Who invented bell canada




















Bell is the first company in North America to invest in digital switching technology, a vital long-term step into the digital era. Don Black, corporate design manager, was one of the key persons involved in developing this word-symbol version of the corporate logo, making its first appearance on company vehicles in Bell was on its way to becoming much more.

An exceptional engineer and executive, Mr. Cyr grasped both the technical and corporate opportunities at Bell in the early days of cellular technology. BCE becomes the parent company of Bell Canada. Bernard was also known for her community involvement and her support for organizations that helped the under privileged.

Starting in , he served in a variety of senior management positions, before his appointment as President. Under Mr. Monty was appointed President of Bell Canada in May , bringing his deep experience and understanding of markets, telecommunications and technology to the helm of Bell and BCE.

Bell establishes a full-time environmental group to manage a comprehensive company-wide program. The environmental policy is embedded in the company's Business Code of Conduct. Kearney joined Bell in at the Treasury Department before moving on to a variety of management and technical positions in Accounting and Systems.

During the McLennan era, Bell unveiled a 3-year plan to streamline operations in order to allow a more effective response to the market and Bell customers. On December 8, , Bell Canada launched a distinctive new logo. At the center is the human profile, representing Bell employees and the focus of all their efforts, the customer.

The profile is set within two open rings, symbolizing the dynamic future of telecommunications—the ability to transmit sound, image and data instantly, wirelessly, across all frontiers.

The Bell name appears directly beneath the profile, a graphic representation of how the company supports customers in all their communications needs. As our primary colour for nearly two decades, the blue reflects and builds on tradition, but with a more vibrant tone. The warm yellow shade represents change. Launch of Bell. The launch of Sympatico Internet and our website Bell.

Osborne earned a degree from Cambridge University in before becoming an accountant at a Toronto-based firm 4 years later. He is a graduate of Dalhousie University and the Technical School of Nova Scotia, where he obtained a Bachelor of Science degree in electrical engineering. Bell is the first in North America to offer mobile Internet services. Combining Bell Canada and Bell Mobility retail operations, the stores are the first in Canada to provide complete and integrated communications solutions including wireline, wireless, and direct-to-home satellite broadcasting services.

Building on more than a century of corporate giving and active volunteerism of team members and retirees, Bell introduces a new Employee Giving Program to better encourage and recognize community involvement across our business units. He joined Bell in and held numerous executive positions during his year career with the company. Bell Mobility launches the first 3G network in Toronto with 1X. He knew that a sound's pitch relies on its frequency-how quickly it vibrates-and that everything has its own natural frequency.

By singing into a piano he discovered that varying the pitch of his voice made different piano strings vibrate in return. His observations led to the idea of sending many different messages, with tuning forks tuned to different frequencies, along a single wire, a system he called the harmonic telegraph.

The message was received at the other end of the wire with identical tuning forks. To explore the reception of sound vibrations, Bell constructed an apparatus consisting of a sheet of blackened glass, a mouthpiece and a long wooden lever with a bristle on its edge, attached to a stretched membrane. A sound sent down the mouthpiece made the bristle move up and down on the membrane, tracing the shape of the vibration. When the membrane proved insufficiently sensitive, his friend, ear specialist Dr.

Clarence Blake, gave Bell a cadaver ear to study. Bell applied his understanding of the human ear to the telephone. Bell returned to Brantford in , exhausted. Mulling over all of his observations, Bell realized that with electricity, "it would be possible to transmit sounds of any sort" by controlling the intensity of the current.

Based on his new insight, he sketched a primitive telephone. By October , Bell's research had been so successful that he was able to inform his future father-in-law, Boston attorney Gardiner Greene Hubbard, about the possibility of a multiple telegraph.

Hubbard resented the Western Union Telegraph Company's communications monopoly and gave Bell the financial backing he needed, along with leather merchant Thomas Sanders, the father of one of Bell's students.

Bell worked on the multiple telegraph with a young electrician, Thomas Watson, but at the same time, he and Watson were exploring an idea that had occurred to him that summer for a device that would transmit speech electrically.

Bell also met with Joseph Henry, director of the Smithsonian Institution, in March to discuss ideas for the telephone. When Bell began to experiment with electrical signals, the telegraph had existed for more than 30 years. Although it was a successful system, the telegraph was limited to receiving and sending one message at a time, using Morse code.

