Who invented bells

In the beginning those bells were used only as a means of spreading information, such as notifying workers that their work day is done. This design had a special shape that can create two notes, which enabled bell to become part of various musical performances.

Rise of the popularity of the bells in the china soon enabled it to become a status symbol. Elaborate designs of bells started appearing all across the country with royals and nobility viewing it as a symbol of power Emperor had four bells on each side of his residence, duke or prince three bells, minister two and government official one. After initial development in China, bells started spreading across Asia, often being deeply connected with the religion. Buddhism and Hinduism accepted bells as the integral parts of their religious ceremonies, with belief that temple cannot be called temple without a bell inside of it.

Japanese Shinto religion also embraced bells, especially types called Suzu and Kane. Fist popularization of bells in the western culture started in 5th century AD in Italy where Benedictine monks in the Campana region learnt how to cast iron and create bells that were shaped much differently than the modern church bells.

Young Alexander was an intellectually curious child who studied piano and began inventing things at an early age. Both of his brothers passed away from tuberculosis by the time Bell was in his early twenties.

When he was just 12, the young Alexander invented a device with rotating paddles and nail brushes that could quickly remove husks from wheat grain to help improve a farming process.

At age 16, Bell began studying the mechanics of speech. In , Bell, along with his family, moved to Canada. The following year, he settled in the United States. While in the U. In , he opened the School of Vocal Physiology and Mechanics of Speech in Boston, where deaf people were taught to speak. While teaching, Bell met Mabel Hubbard, a deaf student.

The couple married on July 11, They went on to have four children, including two sons who died as infants. In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time. While trying to perfect this technology, which was backed by a group of investors, Bell became preoccupied with finding a way to transmit human voice over wires. By , Bell, with the help of his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.

On March 7, , Bell was granted his telephone patent. Watson, come here. I want you. In , the U. In addition to the telephone, Bell worked on hundreds of projects throughout his career and received patents in various fields.

Some of his other notable inventions were:. In , Bell was awarded the French Volta Prize, and with the money, he founded a facility devoted to scientific discovery, the Volta Laboratory in Washington, D. Bell invented numerous techniques to help teach speech to the deaf and even worked with well-known author and activist Helen Keller. He also helped launch Science magazine , and from to served as president of the National Geographic Society.

As he wrote to his parents in , Bell had been aware of his competitor's efforts and felt enormous pressure to finish his own design. Gray and myself who shall complete our apparatus first," he observed, according to Charlotte Gray's Reluctant Genius: Alexander Graham Bell and the Passion for Invention. In March , Bell received the telephone patent. Competitor Western Union hired other inventors, including Gray, to develop their own phone system, which led to a legal fight between the two businesses.

Over the years, Bell vigorously defended his telephone patent in a number of other lawsuits. Bell created the photophone, which used light to transmit sound. Bell considered it to be one of his greatest inventions.

He also used his gift for inventing to solve problems. After the death of his infant son in , Bell made a metal vacuum jacket to help with breathing. This idea influenced the design of the iron lung device used to aid polio patients in the s. When an assassin shot President James Garfield in , Bell was asked to help the ailing leader.

He came up with an electromagnetic machine to detect where the bullet was lodged in Garfield's body. It failed at this task Garfield later died , but the device was a precursor to the modern metal detector.

He started out experimenting with kites in the s and even had a special building on his estate, Beinn Bhreagh, to work on these projects.

After a lot of experimentation, Bell created an innovative kite design based on tetrahedrons. The association developed flying machines, the most famous of which was the Silver Dart. On February 23, , the Silver Dart became the first plane to make a powered flight in Canada.

Bell later worked on hydrofoils with Baldwin. One of their designs, known as HD-4, set a speed record in
