Actually that isn’t completely true. The Kuiper Belt was discovered in 1992 by David Jewitt and Jane Luu when they found the first Kuiper Belt Object (KBO). Jan Oort discovered the Oort Cloud which is much farther out (50000 AU from the sun) than the Kuiper Belt (30-50 AU from the sun). The Kuiper Belt is named after astronomer Gerard Kuiper for his theories on an area in the solar system past Pluto where short-period comets derived from. Then theories of long-period comets arose…but I believe that has been proven differently as they come from Scattered Disk area of the Solar System. But to your question, Kuiper Belt discovered in 1992 technically, but theorized in the mid 1990s.