By the early s, a number of inventors including Thomas Edison and Elisha Gray were working on a telegraph that that could transmit simultaneous messages. Even before coming to Canada, Bell had been intrigued by the idea of using a well-known musical phenomenon to transmit multiple telegraph messages simultaneously.

He knew that everything has a natural frequency how quickly something vibrates and that a sound's pitch relies on its frequency. By singing into a piano he discovered that varying the pitch of his voice made different piano strings vibrate in return. His observations led to the idea of sending many different messages along a single wire, with identical tuning forks tuned to different frequencies at either end to send and receive, a system he called the "harmonic telegraph.

By October , Bell's research had been so successful that he informed his future father-in-law, Gardiner Greene Hubbard, about the possibility of a multiple telegraph. Hubbard resented the Western Union Telegraph Company's communications monopoly and gave Bell the financial backing he needed. Hubbard was joined by leather merchant Thomas Sanders, who was also the father of one of Bell's deaf students in Boston. Bell worked on the multiple telegraph with a young electrician, Thomas Watson.

At the same time, he and Watson were exploring the possibility of a device that would transmit speech electrically. According to Bell, inspiration struck on 26 July during a summer visit to Brantford. While watching the currents in the Grand River , Bell reflected on sound waves moving through the air and realized that with electricity, "it would be possible to transmit sounds of any sort" by controlling the intensity of the current.

Based on his new insight, he sketched a primitive telephone. The first major breakthrough occurred on 2 June Bell and Watson were preparing an experiment with the multiple telegraph by tuning reeds on three sets of transmitters and receivers in different rooms.

One of Watson's reeds, affixed too tightly, was stuck to its electromagnet. With the transmitters off, Watson plucked the reed to free it, and Bell heard a twang in his receiver.

They had inadvertently reproduced sound and proved that tones could vary the strength of an electric current in a wire. The next step was to build a working transmitter with a membrane that could vary electronic currents and a receiver that could reproduce the variations in audible frequencies. Within days Watson had built a primitive telephone. Bell continued research on the telephone, and on 14 February Hubbard submitted an application to the US Patent Office on his behalf for an undulatory current, variable resistance liquid transmitter.

On 7 March, Bell received Patent No. He and Watson continued their work, and on 10 March , Bell spoke into the first telephone, uttering the now-famous instruction to his assistant: "Mr. Watson — come here — I want to see you. Bell's work culminated in not only the birth of the telephone, but the death of the multiple telegraph. The communications potential of being able to "talk with electricity" overcame anything that could be gained by simply increasing the capacity of a dot-and-dash system.

The following day, Bell gave his father, Melville , most of his Canadian rights to the telephone. On 11 July, he married Mabel Gardiner Hubbard — and embarked on a yearlong honeymoon in Europe.

Over the next several years, the Bell company fought and won hundreds of telephone patent lawsuits in the courts, making Bell rich by age By that point, however, he had largely withdrawn from the business and turned to other interests. Bell might easily have been content with the financial success of his invention.

His many laboratory notebooks reveal the depth of the intellectual curiosity that drove him to learn and create. In , Bell received the Volta Prize from the French government, in recognition of his achievements in electrical science particularly the invention of the telephone.

Bell, and Charles Sumner Tainter. Seeking a way out, Alexander volunteered to care for his grandfather when he fell ill in The elder Bell encouraged young Alexander and instilled an appreciation for learning and intellectual pursuits. At first, Alexander resisted, for he was establishing himself in London. He eventually relented after both his brothers died of tuberculosis. In , the family settled in Brantford, Ontario, Canada. There, Alexander set up a workshop to continue his study of the human voice.

On July 11, , Bell married Mable Hubbard, a former student and the daughter of Gardiner Hubbard, one of his early financial backers. Mable had been deaf since her early childhood years. Bell is credited with inventing the telephone; in all, he personally held 18 patents along with 12 he shared with collaborators.

On March 10, , after years of work, Bell perfected his most well-known invention, the telephone, and made his first telephone call. Before then, Bell in started working on a device known as the multiple or harmonic telegraph a telegraph transmission of several messages set to different frequencies upon moving to Boston.

He found financial backing through local investors Thomas Sanders and Gardiner Hubbard. Between and , Bell spent long days and nights trying to perfect the harmonic telegraph.

But during his experiments, he became interested in another idea, transmitting the human voice over wires. Through and , Bell and Watson labored on both the harmonic telegraph and a voice transmitting device.

For now the concept was protected, but the device still had to be developed.
