Francis Joseph McCarty
Francis Joseph McCarty (May 23, 1888 – May 11, 1906) was a San Francisco experimenter, who conducted early radiotelephone research and development. He died at the age of 17, but despite his young age and early death, in 2011 he was elected into the Bay Area Radio Hall of Fame, recognized as being one of the "pioneers of broadcasting in the Bay Area". Biography Francis Joseph McCarty was born in San Francisco, California in 1888 to John Henry McCarty and Catherine Lynch. His sister, Mary Eunice McCarthy (who used a different spelling of the family name), reported in a memoir that at the age of thirteen Francis received permission to drop out of school, having found most of the curriculum a distraction to his desire to become an inventor. With the assistance of one of the Jesuit professors at the local St. Ignatius school that he had been attending, McCarty developed his own routine of independent study. At this time radio transmissions (then commonly known as "wireless telegr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry McCarty (filmmaker)
Billy the Kid (born Henry McCarty; September 17 or November 23, 1859July 14, 1881), also known by the pseudonym William H. Bonney, was an outlaw and gunfighter of the American Old West, who killed eight men before he was shot and killed at the age of 21. He also fought in New Mexico's Lincoln County War, during which he allegedly committed three murders. McCarty was orphaned at the age of 15. His first arrest was for stealing food at the age of 16 in 1875. Ten days later, he robbed a Chinese laundry and was arrested again but escaped shortly afterwards. He fled from New Mexico Territory into neighboring Arizona Territory, making himself both an outlaw and a federal fugitive. In 1877, he began to call himself "William H. Bonney". Two versions of a wanted poster dated September 23, 1875 referred to him as "Wm. Wright, better known as Billy the Kid". After killing a blacksmith during an altercation in August 1877, McCarty became a wanted man in Arizona and returned to New M ...

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cliff House, San Francisco
The Cliff House is a neo-classical style building perched on the headland above the cliffs just north of Ocean Beach, in the Outer Richmond neighborhood of San Francisco, California. The building overlooks the site of the Sutro Baths ruins, Seal Rocks, and is part of the Golden Gate National Recreation Area, operated by the National Park Service (NPS). The Cliff House is owned by the NPS; the building's terrace hosts a room-sized camera obscura. For most of the Cliff House's history, since 1863, the building's main draw has been restaurants and bars where patrons could enjoy the Pacific Ocean views. Since 1977, these restaurants and bars have been run by a private operator under contract with the National Park Service. In December 2020, the 47-year operator of these amenities announced that it was closing, and it criticized the NPS for not having signed a new long-term lease with any operator since its own prior 20-year lease had expired in June 2018. Dozens of ships have run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1906 San Francisco Earthquake
At 05:12 Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (''Extreme''). High-intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died, and over 80% of the city was destroyed. The events are remembered as one of the worst and deadliest earthquakes in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high on the lists of American disasters. Tectonic setting The San Andreas Fault is a continental transform fault that forms part of the tectonic boundary between the Pacific Plate and the North American Plate. The strike-slip fault is characterized by ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyril Frank Elwell
Cyril Frank Elwell (August 20, 1884 – 1963) was an Australian-bornHugh G.J. Aitken, ''The Continuous Wave: Technology and American Radio, 1900-1932'' Princeton University Press, 2014, Chapter 3 ''Elwell, Fuller and the Arc'' American inventor and pioneer in development of radio. He had an American father and a German mother, then went to Fort St. Model Public School in Sydney, Australia. Elwell arrived in the United States in 1902. He applied to Stanford University and entered the electrical engineering program there. In 1906, he organized fellow students to participate in repairs at the campus, owing to the San Francisco earthquake. He graduated in 1907. He founded the Poulsen Wireless Telephone and Telegraph Company, later renamed Federal Telegraph Company in 1909. Elwell designed a large transformer for electric arc furnace reduction of iron ore; this became the topic of his thesis. He had published some technical papers on applications in electric metallurgy. In 1908 he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valdemar Poulsen
Valdemar Poulsen (23 November 1869 – 23 July 1942) was a Danish engineer who made significant contributions to early radio technology. He developed a magnetic wire recorder called the telegraphone in 1898 and the first continuous wave radio transmitter, the Poulsen arc transmitter, in 1903, which was used in some of the first broadcasting stations until the early 1920s. Early life Poulsen was born on 23 November 1869 in Copenhagen. He was the son of the Supreme Court judge Jonas Nicolai Johannes Poulsen and Rebekka Magdalene (née Brandt). Recording innovations The magnetic recording was demonstrated in principle as early as 1898 by Poulsen in his telegraphone. Magnetic wire recording, and its successor, magnetic tape recording, involve the use of a magnetizable medium which moves past a recording head. An electrical signal, which is analogous to the sound that is to be recorded, is fed to the recording head, inducing a pattern of magnetization similar to the signal. A p ...
