Richard Quirin

After the men were recruited, they were given pseudonyms and false stories to blend in as they returned to America. Quirin's new identity was Richard Quintas, a Portuguese man who moved to Upstate New York from Lisbon when he was three. He was considered by Kappe to be a "cool, cruel man who would not hesitate to kill anyone to accomplish the mission's objectives." On 13 June 1942, Quirin was one of the first four to come to America as he, George John Dasch, Heinck, and Ernst Peter Burger landed on American soil on a U-boat. Several days later, when Dasch turned himself in to the FBI, he named Quirin as one of the "true believers" of the operation. On 20 June, Quirin was the first to be arrested, FBI officers surrounding him as he tried to escape.

At the trial, Quirin took the stand after Heinck. He stated that he did not know the purpose of Operation Pastorius, and was just interested in returning to the United States. However, a cross-examination showed that Quirin saw himself as a loyal Nazi and had made no effort to get out of the operation. Quirin was emotionless as he was sentenced to death, only displaying sentiment when telling a guard that he wanted his contacts to know Dasch had "ratted" him out. Quirin and the five others were electrocuted on 8 August 1942, and buried in a potter's field with numbered graves.

Richard Quirin (26 April 1908 – 8 August 1942) was a German agent executed as a spy for Nazi Germany in World War II. He was one of eight agents involved in Operation Pastorius, and gave his name to the Supreme Court decision on the trial, Ex parte Quirin.

Born in Berlin in 1908, Quirin moved to the United States in 1927, living in Schenectady, New York. He worked as a mechanic during this time for General Electric. He lived in the United States from 1927 to 1939, and was a member of the German American Bund, as well as an open supporter of the Hitler regime. In 1939, Quirin and his wife returned to Germany. Upon his return, he got a job with Volkswagen. He worked with Heinrich Heinck at the plant in Braunschweig, and the two became the first recruited by Walter Kappe, the publisher of the Bund newspaper Deutscher Weckruf und Beobachter, for what became Operation Pastorius.
