On 4 Jun 1906, pathologist Howard T. Ricketts discovered that Rocky Mountain Spotted Fever is caused by an unusual microbe spread by ticks. Its symptoms are similar to typhus except the rash starts at extremities and moves to the trunk. The disease causes high morbidity with about 70% of cases requiring hospitalization, without which, the untreated mortality rate is about 7% of cases.

He published a paper, Rocky Mountain Spotted Fever which summarized his investigations into the nature and means and transmission of the disease. It is well worth finding out about his careful work by reading this report, given in his own words.


Book of the Day
The Remarkable Life of William Beebe: Explorer and Naturalist

On 4 Jun 1962, Charles William Beebe died, an American biologist whose lust for exploration took him to remarkable depths in the ocean, through the mountains and jungles of the Far East, and on studies of the complex ecology of the tropics. Today's book pick is: The Remarkable Life of William Beebe: Explorer and Naturalist, by Carol Grant Gould, who makes Beebe's biography read like a riveting adventure. Not surprising since his insatiable curiosity for natural world took him on such trips from the Galapagos Islands, to the jungles of British Guiana, from the comfort of the Bronx Zoo to the breath-taking danger of the previously unfathomed depths of the ocean in a four-foot diameter bathysphere of his own invention. This vibrant biography of a great naturalist gives him the recognition he deserves for his trailblazing work in environmental science.

It is available from Amazon, typically about New from $96.05. Used from $44.99. (As of earlier time of writing - subject to change.)


Quotations for Today
Thumbnail of William Thomas Astbury
We are at the dawn of a new era, the era of “molecular biology” as I like to call it, and there is an urgency about the need for more intensive application of physics and chemistry, and specially of structure analysis, that is still not sufficiently appreciated.
— William Thomas Astbury, English physical biochemist (died 4 Jun 1961). quote icon

Gifford Pinchot points out that in colonial and pioneer days the forest was a foe and an obstacle to the settler. It had to be cleared away... But [now] as a nation we have not yet come to have a proper respect for the forest and to regard it as an indispensable part of our resources—one which is easily destroyed but difficult to replace; one which confers great benefits while it endures, but whose disappearance is accompanied by a train of evil consequences not readily foreseen and positively irreparable.
— Eliot Blackwelder, American geologist (born 4 Jun 1880). quote icon

The beauty and genius of a work of art may be reconceived, though its first material expression be destroyed; a vanished harmony may yet again inspire the composer, but when the last individual of a race of living things breathes no more, another heaven and another earth must pass before such a one can be again.
— William Beebe, American biologist, explorer and writer (died 4 Jun 1962). quote icon

Births

On 4 Jun 1910, the inventor of the hovercraft was born. He began by testing the concept using kitchen scales, tin cans and a vacuum cleaner. The next year he built a working balsa wood model with a model-aircraft engine. The first full-scale prototype, SR-N1, weighed 7 tons and was capable of 60 knots. It crossed the English Channel in 1959 (with the inventor aboard). Hovercraft entered regular cross-channel service in 1968.

Beno Gutenberg was born 4 Jun 1889, an American seismologist noted for his analyses of earthquake waves and the information they furnish about the physical properties of the Earth’s interior. When he worked with Charles Richter, they developed a method of determining the intensity of earthquakes. Calculating the energy released by present-day shallow earthquakes, they showed that three-quarters of that energy occurs in a particular geographical region.
Where is this geographic region?

William Beebe (1877-1962) was an American biologist, explorer, and writer on natural history. As director of tropical research for the New York Zoological Society from 1919, he led scientific expeditions to many parts of the world. He was the co-inventor of the bathysphere, a spherical diving-vessel for use in underwater observations. In 1934, with Otis Barton, he descended in his bathysphere to a then record depth.
To the nearest thousand feet, how deep was this record dive?

On 4 Jun 1984, the cloning of DNA sequences from an extinct animal was reported. Using samples from an over 140-yr-old hide in a German museum, three Berkeley scientists managed to extract enough DNA from the animal’s flesh to determine some of its sequences of “base pairs” Despite degradation fragmenting the DNA molecule, the scientists could show this animal was more closely related to the zebra than the horse.

In 1963, a U.S. patent for a “Toy Truck” (No. 3,091,888) was issued. The toy separated into a chassis, driver's cab, truck body, wheels and four axles so it could be reassembled in either as a closed van body or a dump truck form. The inventor was not yet an adult
