Key takeaways

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

Reference excerpt

John Franklin Enders (February 10, 1897 – September 8, 1985) was an American biomedical scientist and Nobel Laureate. Enders has been called "The Father of Modern Vaccines."

Life and education Enders was born in West Hartford, Connecticut, on February 10, 1897. His father, John Ostrom Enders, was CEO of the Hartford National Bank and left him a fortune of $19 million upon his death. He attended the Noah Webster School in Hartford, and graduated from St. Paul's School in Concord, New Hampshire in 1915. After attending Yale University a short time, he joined the United States Army Air Corps in 1918 as a flight instructor and a lieutenant. After returning from World War I, he graduated from Yale, where he was a member of Scroll and Key as well as Delta Kappa Epsilon. He went into real estate in 1922, and tried several careers before choosing the biomedical field with a focus on infectious diseases, gaining a PhD at Harvard in 1930. He later joined the faculty at Children's Hospital Boston. Enders died at his summer home in Waterford, Connecticut, aged 88, on 8 September 1985. His wife died in 2000.

Biomedical career In 1949, Enders, Thomas Huckle Weller, and Frederick Chapman Robbins reported successful in vitro culture of an animal virus—poliovirus. The three received the 1954 Nobel Prize in Physiology or Medicine "for their discovery of the ability of poliomyelitis viruses to grow in cultures of various types of tissue". Meanwhile, Jonas Salk applied the Enders-Weller-Robbins technique to produce large quantities of poliovirus, and then developed a polio vaccine in 1952. Upon the 1954 polio vaccine field trial, whose success Salk announced on the radio, Salk became a public hero but failed to credit the many other researchers that his effort rode upon, and was somewhat shunned by America's scientific establishment. In 1954, Enders and Thomas C. Peebles isolated measlesvirus from an 11-year-old boy, David Edmonston. Disappointed by polio vaccine's development and involvement in some cases of polio and death—what Enders attributed to Salk's technique—Enders began development of measles vaccine. In October 1960, an Enders team began trials on 1,500 intellectually disabled children in New York City and on 4,000 children in Nigeria. Refusing credit for merely himself when The New York Times announced the measles vaccine effective on September 17, 1961, Enders wrote to the newspaper to acknowledge the work of various colleagues and the collaborative nature of the research. In 1963, a deactivated measles vaccine and an attenuated measles vaccine were introduced by Pfizer and Merck & Co., respectively. He continued to work in virology research till the late 1970s and retired from the laboratory at the age of 80.

Worked examples

Example 1 — a first encounter with John Franklin Enders

Start with the simplest possible case. Write down what John Franklin Enders 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 John Franklin Enders 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 Franklin Enders 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 Franklin Enders

In research
John Franklin Enders 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 John Franklin Enders 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 Franklin Enders is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1897 births, 1985 deaths, American Nobel laureates, so understanding it makes those chapters shorter.
In everyday life
Look for John Franklin Enders 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.
