The coat of arms of Pennsylvania

Pennsylvania (/ˌpɛnsɪlˈvniə/ , lit.'Penn's forest country'), officially the Commonwealth of Pennsylvania (Pennsylvania Dutch: Pennsylvanie), is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. Pennsylvania borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio and the Ohio River to its west, Lake Erie and New York to its north, the Delaware River and New Jersey to its east, and the Canadian province of Ontario to its northwest.

Pennsylvania was founded in 1681 through a royal land grant to William Penn, the son of the state's namesake. Prior to that, between 1638 and 1655, a southeast portion of the state was part of New Sweden, a Swedish Empire colony. Established as a haven for religious and political tolerance, the 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 and historic role in the American Revolution and the ultimately successful quest for independence from the British Empire, hosting the First and Second Continental Congress, leading to the adoption of the Declaration of Independence and the formation of the Continental Army. On December 12, 1787, Pennsylvania became the second state to ratify the U.S. Constitution. The bloodiest battle of the American Civil War, at Gettysburg over three days in July 1863, proved the war's turning point, leading to the Union's preservation. Throughout the late 19th and 20th centuries, the state's manufacturing-based economy contributed to the development of much of the nation's early infrastructure, including key bridges, skyscrapers, and military hardware used in U.S.-led victories in World War I, World War II, and the Cold War.

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; close to 60% of the state is forested. While it has no ocean shoreline, it has 140 miles (225 km) of waterfront along Lake Erie and the tidal Delaware River. (Full article...)

Carson in 1943

Rachel Louise Carson (May 27, 1907 – April 14, 1964) was an American marine biologist, writer, and conservationist whose sea trilogy (1941–1955) and book Silent Spring (1962) are credited with advancing marine conservation and the global environmental movement.

Carson began her career as an aquatic biologist in the U.S. Bureau of Fisheries, and became a full-time nature writer in the 1950s. Her widely praised 1951 bestseller The Sea Around Us won her a U.S. National Book Award, recognition as a gifted writer and financial security. Its success prompted the republication of her first book, Under the Sea Wind (1941), in 1952, which was followed by The Edge of the Sea in 1955 — both were also bestsellers. This sea trilogy explores the whole of ocean life from the shores to the depths. (Full article...)

Forbes Field was a baseball park in the Oakland neighborhood of Pittsburgh, Pennsylvania, from 1909 to June 28, 1970. It was the third home of the Pittsburgh Pirates, the city's Major League Baseball (MLB) team, and the first home of the Pittsburgh Steelers, the city's National Football League (NFL) franchise. From 1909 to 1924, the stadium also served as the home football field for the University of Pittsburgh "Pitt" Panthers. The stadium sat on Forbes Avenue, named for British general John Forbes, who fought in the French and Indian War and named the city in 1758.

The US$1 million ($33.9 million today) project was launched by Pittsburgh Pirates' owner Barney Dreyfuss to replace his franchise's second home, Exposition Park. The stadium was made of concrete and steel, the first such stadium in the National League and third in Major League Baseball, in a bid to be more durable than wooden ballparks. The Pirates opened Forbes Field on June 30, 1909, against the Chicago Cubs, and played the final game against the Cubs on June 28, 1970. The field itself featured a large playing surface, with the batting cage placed in the deepest part of center field during games. Seating was altered multiple times throughout the stadium's life; at times fans were permitted to sit on the grass in the outfield during overflow crowds. The Pirates won three World Series while at Forbes Field; the Pittsburgh Panthers football team had five undefeated seasons before moving in 1924. In 1958, broadcaster Bob Prince dubbed Forbes Field "The House of Thrills" for the then-resurgent Pirates and several games that saw late-inning heroics. (Full article...)

Map of Pennsylvania Railroad up to 1945

The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company, also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia. It was named for the commonwealth in which it was established. At its peak in 1882, the Pennsylvania Railroad was the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world.

Over its existence, Pennsylvania Railroad acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated 11,640.66 miles (18,733.83 kilometers) of rail line; in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Central Railroad (NYC), which carried around three-quarters of the Pennsy's ton-miles. (Full article...)
