Reference excerpt

Katharine Julia Scott Bishop (June 23, 1889 – September 20, 1975) was a trained anatomist, medical physician, researcher and educator best known for co-discovering Vitamin E.

Early life In 1889, Bishop was born in New York as Katharine Scott, to Walter and Katherine Emma (Campbell) Scott. She attended the Somerville High School (Massachusetts) for high school and later received her undergraduate degree from Wellesley College in 1910. After taking premedical courses at Radcliffe College, Bishop went on to graduate from The Johns Hopkins University School of Medicine and earned her medical degree in 1915.

Discovery of Vitamin E After graduating from medical school, Bishop moved to Berkeley to teach histology in the anatomy department at the University of California Medical School until 1923. During this time, Bishop did her medical research with anatomist and endocrinologist Herbert McLean Evans. Together, they published a monograph on the vital staining of connective tissue cells. The discovery of Vitamin E came as a result of the study of the reproductive cycle of rats. After establishing a standard diet for the rats to maintain their regular reproductive cycle, Bishop and Evans started experimenting with dietary deficiencies. In 1923, they found a previously unknown factor that is vital for reproduction. When the rats were fed with a diet where lard was the only source of fat, though they grew healthily, the female rats were unable to carry babies full term due to the breakdown of the placentas, and the male rats became sterile since the sperm-forming cells in the testes would deteriorate. Initially called "Factor X", Bishop and Evans narrowed down that this factor came from the lipid extract of lettuce and wheat germ. The name "Vitamin E" later came after Vitamin D.

Later life From 1924 to 1929, Bishop worked as a histopathologist at the George Williams Hooper Foundation for Medical Research in San Francisco. After her marriage and birth of her two daughters, she spent two years studying public health at the University of California Medical School. In mid-1930s, Bishop became a practicing physician and anesthesiologist at St. Luke's Hospital in San Francisco. She accepted a position at Alta Bates Hospital in Berkeley, California in 1940, and worked there until her retirement in 1953. She died at home in Berkeley in 1975.

Worked examples

Example 1 — a first encounter with Katharine Bishop

Start with the simplest possible case. Write down what Katharine Bishop 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 Katharine Bishop 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 Katharine Bishop 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 Katharine Bishop

In research: Katharine Bishop 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 Katharine Bishop 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: Katharine Bishop is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1889 births, 1975 deaths, 20th-century American women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Katharine Bishop 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.
