The core or center may be an ice cream, sherbet, sorbet, ice, or other material congealed by refrigeration." The shell was described as "like that used in coating chocolate candies, although preferably modified to harden at a lower temperature," and not too brittle. |

![]() Sir Patrick Manson |
death Sir Patrick Manson Died 9 Apr 1922 at age 77 (born 3 Oct 1844). Scottish physician and parasitologist who has been called the “father of tropical medicine.” He was the first to identify an insect for the spread of infection (1877-79). While working at Amoy, China, he found the development phase of filaria worms in the tissues of blood-sucking mosquitoes. This parasite worm causes the filariasis disease when transferred to human body tissues. In 1894, he proposed a mosquito-malaria hypothesis. Manson moved to Hong Kong (1883-89), where he set up a medical school. In 1886 he co-founded Dairy Farm to produce contamination-free cows' milk. He also researched sleeping sickness and beri-beri, and helped introduce vaccination to the Chinese. He inspired Alphonse Laveran's discovery of the malarial parasite, and Sir Ronald Ross's proof of transmission of malaria by Anopheles mosquitoes. |

![]() Leon M. Lederman |
birth Leon M. Lederman Born 15 Jul 1922. Leon Max Lederman is an American physicist who, along with Melvin Schwartz and Jack Steinberger, received the Nobel Prize for Physics in1988 for their joint research and discovery (1960-62) of a new subatomic particle, the muon neutrino. Neutrinos are subatomic particles having no detectable mass and no electric charge, which travel at the speed of light. The discovery of muon neutrinos, a new type of neutrino, was followed by discoveries by other scientists of a number of different “families” of subatomic particle. Together, they now form a standard model, a scheme that has been used to classify all known elementary particles. He was director of the Fermi National Accelerator Laboratory in Batavia, Ill. (1979-89). |

![]() Thomas S. Kuhn |
birth Thomas S. Kuhn Born 18 Jul 1922; died 17 Jun 1996 at age 73. Thomas Samuel Kuhn was an American science historian and science philosopher was a MIT professor, noted for his highly influential The Structure of Scientific Revolutions (1962). He held that science was not a steady, cumulative acquisition of knowledge, but it is “a series of peaceful interludes punctuated by intellectually violent revolutions.” Then appears a Lavoisier or an Einstein, often a young scientist not indoctrinated in the accepted theories, to sweep the old paradigm away. Such revolutions, he said, came only after long periods of tradition-bound normal science. He pointed out that scientific research and thought are defined by “paradigms,” or trusted theories, concepts, methods and experiments. Such paradigms are accepted by scientists, who continue to extend, refine, explain and measure results until they meet an problem that cannot be resolved within the established framework. Such anomaly or contradiction eventually requires an intellectual revolution, such as the paradigm shifts from Ptolemaic cosmology to Copernican heliocentrism. “Frameworks must be lived with and explored before they can be broken.” |

![]() Edward Anthony Spitzka |
death Edward Anthony Spitzka Died 4 Sep 1922 at age 46 (born 17 Jun 1876). American anatomist and brain morphologist who assisted at the autopsy (29 Oct 1901) of the brain of Leon Franz Czolgosz, the assassin of U.S. president William McKinley. At the time, he had just published an exhaustive series of eight papers on the human brain, but was only in the fourth year of his medical training. Although he detected a few very minor variations in gyri and sulci patterns in the brain of Czolgosz, he reported in the New York Medical Journal (1902) that “nothing has been found in the brain of this assassin that would condone his crime.” He became editor of, and revised, American editions of Gray's Anatomy. Throughout his career he studied the brain morphology of groups of famous people, different races, and criminals, thought ultimately he was unable to link traits to brain structure. |

![]() Telephone fax |
Telephone fax In 1922, city telephone lines were used for the first time in the U.S. for the transmission of a facsimile photo in Washington, DC. Charles F. Jenkins sent an image from 1519 Connecticut Ave to the U.S. Navy Radio Staion NOF at Anacostia, D.C. Witnesses from the U.S.Navy and the Post Office Dept. attended the transmission. A photographic plate was used to record the signals at 5502 16th St, N.W. Washington, D.C. Earlier in the year, on 11 Jun 1922, a photograph had been sent by radio across the Atlantic from Rome to Bar Harbor, Maine. That transmission reproduced a 7 x 9.5 in. halftone picture, using light falling on a selenium cell to form the dots. |

![]() Max Abraham |
death Max Abraham Died 16 Nov 1922 at age 47 (born 26 Mar 1875). German physicist whose life work was almost all related to Maxwell's theory. The text he wrote was the standard work on electrodynamics in Germany for a long time. Throughout his life, he remained strongly opposed to Einstein's Theory of Relativity, objecting to its postulates which he felt were contrary to classical common sense. He further held that the experimental evidence did not support that theory. In 1902, he had developed a theory of the electron in which he held that an electron was a perfectly rigid sphere with a charge distributed evenly over its surface. He also believed in the ether theory, thought that future astronomical data would validate it, and thus relativity was not in fact a good description of the real world. |

![]() Stanley Keith Runcorn |
birth Stanley Keith Runcorn Born 19 Nov 1922; died 5 Dec 1995 at age 73. British geophysicist Southport, Lancashire, who was the first to discover evidence of the periodic polar reversals of the Earth's magnetic field. In the 1950s he was a pioneer in the fledgling discipline of paleomagnetism, or remanent magnetism, the study of the residual magnetism. He also made substantial contributions to various fields, including convection in the Earth and Moon, the shape and magnetic fields of the Moon and planets, magnetohydrodynamics of the Earth's core, earth currents, changes in the length of the day and polar wandering, continental drift and plate tectonics. He was murdered, aged 73, when he disturbed a thief in his motel room in San Diego, while on a US lecture tour. |

![]() Yuri Valentinovich Knorozov |
birth Yuri Valentinovich Knorozov Born 19 Nov 1922; died 31 Mar 1999 at age 76. Russian linguist, epigraphist, and ethnologist who played a major role in the decipherment of Mayan hieroglyphic writing. Remarkably, though not permitted to leave the Soviet Union during the post-war decades he focused on the Mayan language, Knorozov still managed to decipher the phonetic code of the pre-Columbian society on the Mexican peninsula. Others before him had tried to "read" Maya glyphs without success, because they tried to interpret them in terms of an alphabet. Knorozov instead advocated phoneticisms. He realized that the purported alphabet represented a part of the Maya syllabary, and then identified many of the syllabic marks, or glyphs, found on the many Mayan tombs and monuments. |

![]() John Wanamaker |
death John Wanamaker Died 12 Dec 1922 at age 84 (born 11 Jul 1838). American businessman who founded a department store and adopted new technology in his buildings for publicity. His “Grand Depot” was the first U.S. store to use electric arc lamps (26 Dec 1878) in Philadelphia, Pa. Wanamaker had a major ready-made men's clothing retail clothing business (opened 1861) when he bought (1875) the Pennsylvania Railroad depot for $500,000 and converted it into his innovative Grand Depot department store. The city's Centennial Exposition visitors boosted sales. It became one of the largest U.S. department stores. From 1885, the store was called "Wanamaker's". His stores were a base for experimental wireless from 1910, and in 1922, a radio broadcast station was opened in the store to initiate radio receiver sales. |
