The Beagle Boys are a group of fictional characters from the Scrooge McDuck universe. Created by Carl Barks, they are a gang of criminals who constantly try to rob Scrooge McDuck. Their introduction and first appearance was in Terror of the Beagle Boys, in Walt Disney's Comics and Stories #134, although in this story they only appear in the last frame and have no lines. They appear again in the next issue in a similar fashion, in The Big Bin on Killmotor Hill. They first get a more prominent role in the later story Only a Poor Old Man.

The Beagle Boys were originally created by Carl Barks, and made their first appearance in the 10-page story The Terror of the Beagle Boys (WDC #134) that was first published in November 1951. Although the Beagle Boys are only shown very briefly on the last page of this story, it is implied that Scrooge has known about them for a long time. The first story to feature the Beagle Boys in a major role is Only a Poor Old Man from March 1952, which serves as a template for virtually all future Beagle Boys appearances, and establishes them as a serious threat to Scrooge's fortune.

 Martin Luther (help·info) (10 November 1483 – 18 February 1546) was a German monk, priest, professor of theology and iconic figure of the Protestant Reformation. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He confronted indulgence salesman Johann Tetzel with his Ninety-Five Theses in 1517. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the Emperor.

Luther taught that salvation is not earned by good deeds but received only as a free gift of God's grace through faith in Jesus Christ as redeemer from sin. His theology challenged the authority of the Pope of the Roman Catholic Church by teaching that the Bible is the only source of divinely revealed knowledge and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood. Those who identify with Luther's teachings are called Lutherans.
