Clement of Rome
Clement I, the bishop of Rome also called Clement of Rome and Clemens Romanus, is considered one of the Apostolic Fathers.
Liber Pontificalis believes that Clement of Rome had personally known Peter, and states that he wrote two letters (the second letter, 2 Clement is no longer ascribed to Clement) and that he died in Greece in the third year of Trajan's reign, or 100. A 9th century tradition says he was martyred in the Crimea in 102, tied to a ship's anchor and thrown overboard to drown, but earlier sources say he died a natural death. The Vatican's "Annuario Pontificio" (2003) cites a reign from 92 to 99. He is commemorated on November 23.
Clement is perhaps best known by a letter to the Church in Corinth, often called 1 Clement. This was most likely written in 96, and "most likely directed against immoral practices of prostitution connected with the Temple of Aphrodite. In the letter, Clement expresses his dissatisfaction with events taking place in the Corinthian Church and asks the people to repent for their unchristian ways." 
A second epistle, better described as a homily and written in the second century, has been traditionally ascribed to Clement, but recent scholarship discredits his authorship.
