The first telescope maker?

• A. Galileo Galilei
• B. Hans Lippershey
• C. Isaac Newton
• D. Christiaan Huygens

Answer: (B)

The earliest practical telescope was built by Hans Lippershey, a Dutch spectacle maker, who in 1608 assembled a device using lenses to magnify distant objects and sought a patent for it. This makes him the first known creator of a working telescope. Galileo Galilei soon learned about the invention and made his own improved version, using it to observe the Moon’s craters and Jupiter’s moons, which sparked major astronomical discoveries, but he did not invent the instrument. Isaac Newton and Christiaan Huygens contributed later to telescope design and optics, but the first inventor is Lippershey.
