Sellers Hall
Sellers Hall, completed in 1684, is one of the oldest buildings in Pennsylvania and is the ancestral home of the Sellers Family of Scientists, Sellers family of scientists and engineers. Samuel Sellers (1655-1732) arrived in Philadelphia in 1682, the first year of Penn's colony. A young man, he was eager to marry, which explains the very early date of the house. He married Anna Gibbons (1655-1743) on August 13, 1684, and moved into Sellers Hall. The Sellers' declaration of intention to marry is the first entry in the minutes of Darby meeting. Samuel Sellers brought with him from Derbyshire in England the technology for making and weaving wire. This technology, and his mills on Cobbs Creek in Upper Darby, became the basis for a series of inventions and mechanical innovations that would lead to the creation of the early Pennsylvania textile industry at Cardington, the North American paper-making industry, and the fire-hose, fire-engine, and locomotive-making industries in Pennsylva ...

Sellers Family Of Scientists
The Sellers family of Philadelphia and Delaware County, Pennsylvania, are a family of scientists and engineers. More members of the Sellers family and the closely related Peale family have belonged to the American Philosophical Society than any other family in the history of the United States, and the same is true of the Academy of Natural Sciences, the Franklin Institute, and the Pennsylvania Academy of the Fine Arts. Notable members Among the best-known members of the Sellers family are: John Sellers (1728–1804) observer of the transit of Venus; William Sellers (1824–1905) designer of the standard screw thread; George Eschol Sellers (1808–1899) designer of the Panama Railway, Coleman Sellers (1827–1907) inventor of the cinema and developer of hydroelectric technology; Horace Wells Sellers (1857–1933) restorer of Independence Hall; and Peter Hoadley Sellers (1930–2014) deviser of the mathematical algorithms used to decode DNA.

Upper Darby
Upper Darby Township, often shortened to Upper Darby, is a home rule township in Delaware County, Pennsylvania. The township borders Philadelphia, the nation's sixth most populous city as of 2020 with 1.6 million residents. As of the 2020 census, the township had a total population of 85,681, making it the sixth most populated city or borough in Pennsylvania, after Philadelphia, Pittsburgh, Allentown, Reading, and Erie. Upper Darby is 65% residential, 25% commercial, and 8% other. Upper Darby is home to the Tower Theater, a historic music venue on 69th Street built in the 1920s, and is also home to several Underground Railroad sites. Upper Darby's population is diverse, representing over 100 ethnic cultures. The township hosts a range of housing types including densely populated rowhouse sections similar to houses in neighboring West Philadelphia, tree-lined neighborhoods of turn-of-the-century single-family houses and mid-century developments.

John Sellers (scientist)
John Sellers (1728 – 1804), was an American scientist, engineer, and legislator, who was born at Sellers Hall in Upper Darby, Pennsylvania, on November 19, 1728. Sellers was one of the original members of the American Philosophical Society and with David Rittenhouse and others was one of the committee of that organization that observed the Transit of Venus in 1769 and reported their observations for the benefit of science. He was a skilled surveyor and engineer and played a part on numerous public works, including the construction of the Strasburg road in 1772, the Schuylkill-Susquehanna canal study of 1783, and the boundary commission for the newly created Delaware County in 1789. Public spirited and capable, Sellers played an important role in political affairs throughout his life, first in the colonial Assembly from 1767, and then in efforts on behalf of American rights and eventually Independence. He was appointed one of the Boston Port Bill Committee and was a deputy in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Philosophical Society
The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and community outreach. Considered the first learned society in the United States, it has about 1,000 elected members, and by April 2020 had had only 5,710 members since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanities and the sciences. Philosophical Hall, now a museum, is just east of Independence Hall in Independence National Historical Park; it was designated a National Historic Landmark in 1965. History The Philosophical Society, as it was originally called, was founded in 1743 by Benjamin Franklin, James Alexander (lawyer), James Alexander, Francis Hopkinson, John Bartram, Philip Syn ...

Pennsylvania Constitution
The Constitution of Pennsylvania is the supreme law within the Commonwealth of Pennsylvania. All acts of the General Assembly, the governor, and each governmental agency are subordinate to it. Since 1776, Pennsylvania's Constitution has undergone five versions. The current Constitution entered into force in 1968, and has been amended numerous times. The Constitution may only be amended if a proposed modification receives a majority vote of two consecutive sessions of the General Assembly and then is approved by the electorate. Emergency amendments are permitted by a vote of two-thirds of the General Assembly and an affirmative vote by the electorate within one month. In such emergency situations, commonwealth election officials are required to publish notice of the referendum on a proposed amendment in a minimum of two newspapers in every county. In an event that more than one emergency amendment is proposed, each additional amendment is to be voted on separately. The Constitut ...

David Rittenhouse
David Rittenhouse (April 8, 1732 – June 26, 1796) was an American astronomer, inventor, clockmaker, mathematician, surveyor, scientific instrument craftsman, and public official. Rittenhouse was a member of the American Philosophical Society and the first director of the United States Mint. Biography David Rittenhouse was born on April 8, 1732, in Roxborough Township, Philadelphia County, near a small village within Philadelphia called Rittenhousetown. This village is located near Germantown, along the stream Paper Mill Run, which is a tiny tributary of the Wissahickon Creek. When his uncle, William Rittenhouse, died, David inherited his uncle's carpentry tools and instructional books. At a young age, David showed a high level of intelligence by creating a working scale model of his great-grandfather William Rittenhouse's paper mill. He built other scale models in his youth, like a working waterwheel. David never attended elementary school—he was self-taught from his f ...

Transit Of Venus
frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black dot moving across the face of the Sun. The duration of such transits is usually several hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than three times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth. Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that generally repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Railroad
The Underground Railroad was a network of clandestine routes and safe houses established in the United States during the early- to mid-19th century. It was used by enslaved African Americans primarily to escape into free states and Canada. The network was assisted by abolitionists and others sympathetic to the cause of the escapees. The enslaved persons who risked escape and those who aided them are also collectively referred to as the "Underground Railroad". Various other routes led to Mexico, where slavery had been abolished, and to islands in the Caribbean that were not part of the slave trade. An earlier escape route running south toward Florida, then a Spanish possession (except 1763–1783), existed from the late 17th century until approximately 1790. However, the network now generally known as the Underground Railroad began in the late 18th century. It ran north and grew steadily until the Emancipation Proclamation was signed by President Abraham Lincoln.Vox, Lisa"How D ...
