![]() Sir David Gill |
death Sir David Gill Died 24 Jan 1914 at age 70 (born 12 Jun 1843). Scottish astronomer known for his measurements of solar and stellar parallax, showing the distances of the Sun and other stars from Earth, and for his early use of photography in mapping the heavens. His early training in timekeeping as a watchmaker led to astronomy and he designed, equipped, and operated a private observatory near Aberdeen. To determine parallaxes, he perfected the use of the heliometer, a telescope that uses a split image to measure the angular separation of celestial bodies. In 1877, Gill and his wife measured the solar parallax by observing Mars from Ascension Island. He was appointed Her Majesty's Astronomer at the Cape of Good Hope (1879-1906). Gill also made geodetic surveys of South Africa. In fact he carried out all of the observations to measure the distances to stars in terms of the standard meter. His precise redetermination of the solar parallax was used for almanacs until 1968. |

birth Sir Alan Hodgkin Born 5 Feb 1914; died 20 Dec 1998 at age 84. Alan Lloyd Hodgkin was an English physiologist and biophysicist who shared (with his countryman Sir Andrew Huxley and Australian scientist Sir John Eccles) the Nobel Prize for Physiology or Medicine in 1963, for the discovery of the chemical processes involved in nerve conduction, more specifically, discoveries concerning the ionic mechanisms involved in excitation and inhibition in the peripheral and central portions of the nerve cell membrane. Hodgkin and Huxley performed their work on the so-called giant axon of Atlantic squid, Loligo pealei, which enabled them to record ionic currents, which would otherwise have not been possible in almost any other neuron, such cells being too small to study by the techniques of the time. |

death John Henry Poynting Died 30 Mar 1914 at age 61 (born 9 Sep 1852). British physicist who introduced a theorem (1884-85) that assigns a value to the rate of flow of electromagnetic energy known as the Poynting vector, introduced in his paper On the Transfer of Energy in the Electromagnetic Field (1884). In this he showed that the flow of energy at a point can be expressed by a simple formula in terms of the electric and magnetic forces at that point. He determined the mean density of the Earth (1891) and made a determination of the gravitational constant (1893) using accurate torsion balances. He was also the first to suggest, in 1903, the existence of the effect of radiation from the Sun that causes smaller particles in orbit about the Sun to spiral close and eventually plunge in. |

birth Max Ferdinand Perutz Born 19 May 1914; died 6 Feb 2002 at age 87. Austrian-British biochemist who shared the 1962 Nobel Prize for Chemistry for his X-ray diffraction analysis of the structure of haemoglobin, the protein that transports oxygen from the lungs to the tissues via blood cells. He identified that haemoglobin is constructed of four protein chains wound together, and that the molecule changes shape when oxygen is added. Perutz was also interested in studying glaciers, making measurements which were the first to show different rates of flow in different parts of the same glacier. |

![]() Goddard's first rocket patent |
Goddard's first rocket patent In 1914, Robert Goddard, age 31, was issued a U.S. patent, the first of the 214 he would obtain in his lifetime as a pioneer rocket scientist. This patent was for a “Rocket Apparatus” (U.S. No. 1,102,653) which described the multi-stage rocket concept. A liquid-fueled rocket design was issued a patent the following week, on 14 Jul 1914, also titled “Rocket Apparatus.” It described a combustion chamber, with expander nozzle, into which liquid fuels are pumped. This was his second rocket patent. On 16 Mar 1926, his test launch, the first ever of a liquid-fuelled rocket, managed to propel a 10-ft long projectile to a height of 41-ft (12.5 m). Its 2.5 second flight covered a distance of 184-ft at an average speed of 60-mph. The fuel was a combination of liquid oxygen and gasoline. |

