Who invented telescope

Many people believe that Galileo Galilei was the first astronomer to invent and build the telescope; however, the first telescope was made by Hans Lippershey in the early 1600s. Lipperhey was a German-Dutch glass maker, and he managed to reduce the amount of light in his telescope while focusing it. His model inspired other scientists to work on perfecting the telescope. It is easy to point to Hans Lipperhey as the inventor of the telescope, but the history of its invention is chaotic and confusing. Historians and scientists today still argue about who invented the telescope. Let’s take a look at the telescope and its impact on scientific history. What is the History of the Telescope? The telescope traces back to early makers of eyeglasses and lenses. In the 1400s, glasses were used widely across Europe. These lenses were not powerful, not polished, and not clear. Due to their imperfections, they were not useful for astronomic observation. By the end of the 1500s and early 1600s, lens makers improved their abilities to cut and polish glasses. It was at this time that Hans Lippershey, who made spectacles in the Netherlands, began experimenting with lenses. Lipperhey put a mask on his telescope that only allowed a small amount of light to enter his telescope. When he reduced the amount of light and focused it, the images became clear but remained dim. No other telescope makers had done this, and Lipperhey’s telescope was the beginning of the telescope’s evolution. In Septemb...

The history of the telescope dates back to the early 1600s. Galileo Galilei is commonly credited for inventing the telescope, but this is not accurate. Galileo was the first to use a telescope for the purpose of astronomy in 1609 (400 years ago in 2009, which is currently being celebrated as the Lipperhey combined curved lenses to magnify objects by up to 3 times, and eventually crafted sets of binocular telescopes for the Government of the Netherlands. There exists some confusion as to who actually came up with the idea first. Lipperhey’s patent application is the earliest on record, so this is usually used to settle the debate, although another spectacle-maker, Jacob Metius of Alkmaar, a city in the northern part of the Netherlands, filed for a patent for the same device a few weeks after Lipperhey. Another spectacle-maker, Sacharias Janssen, also claimed to have invented the telescope decades after the initial claims by Lipperhey and Metius.

Revised 18 September 2022 Telescopes are instruments which use multiple lenses to produce magnified images of distant objects. It is unclear who invented the first telescope: lenses had been widely used in Europe to correct poor eyesight since the fourteenth century and I expect that, over time, the telescope was actually invented many times by different individuals, who discovered that combining different lenses could produce a magnified image. In 1608 a spectacle maker called Hans Lippershey applied to the Dutch government for a patent for a device for seeing at a distance. His application was refused and, in the resulting publicity, the Italian astronomer Galileo Galilei (1564-1642) became aware of the device. Galileo refined the early telescopes to produce instruments with better magnification and in 1609 he took the first recorded astronomical observations with a telescope. Indeed, the first use of the word telescope, which is constructed from the Greek words ‘tele’ meaning ‘far’ and ‘skopos’ meaning ‘seeing’, is associated with Galileo’s instrument.

Telescopes of this design are called Galilean telescopes and to understand how they work it is necessary to understand a little about lenses. There are two main types of lens: • a converging lens, shown in the top...

But what made Ronan’s telescope different was that it was built to a design pre-dating Lippershey’s by decades. Ronan claimed that an Elizabethan surveyor named Leonard Digges had found a combination of a glass lens and curved mirror that also made distant objects appear closer. Descriptions of the device began to circulate around 1570, and its potential military use prompted Lord Burghley, chief adviser to Elizabeth I, to commission a report. After discovering this manuscript in the British Library, Ronan built the device, and suggested that it had a claim to being the first telescope. He also suggested Digges’s son, Thomas, had used it to observe the sky years before Galileo. Ronan’s claim has failed to convince historians, however. They argue that Elizabethan technology was not capable of making the optical components to the required quality, and that the telescope is too awkward to use in any case. So the consensus remains that Lippershey is the originator of the first working telescope.
