Otto Krebs

Background
Otto Krebs was a pseudonym.

In 1948 an unknown man identifying himself as Erich Radek travelled to Rome where, with the assistance of the Catholic Church, he acquired the new identity and travelled to Syria and, eventually, Argentina where he died in 1983.

Appearance
"Otto Krebs" provided cover for the real Erich Radek to become an intelligence asset for the United States.
