Theodosius II (Latin: Flavius Theodosius Junior Augustus; 10 April 401 – 28 July 450), commonly surnamed Theodosius the Younger, or Theodosius the Calligrapher, was Byzantine Emperor from 408 to 450. He is mostly known for promulgating the Theodosian law code, and for the construction of the Theodosian Walls of Constantinople. He also presided over the outbreak of two great christological controversies, Nestorianism and Eutychianism.

Theodosius was born in 401 as the only son of Emperor Arcadius and his Frankish-born wife Aelia Eudoxia. In 408, his father died and the seven-year-old boy became Emperor of the Eastern half of the Roman Empire.

Government was at first by the Praetorian Prefect Anthemius, under whose supervision the Theodosian land walls of Constantinople were constructed.

In 414, Theodosius' older sister Pulcheria was proclaimed Augusta and assumed the regency. By 416 Theodosius was capable of ruling himself, but his sister remained a strong influence on him. In June 421, Theodosius married Aelia Eudocia, a woman of Greek origin. The two had a daughter named Licinia Eudoxia.

The Walls are an Irish rock band. They were formed in 1998 by two ex-members of The Stunning.

Brothers Steve and Joe Wall (previously of The Stunning) returned to Ireland after a two-year failed label stint in London. Their Camden housemate Carl Harms joined the band on guitar and keyboard duties. Drummer Rory Doyle joined soon afterwards. They set up their own label, Earshot Records (later changing it to Dirtbird Records) and recorded and released a string of singles. A remix of one of the album tracks, "Bone Deep", clicked with radio and became a nationwide hit. Many of the songs have featured on a number of TV series and feature films such as Bachelors Walk, Dead Bodies, Goldfish Memory and On the Edge (starring Cillian Murphy).

The Walls heard rumour of a second Slane Castle date for U2 (as the first concert had sold out in hours). They sent four copies of their album to the band. Bono loved it and offered The Walls a support slot. That day the band played to their biggest crowd to date – around 80,000 people. "To the Bright and Shining Sun" was their next single. That June they supported Red Hot Chili Peppers. They spent the next year gigging while building their own studio in Dublin.

Lars Brownworth, an author and former United States history and political science teacher at The Stony Brook School, is the creator of the top 50 podcast, 12 Byzantine Rulers: The History of the Byzantine Empire. This podcast was created on a whim by Lars and his brother, Anders Brownworth. Often mistaken for a college professor, Lars was, in fact, a high school history teacher at the time the podcast was produced.

On August 15, 2007 Mr. Brownworth announced that he had resigned from teaching in order to work on a book with Crown Publishing titled Lost to the West: The Forgotten Byzantine Empire that Rescued Western Civilization, which was published on September 15, 2009. He is currently working on a new podcast about the history of the Normans as well as a book on the Macedonian Emperors of Byzantium. He maintains a blog called Finding History where he responds to reader and listener submitted questions.

In August 2011 Mr. Brownworth returned to the classroom at La Lumiere School, a coeducational boarding school in La Porte Indiana

Theodosius Grygorovych Dobzhansky ForMemRS (Ukrainian: Теодосій Григорович Добжанський; January 24, 1900 - December 18, 1975) was a prominent geneticist and evolutionary biologist, and a central figure in the field of evolutionary biology for his work in shaping the unifying modern evolutionary synthesis. Dobzhansky was born in Ukraine (then part of Imperial Russia) and emigrated to the United States as a young man in 1927.

He published a major work of the modern evolutionary synthesis, the synthesis of evolutionary biology with genetics, in 1937.

He was awarded the National Medal of Science in 1964, and the Franklin Medal in 1973.

Dobzhansky was born on January 24, 1900 in Nemyriv, Russian Empire. An only child, his father Grigory Dobzhansky was a mathematics teacher, and his mother was Sophia Voinarsky. In 1910 the family moved to Kiev, Ukraine. At high school, Dobzhansky collected butterflies and decided to become a biologist. In 1915, he met Victor Luchnik who convinced him to specialize in beetles instead. Dobzhansky attended the University of Kiev between 1917 and 1921, where he then studied until 1924. He then moved to Leningrad, Russia, to study under Yuri Filipchenko, where a Drosophila melanogaster lab had been established.
