File:Richard Mead.jpg|link=Richard Mead (nonfiction)|1673: Physician and astrologer [[Richard Mead (nonfiction)|Richard Mead]] born.  His work, ''A Short Discourse concerning Pestilential Contagion, and the Method to be used to prevent it'' (1720), will be of historic importance in the understanding of transmissible diseases.
 
||1797: George Shillibeer born ... pioneer of omnibuses. Having founded a coach-building enterprise in Paris (1825), he expanded to include buses. On 4 Jul 1829, he commenced the first regular bus service from London to Paddington, carrying up to 20 passengers and in a coach drawn by three horses. Shillibeer adopted the word omnibus. He boasted it offered a safer and more comfortable ride than ordinary stagecoaches, since all passengers would ride inside. He was followed by imitators then more competition from the discovery that a trolley running on tracks could pull twice the payload. Although Shillibeer had revolutionized London's transport, he went bankrupt and spent time in debtors' prison. He eventually converted his omnibuses into "Shillibeer's Funeral Coaches". Pic.
 
||1799: Joachim Barrande ... geologist and paleontologist. He settled in Prague (1832), at first as an engineer. While surveying the proposed route for a horse-drawn railway, he became interested in the local fossil-bearing rocks there. From 1840, he turned to the study of these fossils in the strata of the central Bohemian basin. In his lifetime, he gathered some 3500 species of graptolites, brachiopoda, mollusca, trilobites and fishes, showing a wide variety of life forms in the Early Paleozoic era. (The Paleozoic era spanned 540-245 million years ago.) He meticulously recorded his findings in Système silurien du centre de la Bohême, which remains a fine reference work. The first volume was published in 1852, and was followed by 20 more in his lifetime. He opposed Darwin's theory of evolution, instead advocating the theory of catastrophes. Pic.
 
||1829: Mathematician and academic Norman Macleod Ferrers born. In 1871 he first suggested to extend the equations of motion with nonholonomic constraints. His another treatise on "Spherical Harmonics," published in 1877, presented many original features. In 1881 he studied Kelvin's investigation of the law of distribution of electricity in equilibrium on an uninfluenced spherical bowl and made the addition of finding the potential at any point of space in zonal harmonics. Pic.

||1851: Lorenz Oken dies ... German naturalist who offered early evolutionary ideas and stimulated comparative anatomy. He theorized (incorrectly) that the skull was a modified vertebra, but formed some fundamental concepts which stimulated further thought from later scientists. In Die Zeugung, he discussed “the infusoria”—elementary units of living organisms—into which all flesh can be broken down. Higher animals, he proposed, consisted of constituent animalcules. Entities, whether plants or animals, became organisms by the fusion of these primal animals. Those elements lose all individuality and create a higher unity. Lorenz Oken wrote many books on natural history for students and adults, founded a scholarly journal (contributing most of its articles), and organized scientific congresses. Pic.

||1860 – Ottó Bláthy, Hungarian engineer and chess player (d. 1939). Pic.
||1871: An explosion at the factory of Patent Gun Cotton Company, Stowmarket, Suffolk, England, killed 24 people and injured many more It happened in the early afternoon, devastating the factory and left a crater 100-ft long and 10-ft deep. Windows were blown in all over Stowmarket ands roofs damaged, and the explosion was heard up to ten miles away. It was the biggest disaster ever to hit the town. The inquest found that it had probably been caused by sabotage but no one was ever brought to trial. It has been suggested that the findings were a whitewash which helped prevent any criticism falling on the heads of the factory or the inventor of the process. (Guncotton was first patented by Christian Frederick Schönbein in 1846.)
 
||1860: Ottó Bláthy born ... engineer and chess player ... co-inventor of the modern electric transformer, the tension regulator, the AC watt-hour meter, motor capacitor for the single-phase (AC) electric motor, the turbo generator, and the high-efficiency turbo generator. Pic.

||1896: The first U.S. patent for an electric light bulb socket featuring an on-and-off pull chain was issued to Harvey Hubbell of Bridgeport, Connecticut (No. 565,541). On 8 Nov 1904, he patented a separable electric plug (No. 774250) adapting an Edison screw socket to a flat prong style. His inventions are now familiar throughout North America. His manufacturing company, Harvey Hubbell Inc. still exists today.
||1903: The first U.S. patent for instant coffee was issued to Satori Kato of Chicago, Illinois. It was entitled "Coffee Concentrate and Process of Making Same" (No. 735,777). The application was filed 17 Apr 1901, in which year his Kato Coffee Company introduced the product at the Pam-American Exposition in Buffalo. Two years earlier, four men had formed the company when an American coffee importer and a roaster contacted Sartori Kato (the Japanese inventor of a soluble tea), who adapted his process of dehydration to coffee, with the assistance of an American chemist.

||1909: The liner S.S. Arapahoe was the first ship to use the S.O.S. radio distress call. Its wireless operator, T. D. Haubner, radioed for help after a propeller shafat snapped while off the coast at Cape Hatteras, North Carolina, USA. The call was heard by the United Wireless station “HA” at Hatteras. A few months later, Haubner on the S.S. Arapahoe received an SOS from the SS Iroquois, the second use of SOS in America. Previously, the distress code CQD had been in use as a maritime distress call, standardised by the Marconi Wireless Telegraph Co. in 1904. The second International Radio Telegraphic Convention (1906) proposed the alternative SOS for its distinctive sound. It was ratified as an international standard in 1908.

Eighteen months after Yury Gagarin became the first man in space, Nikolayev became Russia's third cosmonaut to travel into space. Pavel Popovich was launched in Vostok IV the next day. The pair made the first simultaneous flights; both returned on 15 Aug. Nikolayev's flight set an endurance record, circling the Earth 64 times in 96 hours, having completed 1,650,000 miles. He returned to space in 1970 for his second and final mission on the Soyuz 9 craft, setting a new endurance record, spending 18 days in space in Soyuz 9.
