Mad Gasser of Mattoon

Mad Gasser of Mattoon is a chemistry 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 Mad Gasser of Mattoon rather than just read about it. In short: The Mad Gasser of Mattoon (also known as the Phantom Anesthetist, or simply the Mad Gasser) was the name given to an event of alleged mass hysteria in which a person or people allegedly committed a series of apparent gas attacks in Mattoon, Illinois, during the mid-1940s. More than two dozen separate cases of gassings were reported to police over the span of two weeks, in addition to many more reported sightings of…

Key takeaways

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

Reference excerpt

The Mad Gasser of Mattoon (also known as the Phantom Anesthetist, or simply the Mad Gasser) was the name given to an event of alleged mass hysteria in which a person or people allegedly committed a series of apparent gas attacks in Mattoon, Illinois, during the mid-1940s. More than two dozen separate cases of gassings were reported to police over the span of two weeks, in addition to many more reported sightings of the suspected assailant. The gasser's supposed victims reported smelling strange odors in their homes which were soon followed by symptoms such as paralysis of the legs, coughing, nausea and vomiting. No one died or had serious medical consequences as a result of the gas attacks. Police remained skeptical of the accounts throughout the entire incident. Many reported gassings had simple explanations, such as spilled nail polish or odors emanating from animals or local factories. Victims made quick recoveries from their symptoms and suffered no long-term effects. Nevertheless, local newspapers ran alarmist articles about the reported attacks and treated the accounts as fact. Although the explanation that the reports were only a case of mass hysteria is widely accepted, others maintain that a Mad Gasser actually existed.

Descriptions Most contemporary descriptions of the Mad Gasser are based on the testimony of Mr. Bert Kearney of 1408 Marshall Avenue, the husband of the victim of the first Mattoon case to be reported by the media. His wife, who was the one claiming to be attacked, did not describe seeing a prowler. He described the gasser as being a tall, thin man dressed in dark clothing and wearing a tight-fitting cap. Another report, made some weeks later, described the gasser as being a female dressed as a man. The Gasser had also been described as carrying a flit gun, an agricultural tool for spraying pesticide, which he purportedly used to expel the gas.

Worked examples

Example 1 — a first encounter with Mad Gasser of Mattoon

Start with the simplest possible case. Write down what Mad Gasser of Mattoon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Mad Gasser of Mattoon 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 Mad Gasser of Mattoon 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 Mad Gasser of Mattoon

In research
Mad Gasser of Mattoon appears in chemistry 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 Mad Gasser of Mattoon 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
Mad Gasser of Mattoon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 in Illinois, American people whose existence is disputed, American urban legends, so understanding it makes those chapters shorter.
In everyday life
Look for Mad Gasser of Mattoon 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.
