The Manhattan Project was started in 1942 to develop the first nuclear explosive for use against the enemies of the U.S. In July 1943, Dr. James Albrecht, one of the project scientists, was accused of spying for the Germans. Albrecht's coworkers noted in interviews that the man "stopped talking to anyone" and "seemed especially aloof, even for a scientist." Just days before his trial, Albrecht disappeared, leaving a wife and two children.
On November 17, 1998, Albrecht suddenly showed up at his younger son's home in Springfield, New Mexico. Upon realizing that the man was his father, Ethan Albrecht, at the time 81 years old, invited him in and tried to figure out what happened. However, within hours of Dr. Albrecht's reappearance, FBI agents arrived and took him away, to his son's protest.
In an interview with a local newpaper, Ethan noted that "Dr. James Albrecht hasn't aged a day. He looks as young as my son." The scientist also seemed to suffer from amnesia, constantly asking where his wife was and when his trial is. To this day, the government denies that Albrecht ever existed.
Dr. James Albrecht was 68 years old when he was invited to join the Manhattan Project.
