Who proposed that Earth was only 6,000 years old?

In the seventeenth century Archbishop James Ussher (1581-1656) of the Irish Protestant Church calculated from the Old Testament genealogies that Earth was created on Sunday, October 26, 4004 B.C.E. He was also able to calculate exact dates for when Adam and Eve were forced from Paradise (Monday, November 10, 4004 B.C.E.) and when Noah's Ark touched down on Mt. Ararat (Wednesday, May 5, 1491 B.C.E.).
