Reginald A. Fessenden House
The Reginald A. Fessenden House is a historic house in the village of Chestnut Hill in Newton, Massachusetts. It was the residence from 1919 to his death in 1932 of the inventor Reginald A. Fessenden (1866–1932), called "the father of radio broadcasting," because he was the first to broadcast the human voice and music by radio. The house was designated a National Historic Landmark in 1976 in recognition of Fessenden's accomplishments. Description and history The Fessenden House is an architecturally undistinguished three story brick building, with a stuccoed exterior and a tile roof. It has vernacular styling that includes a hooded entry, large central chimney, and a generally asymmetrical massing. The interior follows a fairly typical central hall plan. Both the exterior and interior of the house are relatively unaltered since Fessenden's ownership; the only notable alteration is the addition of awnings on some of the east-facing windows. Reginald A. Fessenden was born in Qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chestnut Hill, Massachusetts
Chestnut Hill is an affluent New England village located west of downtown Boston, Massachusetts, United States. Like all Massachusetts villages, Chestnut Hill is located within one or more incorporated municipal entities. It is located partially in Brookline in Norfolk County; partially in the Brighton neighborhood of the city of Boston in Suffolk County; partially in the West Roxbury neighborhood of the city of Boston in Suffolk County, and partially in the city of Newton in Middlesex County. Chestnut Hill's borders are defined by the 02467 ZIP Code. The name refers to several small hills that overlook the 135-acre (546,000 m2) Chestnut Hill Reservoir rather than one particular hill. Chestnut Hill is best known as the home of Boston College and as part of the Boston Marathon route. History The boundary between Newton and Brighton was originally more or less straight northwest–southeast, following today's boundary at the east edge of the Newton Commonwealth Golf Course ...

Spark-gap Transmitter
A spark-gap transmitter is an obsolete type of radio transmitter which generates radio waves by means of an electric spark."Radio Transmitters, Early" in Spark-gap transmitters were the first type of radio transmitter, and were the main type used during the wireless telegraphy or "spark" era, the first three decades of radio, from 1887 to the end of World War I. German physicist Heinrich Hertz built the first experimental spark-gap transmitters in 1887, with which he proved the existence of radio waves and studied their properties. A fundamental limitation of spark-gap transmitters is that they generate a series of brief transient pulses of radio waves called damped waves; they are unable to produce the continuous waves used to carry audio (sound) in modern AM or FM radio transmission. So spark-gap transmitters could not transmit audio, and instead transmitted information by radiotelegraphy; the operator switched the transmitter on and off with a telegraph key, creating pulses ...

List Of National Historic Landmarks In Massachusetts
The Commonwealth of Massachusetts has a total of 191 National Historic Landmarks (NHLs) within its borders. This is the second highest statewide total in the United States after New York, which has more than 250. Of the Massachusetts NHLs, 57 are in the state capital of Boston, and are listed separately. Ten of the remaining 134 designations were made when the NHL program was formally inaugurated on October 9, 1960; the most recent were in 2021. Cambridge is the city with the most NHLs outside Boston (at 19), and Middlesex County is home to 43 NHLs (again outside the 58 from Boston, which comprise all but two of the NHLs in Suffolk County). Every county in the state has at least one NHL ( Franklin County has exactly one, the Old Deerfield Historic District). The state's NHLs were chosen for a diversity of reasons. Some of the nation's oldest surviving structures are included: a number of 17th-century houses are listed, including the Fairbanks House (late 1630s) of Dedha ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wireless Telegraphy
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newton, Massachusetts
Newton is a city in Middlesex County, Massachusetts, United States. It is approximately west of downtown Boston. Newton resembles a patchwork of thirteen villages, without a city center. According to the 2020 U.S. Census, the population of Newton was 88,923. History Newton was settled in 1630 as part of "the newe towne", which was renamed Cambridge in 1638. Roxbury minister John Eliot persuaded the Native American people of Nonantum, a sub-tribe of the Massachusett led by a sachem named Waban, to relocate to Natick in 1651, fearing that they would be exploited by colonists. Newton was incorporated as a separate town, known as Cambridge Village, on December 15, 1681, then renamed Newtown in 1691, and finally Newton in 1766. It became a city on January 5, 1874. Newton is known as ''The Garden City''. In ''Reflections in Bullough's Pond'', Newton historian Diana Muir describes the early industries that developed in the late 18th and early 19th centuries in a series of mills b ...
