A compound microscope was invented in the Netherlands in the early 17th century

To be honest, this all sounds incredibly boring until you dig a little deeper into how the world of microscopic organisms,and this theory came to be.It all started in the early 1600s in the Netherlands,where a spectacle maker named Zacharias Janssen is said to have come up with the first compound microscope,along with the first telescope.Both claims are often disputed,as apparently he wasn't the only bored guy with a ton of glass lenses to play with at the time.Despite this,the microscope soon became a hot item that every naturalist or scientist at the time wanted to play with,making it much like the iPad of its day.
