"My God, it speaks" uttered the Emperor of Brazil and the receiver of the Telephone slipped from his hand and banged aground. At the other end, Alexander Graham Bell was still on line. This incident goes back to 1876 when at an exhibition in Philadelphia (USA), Alexander Graham Bell was giving a demonstration of his new invention. This strange instrument known as Telephone was to revolutionize life in the years to come. Bell was born at Edenborough, Scotland. He was a teacher and was dedicated to the noble cause of teaching the deaf and the dumb. Due to a severe illness, Bell was sent to Canada in 1870, where too he got engaged in helping the dumb-deaf to hear and speak. Thereafter, he shifted to the USA but continued with his work by opening a school for deaf and dumb. Bell was fond of scientific inventions and was ever engaged in making some machines in his spare time. While at Boston, he tried to communicate through metal wire. His companion in this work was Watson. One day while experimenting with his instrument, Bell spoke to Watson standing at a distance. Watson was taken by a pleasant surprise as he had heard Bell clearly through his instrument. The instrument was a success and Bell patented it.
Graham Bell had some sterling qualities of head and heart. Apart from being an artist, he was a kind human being, ready to help the needy. He established an institution for the deaf and dumb children. He died in 1922 in Canada. The entire northern America paid him a tribute by hanging up their telephones for a while during his funeral.
Alexander Graham Bell traveled to Canada in the year 1870 primarily due to personal health reasons.
He was himself suffering from ill health, reportedly tuberculosis, which necessitated the trip for recovery and treatment.
While Bell was deeply involved in work related to sound and communication, particularly concerning the deaf, his personal medical needs were the driving force behind this specific journey to Canada.
The family connection was also strong, as his parents had recently relocated to Brantford, Ontario.

In the 1960s, Jane Goodhall observed chimpanzees removing termites from hides with strapped twigs. Initially, researchers were unable to determine whether the animals viewed a group of tasks as a single problem requiring a general tool set or used individual tools to solve specific tasks. The question was finally resolved when chimps were observed selecting tools to carry with them in anticipation of particular difficulties. Research, therefore, concluded that not only are chimpanzees capable of using tools in a sophisticated way, but they ________
