins in 1960, and became chief of pediatric neurology in 1964. In 1966, he went to UCLA where he established their division of child neurology. In 1974, the first edition of Textbook of Child Neurology was published and Menkes served as editor for six additional editions. That year went into private practice. He also dedicated time to writing, describing Anton Chekhov as his "idol and guiding light" for his ability to maintain his medical and writing careers. In his 1986 play, The Last Inquisitor about the last Gestapo head, Ernst Kaltenbrunner, he dealt with his own relationship to the Holocaust. The Los Angeles Times found it interesting, especially in the way he took down the fourth wall and had a character play who becomes an actor who is consumed by the role of Adolf Eichmann, but found that it was more of a cerebral than emotional experience. He revisited the theme, asking how things might have been had he been born Christian instead of Jewish in Vienna, in his 2003 novel, After the Tempest. He became a plaintiffs' expert witness in injury cases related to the pertussis vaccine and was appointed to the National Institute of Medicine's Forum for Vaccine Safety. He wrote about his experiences in the product liability debate in the form of a fictional novel, The Angry Puppet Syndrome (1999). His 2001 comedy, Lady Macbeth Gets a Divorce, received similarly mixed reviews from Variety which called it "more schematic than compelling".

Death Menkes died from complications of cancer on November 22, 2008, at Cedars-Sinai Medical Center.

Worked examples

Example 1 — a first encounter with John Menkes

Start with the simplest possible case. Write down what John Menkes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Menkes 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 Menkes 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 Menkes

In research
John Menkes appears in biology 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 Menkes 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 Menkes is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2008 deaths, Austrian emigrants to the United States, so understanding it makes those chapters shorter.
In everyday life
Look for John Menkes 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.
