Necessity is the mother of invention

I think the phrase, "Necessity is the mother of invention." means that people needed things like, telephones or automobiles or electricity in the past. They were needed so much that people were searching for ways to invent these things. For example, the automobile was built by Henry Ford (Henry Ford and his first automobile below ) and he said, "I will build a car for the great multitude." in 1903. Five years later in 1908, he did. Another invention was the telephone, invented by Alexander Graham Bell. Alexander experimented with electrical signals. He invented this so that he could communicate easier. This is what I think that phrase means.
