Alexander Graham Bell 1847-1922
NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS VOLUME XXIII FIRST MEMOIR BIOGRAPHICAL MEMOIR OF ALEXANDER GRAHAM BELL 1847-1922 BY HAROLD S. OSBORNE PRESENTED TO THE ACADEMY AT THE ANNUAL MEETING, 1943 It was the intention that this Biographical Memoir would be written jointly by the present author and the late Dr. Bancroft Gherardi. The scope of the memoir and plan of work were laid out in cooperation with him, but Dr. Gherardi's untimely death prevented the proposed collaboration in writing the text. The author expresses his appreciation also of the help of members of the Bell family, particularly Dr. Gilbert Grosvenor, and of Mr. R. T. Barrett and Mr. A. M. Dowling of the American Telephone & Telegraph Company staff. The courtesy of these gentlemen has included, in addition to other help, making available to the author historic documents relating to the life of Alexander Graham Bell in the files of the National Geographic Society and in the Historical Museum of the American Telephone and Telegraph Company. ALEXANDER GRAHAM BELL 1847-1922 BY HAROLD S. OSBORNE Alexander Graham Bell—teacher, scientist, inventor, gentle- man—was one whose life was devoted to the benefit of mankind with unusual success. Known throughout the world as the inventor of the telephone, he made also other inventions and scientific discoveries of first importance, greatly advanced the methods and practices for teaching the deaf and came to be admired and loved throughout the world for his accuracy of thought and expression, his rigid code of honor, punctilious courtesy, and unfailing generosity in helping others. -

The Early Years of the Telephone
©2012 JSR The early years of the telephone The early years of the telephone John S. Reid Before Bell Ask who invented the telephone and most people who have an answer will reply Alexander Graham Bell, and probably clock it up as yet another invention by a Scotsman that was commercialised beyond our borders. Like many one line summaries, this is partly true but it credits to one person much more than he really deserves. Bell didn’t invent the word, he didn’t invent the concept, what ever the patent courts decreed, and actually didn’t invent most of the technology needed to turn the telephone into a business or household reality. He did, though, submit a crucial patent at just the right time in 1876, find backers to develop his concept, promoted his invention vigorously and pursued others through the courts to establish close to a monopoly business that made him and a good many others very well off. So, what is the fuller story of the early years of the telephone? In the 1820s, Charles Wheatstone who would later make a big name for himself as an inventor of telegraphy equipment invented a device he called a ‘telephone’ for transmitting music from one room to the next. It was not electrical but relied on conducting sound through a rod. In the same decade he also invented a device he called a ‘microphone’, for listening to faint sounds, but again it was not electrical. In succeeding decades quite a number of different devices by various inventors were given the name ‘telephone’. -

A History of Audio Effects

Sandler 1 1 Centre for Digital Music, Queen Mary University of London, London E1 4NS, UK; [email protected] (A.M.); [email protected] (M.B.S.) 2 Interdisciplinary Centre for Computer Music Research, University of Plymouth, Plymouth PL4 8AA, UK; [email protected] * Correspondence: [email protected] Received: 16 December 2019; Accepted: 13 January 2020; Published: 22 January 2020 Abstract: Audio effects are an essential tool that the field of music production relies upon. The ability to intentionally manipulate and modify a piece of sound has opened up considerable opportunities for music making. The evolution of technology has often driven new audio tools and effects, from early architectural acoustics through electromechanical and electronic devices to the digitisation of music production studios. Throughout time, music has constantly borrowed ideas and technological advancements from all other fields and contributed back to the innovative technology. This is defined as transsectorial innovation and fundamentally underpins the technological developments of audio effects. The development and evolution of audio effect technology is discussed, highlighting major technical breakthroughs and the impact of available audio effects. Keywords: audio effects; history; transsectorial innovation; technology; audio processing; music production 1. Introduction In this article, we describe the history of audio effects with regards to musical composition (music performance and production). We define audio effects as the controlled transformation of a sound typically based on some control parameters. As such, the term sound transformation can be considered synonymous with audio effect. -

Telephone – Inventions That Revolutionized the World
Telephone – Inventions that Revolutionized the World December 14, 2018 First Publication Date: 27th November 2010 The most common devices used for transmitting the voice signal over a greater distance are pipes and other physical mechanical media. All of us as a child must have used this form for communication. Another device used for centuries for voice communication is lover’s phone or tin can telephone. The classic example is the children’s toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with string. But the invention which changed the entire scenario of the communication is the telephone. It revolutionized the entire communication system. People could hear the voice of their loved ones staying miles away. Telephone comes from the Greek word tele, meaning from afar, and phone, meaning voice or voiced sound. Generally, a telephone is any device which conveys sound over a distance During the second half of the 19th century many well-known inventors were trying to develop an acoustic telegraphy for economic telegraph messages which included Charles Bourseul, Thomas Edison, Antonio Meucci, Johann Philipp Reis, Elisha Gray, and Alexander Graham Bell. The ‘speaking telegraph’ or in simple terms ‘telephone’ emerged from the creation and gradual improvement of telegraph. The invention of telephone has been one of the most disputed facts of all time. Credit for the invention of the electric telephone is never an ending dispute and new controversies over the issue keeps arising from time-to-time. The Elisha Gray and Alexander Bell controversy raises the question of whether Bell and Gray invented the telephone independently and, if that’s not true, then whether Bell stole the invention from Gray. -
