Hans Lippershey created and disseminated the first practical telescope.
The first refracting telescope was invented by Hans Lippershey in 1608.
In 1609, Galileo was the first person to use a telescope to observe the skies (after hearing about Hans Lippershey's newly-invented telescope).

The first major component is the primary mirror. Newton's first telescope mirror was made out metal and was roughly two inches in diameter. Virtually all modern telescopes use mirrors made out of glass, quartz, or glass/ceramic composites. Amateur astronomers frequently use Pyrex blanks especially manufactured for optical fabrication, although ordinary plate glass such as portholes have also been used for primary mirrors.
The primary mirror has a concave shape, which makes it magnify like a shaving mirror. If you have a point light source infinitely far away, the mirror will form an image of the point some distance in front of the mirror. The distance between this image and the main mirror is the focal length of the mirror. If you divide the focal length of the mirror by the diameter of the mirror, you get the focal ratio. Reflecting telescopes are often described by the diameter of their primary mirror followed by their focal ratio. For example, a common telescope might have a primary diameter of eight inches, and a focal length of 48 inches. One could describe such a telescope as an 8" f/6 reflector.

Galileo invented and used the modern telescope to discover the rings of Jupiter. Any other device before his time wasn't precise enough.

The earliest documented telescope was that of Roger Bacon in the 13th century. It is quite certain that prior to 1600 the telescope was unknown, except to individuals who failed to see its practical importance, and who confined its usage to curious practices or to demonstrations of "natural magic."

Woman36 got it right. It was NOT Galileo. Hans Lippershey, a Dutch spectacles maker, invented it in 1608; Galileo demonstrated it a year later.
