Bethesda is a census designated place in southern Montgomery County, Maryland, USA, just northwest of Washington, D.C. It takes its name from a local church, the Bethesda Meeting House (1820, rebuilt 1849), which in turn took its name from Jerusalem's Pool of Bethesda. (In Aramaic, beth hesda means "House of Mercy" and in Hebrew, "bait" "chesed" means "House of Kindness".) The National Institutes of Health main campus and the National Naval Medical Center are in Bethesda, as are a number of corporate and government headquarters. Bethesda is one of the most affluent and highly educated communities in the country, placing first in Forbes list of America's most educated small towns and first on CNNMoney.com's list of top-earning American towns. In April 2009, Forbes ranked Bethesda second on its list of "America's Most Livable Cities." In October 2009, based on education, income, health, and fitness, Total Beauty ranked Bethesda first on its list of the U.S.'s "Top 10 Hottest-Guy Cities."
