Microscopes help us to see tiny objects that can't be seen with the naked eye. The earliest microscope invented was in 1590 in Middelburg in the Netherlands and the inventer was Hans Lippershy and Zacharias Janssen. In 1625 a compound microscope was invented by Giovanni Faber, he coined the name Gailileo Galilei's compound microscope. (Galileo called the compound microscope "occhiolino" or "little eye".)
