  • Connect James Henry Blake (zoologist) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of James Henry Blake (zoologist) from memory before moving on to harder problems.

Reference excerpt

James Henry Blake (July 8, 1845 – July 20, 1941) was an American zoologist and scientific illustrator who worked for the Museum of Comparative Zoology at Harvard University. He later served as an artist for the United States Fish Commission and the U.S. Geological Survey. The scientific literature contains many of his illustrations.

Life and career Blake was born in Boston on July 18, 1845. He received his schooling in Provincetown, Massachusetts, and in 1864 he enrolled in the Lawrence Scientific School at Harvard University. At Harvard, he worked as a student assistant in the conchology department of the Museum of Comparative Zoology, organizing the specimen collections under the tutelage of Louis Agassiz. In 1868, he sketched and recorded the features of mollusks collected during the 1865–66 Thayer Expedition to Brazil. In 1871, Blake accompanied the Hassler Expedition as Agassiz's assistant on this two-year deep-sea dredging trip, during which he drew specimens and supervised the fishing operations that gathered up 30,000 fish specimens. Blake's 152-page scrapbook, filled with clippings and notations chronicling the expedition, is "one of the Ernst Mayr Library’s most prized holdings."

In September 1872, having returned to Harvard, Blake resumed his work organizing and documenting the museum's mollusks. In 1875, Nathaniel Thayer’s philanthropic funding for Blake’s salary finally ran out, and he had to leave the museum. He spent five years as artist for the Vineyard Sound Survey of the U.S. Fish Commission and also worked for the U.S. Geological Survey and the Mississippi Geological Survey. Blake illustrated many zoological articles and monographs by scientists such as Samuel Garman, Harold L. Babcock, and Joel Asaph Allen. He co-founded the Boston Malacological Club, serving as the club's president from 1918 to 1919. Known primarily as a malacologist, Blake had a lifelong fascination with whales, notably illustrating Glover M. Allen's The Whalebone Whales of New England (1916). He was a member of the Boston Society of Natural History from 1870 until his death and served on its governing council. In 1894–95, he was president of the Cambridge Art Circle. Besides his scientific work, he studied art in New York, painted landscapes, and moonlighted as an art teacher. Blake married Lucinda Smith Critchett (1844–1907) in Provincetown in 1871 and had two sons with her. He died on July 20, 1941, at the age of 96 in Somerville, Massachusetts. He was buried in Mount Auburn Cemetery. Perhaps the last surviving student or employee of Louis Agassiz at the time of his death, he bequeathed most of his personal collections and artwork to the Museum of Comparative Zoology. A collection of his colored drawings of whales and mollusks made its way into the collection of the Boston Museum of Science.

Worked examples

Example 1 — a first encounter with James Henry Blake (zoologist)

Start with the simplest possible case. Write down what James Henry Blake (zoologist) 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 James Henry Blake (zoologist) 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 James Henry Blake (zoologist) 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 James Henry Blake (zoologist)

In research
James Henry Blake (zoologist) 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 James Henry Blake (zoologist) 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
James Henry Blake (zoologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1845 births, 1941 deaths, 19th-century American male artists, so understanding it makes those chapters shorter.
In everyday life
Look for James Henry Blake (zoologist) 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.
