The telescope is one of humankind’s most important inventions. The simple device that made far away things look near gave observers a new perspective. When curious men pointed the spyglass toward the sky, our view of Earth and our place in the universe changed forever.
But who invented the telescope? The answer remains a mystery today. It is highly probable that as glassmaking and lens-grinding techniques improved in the late 1500s, someone held up two lenses and discovered what they could do.
