Kenneth Edgeworth, Irish astronomer (d. 1972)
Kenneth Essex Edgeworth (26 February 1880 – 10 October 1972) 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.
