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).

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.