![]() Gavin Maxwell |
birth Gavin Maxwell Born 15 Jul 1914; died 7 Sep 1969 at age 55. Scottish naturalist and author best known for his book Ring of Bright Water (1960), the story of his life in the western Highlands of Scotland with two pet otters. In 1945, he bought the small Hebridean island of Soay, to create a shark fishery there, but his effort was undercapitalized and failed. He found the sharks elusive, difficult to land in a small boat and he underestimated the refrigeration capacity required to keep the stored meat edible. However, the experience became the source for his book Harpoon Venture (1952). His later enterprises included encouraging Eider Ducks to breed on the small island of Eilean Dudh so that the down from their nests could be harvested, and establishing a collection of wild animals indigenous to Scotland to create a private zoo. |

![]() Transcontinental phone call |
Transcontinental phone call In 1914, transcontinental telephone service began. It was celebrated with a telephone conversation between Thomas A. Watson in San Francisco and Alexander Graham Bell in New York City repeating their historic conversation from 1876. Wendover, Utah, was the site of the completion of the first transcontinental telephone line in 1914. The day's state-of-the-art in signal transmission technology, loading coils, had reached its limit, barely able to deliver a faint voice from New York to Denver until Western Electric's high-vacuum tube for amplifying sound in telephone cables was developed in 1913. |

birth Baron Marcel Bich Born 29 Jul 1914; died 30 May 1994 at age 79. French inventor who built his business empire by creating throwaway Bic pens, razors and lighters. In 1945, Marcel Bich and his friend, Edouard Buffard, acquired an empty factory shell near Paris, France, and soon developed a thriving business, producing parts for fountain pens and mechanical lead pencils. Later, Bich spent two years developing his ballpoint pen design, and in 1949, he was able to produce a reliable, low cost ballpoint pen. In 1973 the Bic Lighter was introduced in the U.S., followed by Bic Shavers, first introduced in 1976 |

![]() Robert S. Dietz |
birth Robert S. Dietz Born 14 Sep 1914; died 19 May 1995 at age 80. Robert Sinclair Dietz was an American geophysicist and oceanographer who set forth a theory (1961) of seafloor spreading (a term he coined), in which new crustal material continually upwells from the Earth's depths along the mid-ocean ridges and spreads outward at a rate of several inches per year. While a student Dietz identified the Kentland structure in Indiana as a meteoric impact site. His professors steered him toward marine geology. He became the founder and director of the Sea Floor Studies Section at the Naval Electronics Laboratory (1946-1963). He also achieved prominence by studying meteorite craters, both on Earth and on the moon and arguing that these impact craters were common. He died of a heart attack. |

![]() Gas mask |
Gas mask In 1914, Garrett Morgan invented and patented a gas mask, a breathing device consisting of a canvas hood placed over the head. A double tube extended from the hood and merged into a single tube at the back. The open end held a sponge soaked with water to filter out smoke and to cool incoming air. On 25 Jul 1916, Morgan made national news for using the gas mask to recover several men trapped after an explosion in a new waterworks tunnel beneath Lake Erie at Cleveland, Ohio. After the rescue, Morgan's company received requests from fire departments around the country who wished to purchase the new masks. The Morgan gas mask was later refined for use by U.S. Army during World War I. One of Morgan's other inventions was an early traffic signal (patented in 1923). |

![]() Thyroxine |
Thyroxine In 1914, the thyroid hormone, thyroxine, was first crystallized by biochemist Edward C. Kendall of the Mayo Foundation in Rochester, NY. Thyroxine controls the cellular rate of carbohydrate metabolism and of protein synthesis and breakdown. On Dec 23, he began evaporating an ethanol solution of a sample of the acid-insoluble fraction of thyroid glands removed surgically from patients. It left a white crust surrounded by a ring of yellow waxy material. Adding ethanol now redissolved the waxy material, but not the white crust. On Christmas Day, he dissolved some of the white crust in ethanol and sodium hydroxide. A few drops of acetic acid precipitated crystals. This throxine was fully active in relieving the symptoms of thyroid deficiency in hypothyroid patients. |
