07 Jul 1930 Boulder Dam construction begins	science	Boulder Dam construction begins In 1930, construction began on the site infrastructure for construction of Boulder Dam (Hoover Dam). What had taken decades to come to a political resolution, took only five years more to become a reality. It took the labour of 21,000 men to produce what is now the second-highest dam in the country. The concrete gravity-arch dam on the Colorado River bewteen Nevada and Arizona, impounds Lake Mead, the largest U.S. reservioir. It generates electricity, supplies water to California cities and irrigation to support farming, as well as flood control. Bids for construction were opened on 11 Mar 1931, and awarded to Six Companies, Inc., for $48,890,995. On 6 Jun 1933, the first concrete was poured. It was dedicated on 30 Sep 1935, by President Franklin D. Roosevelt.
07 Jul 1930 Sir Arthur Conan Doyle	science	death Sir Arthur Conan Doyle Died 7 Jul 1930 at age 71 (born 22 May 1859). Scottish author and physician whose fictional detective, Sherlock Holmes, emulates the scientist, diligently searching through data and to make sense of it. “It is a capital mistake to theorize before one has data.” His medical degree was awarded at the University of Edinburgh, where he studied under noted surgeon Joseph Bell. After serving as the doctor on an Arctic whaling ship, he practiced in England for a short time as a physician, with little income. So he turned to writing. He was active as a social reformer, and spoke to the Committee on the Daylight Saving Bill in 1908 advocating its adoption. Later in life he was a convert to spiritualism, and requested burial in an upright position in the garden of his home.
15 Jul 1930 Robert Ernest House	science	death Robert Ernest House Died 15 Jul 1930 at age 54 (born 3 Aug 1875). American physician who championed the use of scopolamine hydrobromide in criminology, which became known as a “truth serum.” Based on research into its use as a general birth anaesthetic by J. Christian Gauss, House interpreted from the results that a patient in the twilight state was unable to tell a lie. From 1924, House convinced Texas criminologists, to use the drug to “assist” in determination of guilt or innocence of a suspect. Later, it was found by legal challenges and CIA research in the 1950s that House's confidence was misplaced; its value was very much exaggerated. Any “truth” confessed under the drug's influence was distorted by the drug's halucinogenic side effects. Such use was ended. (Scopolamine is still used in minute doses to control motion sickness, and as a veterinary preanesthetic medication.
15 Jul 1930 Stephen Smale	science	birth Stephen Smale Born 15 Jul 1930. American mathematician who was awarded the Fields Medal in 1966 for his work in topology and dynamical systems. One of his studies (1961) was on the generalised Poincaré conjecture, a famous problem of 20th-century, which asserts that a simply connected closed 3-dimensional manifold is a 3-dimensional sphere. Smale proved a higher dimensional Poincaré conjecture for an n-dimensional manifold where n is at least 5. In other work, related to strange attractors, one of the early fractals to be studied known, he discovered strange attractors which lead to chaotic dynamical systems. (An attractor in classical mechanics is a geometrical way of describing the behaviour of a dynamical system.) His recent work has been on theoretical computer science.

01 Sep 1930 Peeter Põld	science	death Peeter Põld Peeter Põld (born 1878), Estonian politician and pedagogical scientist.
23 Sep 1930 Flashbulb patented	science	Flashbulb patented In 1930, Johann Ostermeyer of Athegnenber, Germany, patented his "Improvements in flash lights used for photographic purposes." (UK patent 324,578). The modern photographic safety flash bulb evolved from this design, which used aluminium wire or foil in oxygen. Unfortunately, all too frequently, these versions exploded! The flashbulb was introduced to the American market in 1930 by General Electric. Flash cubes came along in 1966, and the percussively ignitable "Magicube" in 1970.

05 Nov 1930 Christiaan Eijkman	science	death Christiaan Eijkman Christiaan Eijkman (born 1858), Dutch physiologist.
13 Nov 1930 Rotolactor	science	Rotolactor In 1930, the Rotolactor, invented by Henry W. Jeffries, was housed in the lactorium of the Walker Gordon Laboratory Company, Inc., at Plainsboro, N.J. This was a 50-stall revolving platform that enabled the milking of 1,680 cows in seven hours by rotating them into position with the milking machines. A Rotolactor was displayed at the 1939 New York World's Fair as part of the "Dairy World of Tomorrow," exhibit in the Borden building. The glass-enclosed revolving Rotolactor platform carried 150 pedigreed cows were washed, dried, and mechanically milked twice daily. A favorite attraction of the Food Zone, the Rotolactor epitomized how technology advanced the production of such a widely-used product as milk.

25 Nov 1930 pathologist	science	pathologist (medicine) Cecil George Paine, a pathologist at the Sheffield Royal Infirmary in England, achieves the first recorded cure (of an eye infection) using penicillin.
25 Dec 1930 Eugen Goldstein	science	death Eugen Goldstein Died 25 Dec 1930 at age 80 (born 5 Sep 1850). German physicist who discovered and named canal rays (1886) which emerge through holes in the anodes of low-pressure electrical discharge tubes (later shown to be positively charged particles). Earlier, he coined the term “cathode ray” (1876) emitted from a cathode. He was the first to see that they could cast a shadow, and were emitted at right angles to the surface. He also investigated the wavelengths of light emitted by metals and oxides when canal rays impinge on them. When the Berlin Urania, opened in 1889 it had five scientific departments and a “science theatre,” it was Goldstein who had recommended the “hall of physics in which the visitor could experiment on his own.” Students of his who continued his work included Wilhelm Wien and Johannes Stark.
