The Gregorian refracting telescope was invented by Scottish mathematician and astronomer James Gregory in the 17th century. He designed this telescope to address some of the optical issues of the existing telescopes at that time.
Thomas Edison is credited with inventing the first practical light bulb in 1879.
Galileo Galilei is the astronomer who is credited with inventing the telescope and using it to support the heliocentric theory proposed by Copernicus. He observed the moons of Jupiter, sunspots, and phases of Venus, providing evidence for a Sun-centered solar system.
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879.
Both were developed in The Netherlands.The first true microscope was made around 1595 in Middelburg, The Netherlands, developed by Hans Lippershey or Sacharias Jansen.The first true telescope first appeared in 1608. Again, credit goes to the aforementioned Hans Lippershey and Sacharias Jansen.

a Dutch spectacle-maker from Middlburg credited with inventing, or contributing advances towards the invention of the first telescope. Jansen is sometimes credited for inventing the first truly compound microscope.
Hans Lippershey is usually credited with inventing the telescope, although it is unclear if he was actually the first to build one.
The Wright brothers.
The telescope was improved by several astronomers and inventors over time. Some key figures include Galileo Galilei, who made significant advancements in telescope design in the 17th century, and Hans Lippershey, who is often credited with inventing the first practical telescope in the early 1600s.
Alessandro Volta is credited with inventing the first battery in 1800. His invention, known as the Voltaic pile, was the first electrochemical cell capable of producing a steady electric current.
