Dr. Emmerich was a scientist involved with the Manhattan Project. He was the father to "Huey" Emmerich and grandfather to Hal Emmerich.

Biography
Emmerich helped to work on the Manhattan Project, putting his whole life into that research. After seeing the results of his work, he began to suffer from a great deal of guilt, which he carried with him for the rest of his life. More guilt was added to Emmerich's life when his son was born on August 6, 1945 (the day of the Hiroshima bombings) as a paraplegic because of an abnormally shaped spine. His wife often used to tell his son that he saved countless American boys from his research, and because of this, he looked up to him, although his respect ended up turning into disgust for his father during the fifth grade after a Japanese transfer student showed him pictures of the aftermath of the Hiroshima bombings.

After Emmerich's death, his son and grandson would follow in his footsteps, involving themselves in weapons development research.

Behind the scenes
In Metal Gear Solid 3, Granin mentions a "friend in the United States" to Naked Snake, who was strongly suggested to be either the father or grandfather of Hal Emmerich. The photograph in Granin's office and a radio conversation between Snake and Sigint (following the pair's meeting) supported this. Character biographies leaked prior to the release of Metal Gear Solid 3 stated that the man in question was Hal's father, though the Metal Gear Solid 4 Database contradicted this by stating that it was the grandfather. This was later clarified in Metal Gear Solid: Peace Walker, when it was revealed that he was actually Hal's father, Huey.

Although Dr. Emmerich has never appeared in a Metal Gear Solid title, he has been mentioned seveal times in some of the games:
 * His work on the Manhattan Project was pointed out by Hal to Solid Snake in Metal Gear Solid.
 * His putting all of his life's work into the Manhattan Project was mentioned by Huey to Big Boss in Metal Gear Solid: Peace Walker.
