Martin Marietta Corporation was an American company founded in 1961 through the merger of The Martin Company and American-Marietta Corporation. The combined company became a leader in chemicals, aerospace, and electronics. In 1995, it merged with Lockheed Corporation to form Lockheed Martin. The Martin Co. in Baltimore, however, retained that name for some time as a division of the new corporation.^{[citation needed]}

In 1982, Martin Marietta was subject to a hostile takeover bid by the Bendix Corporation. Bendix bought the majority of Martin Marietta shares and in effect owned the company. However, Martin Marietta's management used the short time separating ownership and control to sell non-core businesses and launch its own hostile takeover of Bendix (known as the Pac-Man defense). The end of this extraordinarily bitter battle saw Martin Marietta survive; Bendix was bought by Allied Corporation.

John Mark is a character in the New Testament. According to William Lane, an "unbroken tradition" identifies him with Mark the Evangelist. John Mark is mentioned several times in the Acts of the Apostles. The first mention is in Acts 12:12, when Peter is coming to his mother's house:

When this had dawned on him, he went to the house of Mary the mother of John, also called Mark, where many people had gathered and were praying.

John Mark himself appears a bit later in the same chapter, in Acts 12:25, as the travel companion of Saul (Apostle Paul) and Barnabas:

When Barnabas and Saul had finished their mission, they returned from Jerusalem, taking with them John, also called Mark.

John Mark is mentioned soon after the Council of Jerusalem in Acts 15:37-41. Paul (Saul) does not have a too flattering impression of his former associate, arguing over him with Barnabas in Antioch:

Barnabas wanted to take John, also called Mark, with them, but Paul did not think it wise to take him, because he had deserted them in Pamphylia and had not continued with them in the work. They had such a sharp disagreement that they parted company. Barnabas took Mark and sailed for Cyprus, but Paul chose Silas and left, commended by the believers to the grace of the Lord. He went through Syria and Cilicia, strengthening the churches.
