First refracting telescope

In 1608, Johannes Lippershey (c.1570-c.1619) demonstrated a new invention, the first optical (refracting) telescope - prototype of the modern telescopes - to the Netherlands States General.

An apprentice discovered that - by separating both a long-focus lens and a short-focus lens in front of the eye - distant objects appeared closer. Lippershey mounted lenses in tubes, applied for a patent in 1608, and also offered them for sale to the Dutch government, which appreciated their military value.
