Kenneth Edgeworth

Kenneth Essex Edgeworth was an Irish army officer, engineer, economist and independent theoretical astronomer. He was born in Street, County Westmeath. Edgeworth is best known for proposing the existence of a disc of bodies beyond the orbit of Neptune in the 1930s. Observations later confirmed the existence of the Edgeworth-Kuiper belt in 1992. Those distant solar system bodies, including Pluto, Eris and Makemake, are now grouped into the Edgeworth-Kuiper belt, or Kuiper belt.
