- Helen Adams Keller (June 27, 1880 – June 1, 1968) was an American author, disability rights advocate, political activist and lecturer. Born in West Tuscumbia, Alabama, she lost her sight and her hearing after a bout of illness when she was 19 months old. She then communicated primarily using home signs until the age of seven, when she met her first teacher and life-long companion Anne Sullivan. Sullivan taught Keller language, including reading and writing. After an education at both specialist and mainstream schools, Keller attended Radcliffe College of Harvard University and became the first deafblind person in the United States to earn a Bachelor of Arts degree.
- Terrane (Wikipedia)
In geology, a terrane (/təˈreɪn, ˈtɛreɪn/; in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or “sutured” to crust lying on another plate. The crustal block or fragment preserves its distinctive geologic history, which is different from the surrounding areas—hence the term “exotic” terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton.
- Keller was born on June 27, 1880, in Tuscumbia, Alabama, the daughter of Arthur Henley Keller (1836–1896), and Catherine Everett (Adams) Keller (1856–1921), known as “Kate”.
- She [Helen Keller] died in her sleep on June 1, 1968, at her home, Arcan Ridge, located in Easton, Connecticut, at the age of 87.
