24 Jan 1925 Solar eclipse movie	science	Solar eclipse movie In 1925, a motion picture of a solar eclipse was taken by the U.S. Navy from the dirigible Los Angeles. The craft was at an elevation of about 4,500-ft and positioned about 19 miles east of Montauk Point, Long Island, NY. This give a view of a total eclipse of the sun that lasted just over 2-min. Four astronomical cameras and a spectrograph were used as well as two moving picture cameras. This was the first time in the U.S. that a dirigible had been used as a platform for observation of a total eclipse of the sun. The first U.S. attempt to photograph one from an aircraft 10 Sep 1923 was unsuccesful due to cloudy conditions, but on 28 Apr 1930, a flight over California sponsored by the U.S. Naval Observatory recorded a total solar eclipse.

23 Feb 1925 Sir Thomas Edward Thorpe	science	death Sir Thomas Edward Thorpe Died 23 Feb 1925 at age 79 (born 8 Dec 1845). English chemist and author whose work in inorganic chemistry included the supervision of research into determining the presence of arsenic in beer and how to make pottery glazes without lead. In his early studies, while a chemistry student under Roscoe, he became a research assistant in his pioneering research work on vanadium, and the determination of its atomic weight. After graduation he worked first with Bunsen and then Kekulé. He then spent time teaching at the Royal College of Science, London (which became Imperial College). Later in life, he was director of the government laboratories (1894-1909). His research included study of phosphorus fluorides and oxides, in which he discovered the valence of five for phosphorus in phosphorus pentafluoride. As well as textbooks in chemistry, he wrote about chemistry history.

13 Apr 1925 Elwood Haynes	science	death Elwood Haynes Died 13 Apr 1925 at age 67 (born 14 Oct 1857). American inventor who built one of the first successful gasoline-powered automobiles. In 1886, when natural gas was found in his hometown of Portland, Indiana, Haynes organized a company to supply it to the town. He devised a method to dehydrate the gas prior to its being pumped through the lines. Also in 1886, he invented a small vapor thermostat used on natural gas. In 1893, he purchased a gasoline engine and designed a "horseless carriage." When Haynes was searching for an alloy that would make a durable spark plug electrode, he invented stellite alloy, which invention is still contributing to society today. Harder than steel and resistant to corrosion, this metal now plays an important part in fabrication of aeronautical materials suitable for exploration of outer space.

10 May 1925 Scopes hearing	science	Scopes hearing In 1925, John T. Scopes was given a preliminary hearing before three judges. He had been arrested and charged under a new Tennessee's state law, the Butler Act, which prohibited the teaching of Darwin's theory of evolution in public schools. Scopes had agreed to participate in a challenge to that law, with the support of local leaders in Dayton, Tennessee, and the American Civil Liberties Union. A few weeks later, on 10 Jul 1925, the trial began, which became known as the “Scope's Monkey Trial”. At its end, on 25 Jul 1925, he was found guilty and fined $100. Although upon appeal the fine was ruled excessive and over-ruled, the state law itself was not found unconstitutional. Thereafter, the law was not enforced, but it was not repealed until 42 years later, on 17 May 1967.

25 Dec 1925 Karl Abraham	science	death Karl Abraham Died 25 Dec 1925 at age 48 (born 3 May 1877). German psychoanalyst who studied who studied the role of childhood sexual trauma in relation to the symptoms of mental illness. He was initiated into psychoanalysis by Carl Gustav Jung (1904). He first met Sigmund Freud in 1907, and subsequently became one of his most reliable collaborators. Covering a wide range, Abraham's papers include work on depression, mania, auto erotism, repressed hate, as well as others on applied psychoanalysis that include papers on the Day of Atonement and a major one (1909) in which he connected myths with dreams and viewed both as wish-fulfillment fantasies. Abraham founded the Berlin Psychoanalytic Society (1910). He made pioneering efforts in the psychoanalytic treatment of manic- depressive psychosis.
