This may create the appearance of a ring -- hence the name, ringworm. Worldwide, the fungus Microsporum audouinii is a very common cause of ringworm, but increasingly Trichophyton tonsurans can also cause tinea capitis, especially in the US and Latin American countries.
The telephone was invented on the 10th March 1876. The telephone was invented by Alexander Graham Bell, a Scottish inventor, scientist and engineer. Alexander Graham Bell actually considered his invention of the telephone to be an intrusion of his scientific work and refused to have one installed in his study.
Alexander Graham Bell is often credited as the inventor of the telephone since he was awarded the first successful patent. However, there were many other inventors such as Elisha Gray and Antonio Meucci who also developed a talking telegraph. Attributing the true inventor or inventors to a specific invention can be tricky business.
