Answer 2

When Benjamin Franklin invented his mechanical version of the instrument in 1761, he called it the armonica, based on the Italian word armonia, which means "harmony". The unrelated free-reed wind instrument aeolina, today called the " harmonica ", was not invented until 1821, sixty years later.
