The coat of arms of Pennsylvania

Pennsylvania, officially the Commonwealth of Pennsylvania, is a state located in the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. The state borders Delaware to its southeast, Maryland to its south, forming the Mason–Dixon line, West Virginia to its southwest, Ohio to its west, the Canadian province of Ontario to its northwest via Lake Erie, New York to its north, and the Delaware River and New Jersey to its east. Pennsylvania is the fifth-most populous U.S. state, home to over 13 million residents as of the 2020 United States census, and the ninth-highest state by population density. It is the 33rd-largest state by land area. The largest metropolitan statistical area is the Philadelphia metropolitan area/Delaware Valley, centered on Philadelphia, the state's most populous city and sixth-most populous U.S. city, and an expanding biopharmaceutical, commercial, educational, entrepreneurial/venture capital, industrial, and transportational hub. Pennsylvania's second-largest metropolitan area, Greater Pittsburgh, is centered in and around Pittsburgh, also a biopharmaceutical hub and the Commonwealth's second-largest city. Geographically situated between the two larger metros lies Harrisburg, the capital city of Pennsylvania.

Pennsylvania's geography is highly diverse. The Appalachian Mountains run through the center of the state, the Allegheny and Pocono mountains span much of Northeastern Pennsylvania, and approximately 59% of the state is forested. Although Pennsylvania technically has no oceanic shoreline, it has 140 miles (225 km) of waterfront along Lake Erie and along the tidal Delaware River, the latter of which reaches the Delaware Bay, a marginal bay of the Atlantic Ocean.

Pennsylvania was founded in 1681 through a royal land grant to William Penn, the son of the commonwealth's namesake. Before that, between 1638 and 1655, a southeast portion of the state was part of New Sweden, a Swedish colony. Established as a haven for religious and political tolerance, the British colonial-era Province of Pennsylvania was known for its relatively peaceful relations with native tribes, innovative government system, and religious pluralism. Pennsylvania played a vital historical role in the American Revolution and the ultimately successful quest for independence from the British Empire, hosting the First and Second Continental Congress in Philadelphia, the latter of which formed the Continental Army commanded by George Washington in 1775, during the American Revolutionary War, unanimously adopted the Declaration of Independence the following year. On December 12, 1787, Pennsylvania was the second state to ratify the U.S. Constitution after Delaware. (Full article...)

Goldstein in 2008

Adam Michael Goldstein (March 30, 1973 – August 28, 2009), known professionally as DJ AM, was an American DJ. Born in Philadelphia, Goldstein became interested in deejaying as a child after watching Herbie Hancock perform his 1983 single "Rockit". Goldstein developed a drug addiction as a teenager and was sent to the controversial rehabilitation center Straight, Incorporated. After he left the center, his drug problems became worse; he was addicted to crack cocaine for several years in his early twenties. After he attempted suicide in 1997, Goldstein became sober and later sponsored other addicts through Alcoholics Anonymous.

Goldstein began deejaying in clubs in Los Angeles and joined the band Crazy Town in 1999. He left the group in 2001 and focused on a career as a solo DJ. After he began dating Nicole Richie in 2003, his career skyrocketed. In 2006, he accepted a $1 million contract to perform weekly at Caesars Palace on the Las Vegas strip and was also charging upwards of $10,000 for private events. In 2008, Goldstein and Travis Barker formed the duo TRV$DJAM. Barker and Goldstein were the only two survivors of the 2008 South Carolina Learjet 60 crash, which killed the other four people on board. (Full article...)

Duncan & Miller Glass Company was a well-known glass manufacturing company in Washington, Pennsylvania. Items that were produced by the company are known as "Duncan glass" or "Duncan Miller glass." The company was founded in 1865 by George Duncan with his two sons and son-in-law in the South Side neighborhood of Pittsburgh, Pennsylvania. By 1890, the company joined other glass companies to form the United States Glass Company, a powerful glass trust. In 1892, the factory was destroyed in a fire, and the company was relieved of its trust relationship with the US Glass Company. After the fire, the second generation of the Duncan family moved operations to Washington, Pennsylvania. In 1900, John Ernest Miller, the company's long-time designer, became a full shareholder along with members of the Duncan family. By 1955, economic pressures from machine-produced glass forced the company to sell off its assets to the US Glass Company, who continued to produce Duncan-style glass until 1980. (Full article...)

Cosby in 2011

William Henry Cosby Jr. (/ˈkɒzbi/ KOZ-bee; born July 12, 1937) is an American former comedian, actor, and media personality. Often deemed a trailblazer for African Americans in the entertainment industry, Cosby was well known in the United States for his stand-up comedy routines and television career before achieving global recognition for his portrayal of Cliff Huxtable in the sitcom The Cosby Show (1984–1992). He was also prolific in advertising for decades and was the recipient of numerous awards and honorary degrees throughout his career, many of which were revoked after dozens of allegations of sexual assault were made against him, starting in 2014 and culminating in a 2018 conviction for aggravated indecent assault.

Cosby began his career as a stand-up comic at the Hungry I nightclub in San Francisco in 1961, and primarily performed observational comedy in a conversational style. He released LP records of numerous standup specials starting with Bill Cosby Is a Very Funny Fellow...Right! (1963) and starred in the comedy film Bill Cosby: Himself (1983). Cosby still holds the record for winning the most Grammy Awards for Best Comedy Album, with seven wins. His acting career began with a starring role in the NBC secret-agent show I Spy (1965–1968), which broke new ground for African Americans when he made history by winning three Primetime Emmy Awards for Best Actor in a Drama Series, becoming the first black actor to do so.
