Ruth Crosby Noble

Ruth Crosby Noble 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 Ruth Crosby Noble rather than just read about it. In short: Ruth Crosby Noble (1896/1897 – March 1988) was an American author and herpetologist. Working for the American Museum of Natural History, she and her husband Gladwyn Kingsley Noble discovered a new species of frog, the Eleutherodactylus ruthae, named for her.

Key takeaways

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

Reference excerpt

Ruth Crosby Noble (1896/1897 – March 1988) was an American author and herpetologist. Working for the American Museum of Natural History, she and her husband Gladwyn Kingsley Noble discovered a new species of frog, the Eleutherodactylus ruthae, named for her. Noble later authored The Nature of the Beast, a book on animal behavior.

Life and career Born Ruth Elizabeth Crosby in 1896 or 1897, she was brought up in Hartford, Connecticut, and studied at Wellesley College in Massachusetts. While a student there, she met her future husband, Gladwyn Kingsley Noble, then a student at Harvard University. They would have two sons. She later moved to New York, and worked as an assistant at the departments of education and herpetology of the American Museum of Natural History from 1919 until 1923. At the museum, she worked to make museum exhibits more accessible to blind people. She was also a member of the American Association of University Women, and was active within the United Nations. While at the museum, the Nobles undertook an expedition to Hispaniola to study the rhinoceros iguana and the Hispaniolan giant tree frog, both of which were very poorly known to science at the time. The Nobles were able to capture and send to the museum more than 200 live frogs and 40 iguanas: Gladwyn Noble would write that they had been "fortunate in finding both forms and in working out their life histories". She and her husband discovered the frog Eleutherodactylus ruthae during an expedition in the Dominican Republic financed by the museum; the frog was named after Ruth by her husband. While working at the museum, she pursued a master's degree at Columbia University. In 1945, Noble published The Nature of the Beast, a book written on animal behavior based on research and notes by her husband. It is a compendium work written in easy-to-understand English, and incorporated material from both natural history observations and laboratory experiments. Recurring themes in its 17 chapters include social relations and sensation in animals. The manuscript was read by both psychologists and naturalists prior to publication: Robert Yerkes, Frank Beach, and Ernst Mayr were among those given access to portions of it. A review of the book in the Psychological Bulletin commended the breadth with which its material was covered without sacrificing detail, and recommended its use in courses on comparative psychology. Writing in the Annals of the Entomological Society of America, a reviewer stated that the book had the "rare quality of combining entertainment with sound scientific value".

Personal life Noble was a member of the First Presbyterian Church of Englewood and president of the Englewood Women's Club.

Death Noble died on March 15 or March 27, 1988, aged 91, at a nursing home in Allendale, New Jersey. She was survived by her two sons and two grandchildren.

Worked examples

Example 1 — a first encounter with Ruth Crosby Noble

Start with the simplest possible case. Write down what Ruth Crosby Noble 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 Ruth Crosby Noble 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 Ruth Crosby Noble 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 Ruth Crosby Noble

In research
Ruth Crosby Noble 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 Ruth Crosby Noble 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
Ruth Crosby Noble is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890s births, 1988 deaths, 20th-century American women biologists, so understanding it makes those chapters shorter.
In everyday life
Look for Ruth Crosby Noble 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.
