Thomas Corwin Mendenhall
Thomas Corwin Mendenhall (October 4, 1841 – March 23, 1924) was an American autodidact physicist and meteorologist. He was the first professor hired at Ohio State University in 1873 and the superintendent of the U.S. Coast and Geodetic Survey (now known as NOAA) from 1889 to 1894. Alongside his work, he was also an advocate for the adoption of the metric system by the United States and is the father of author profiling. Biography Mendenhall was born in Hanoverton, Ohio, to Stephen Mendenhall, a farmer and carriage-maker, and Mary Thomas. In 1852 the family moved to Marlboro, a Quaker community outside of Akron, Ohio. His parents were strong abolitionists and frequently opened their home to escaped slaves heading north along the Underground Railroad. Mendenhall became principal of the local primary school in 1858. He formalized his teaching qualifications at National Normal University in 1861 with an '' Instructor Normalis'' degree.Carey (1999) While living in Colu ...

Hanoverton, Ohio
Hanoverton is a village in western Columbiana County, Ohio, United States. The population was 354 at the 2020 census. It is part of the Salem micropolitan area, miles east of Canton and southwest of Youngstown. History Hanoverton was laid out in 1813 by Quaker abolitionist James Craig, and incorporated as a village in 1836. Hanoverton experienced growth in the 1830s by the building of the Sandy and Beaver Canal through the town, reaching a peak population in the late decade of around 2,000 inhabitants. Growth slowed into the 1840s, and by the 1852 completion of the Cleveland and Pittsburgh Railroad the canal was no longer profitable and the town declined. Hanoverton played a part in the Underground Railroad. An underground passage connected George Sloan's "Brick Row" with his brother-in-law Dr. James Robertson's home across the street, where runaway slaves were taken to a secret room. The Spread Eagle Tavern also was connected to a secret tunnel. In 1977 a 23-acre area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autodidact
Autodidacticism (also autodidactism) or self-education (also self-learning and self-teaching) is education without the guidance of masters (such as teachers and professors) or institutions (such as schools). Generally, autodidacts are individuals who choose the subject they will study, their studying material, and the studying rhythm and time. Autodidacts may or may not have formal education, and their study may be either a complement or an alternative to formal education. Many notable contributions have been made by autodidacts. Etymology The term has its roots in the Ancient Greek words (, ) and (, ). The related term '' didacticism'' defines an artistic philosophy of education. Terminology Various terms are used to describe self-education. One such is heutagogy, coined in 2000 by Stewart Hase and Chris Kenyon of Southern Cross University in Australia; others are ''self-directed learning'' and ''self-determined learning''. In the heutagogy paradigm, a learner should ... [...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"Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abolitionist
Abolitionism, or the abolitionist movement, is the movement to end slavery. In Western Europe and the Americas, abolitionism was a historic movement that sought to end the Atlantic slave trade and liberate the enslaved people. The British abolitionist movement started in the late 18th century when English and American Quakers began to question the morality of slavery. James Oglethorpe was among the first to articulate the Enlightenment case against slavery, banning it in the Province of Georgia on humanitarian grounds, and arguing against it in Parliament, and eventually encouraging his friends Granville Sharp and Hannah More to vigorously pursue the cause. Soon after Oglethorpe's death in 1785, Sharp and More united with William Wilberforce and others in forming the Clapham Sect. The Somersett case in 1772, in which a fugitive slave was freed with the judgement that slavery did not exist under English common law, helped launch the British movement to abolish slavery. ...

Quaker
Quakers are people who belong to a historically Protestant Christian set of denominations known formally as the Religious Society of Friends. Members of these movements ("theFriends") are generally united by a belief in each human's ability to experience the light within or see "that of God in every one". Some profess a priesthood of all believers inspired by the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity. There are also Nontheist Quakers, whose spiritual practice does not rely on the existence of God. To differing extents, the Friends avoid creeds and hierarchical structures. In 2017, there were an estimated 377,557 adult Quakers, 49% of them in Africa. Some 89% of Quakers worldwide belong to ''evangelical'' and ''programmed'' branches that hold services with singing and a prepared Bible message coordinated by a pastor. Some 11% practice ''waiting worship'' or ''unprogrammed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metrication In The United States
Metrication (or metrification) is the process of introducing the International System of Units, also known as SI units or the metric system, to replace a jurisdiction's traditional measuring units. U.S. customary units have been defined in terms of metric units since the 19th century, and the SI has been the "preferred system of weights and measures for United States trade and commerce" since 1975 according to United States law. However, conversion was not mandatory and many industries chose not to convert, and U.S. customary units remain in common use in many industries as well as in governmental use (for example, speed limits are still posted in miles per hour). Unlike other countries, there is no governmental or major social desire to implement further metrication. Although customary units are used more often than metric units in the U.S., the SI system is used extensively in some fields such as science, medicine, electronics, the military, automobile production and repai ...
