Chester William Nimitz, Sr. (/ËnÉªmÉªts/; February 24, 1885 â February 20, 1966) was a fleet admiral of the United States Navy.
Origin: Chester was first known as the chestnut country, and may have been the first of the settlement grants by the Governor of Massachusetts in 1722 for expansion of New Hampshire's seacoast settlements. Many new settlers were from Hampton, Newbury, Kingston, and Portsmouth, which were considered overcrowded.
