The texas chainsaw is not real but, there is sombody that is real in the story his name is Ed Gein here is some info i found about him.
Ed Gein is probably one of the most famous serial killers, though his known victims only numbered two. Yet it was his extra-curricular activities that launched several movies and many books.
Gein was born in Plainfield, Wisconsin, in 1906 to an alcoholic father and a domineering, god-fearing mother. A shy, lonely boy, Gein grew to be a shy, lonely, reclusive man. When Eddie was in his late twenties, his father died and Ed and his brother Henry took over the work on the family farm. Both boys remained bachelors their entire lives due to their mother's incessant rantings; women would never return their love and only their mother would ever truly care for them.
The farm was not at all profitable, it was a hard life for Ed Gein and things began to slip away when his brother Henry died fighting a brush fire. Mrs. Gein endured an incapacitating stroke in 1944, and Ed nursed her for a year before a second attack took her life in December 1945.
Ed Gein was alone for the first time, at the age of 39. In his solitude, Gein began to withdraw from society and reality. He started reading medical and anatomical texts and developed an interest in the female body for the first time in his life. His life became more and more bizarre as he left reality behind altogether. A Government subsidy he received was enough for him to stop working on the farm, but he performed some odd jobs for those around Plainfield, if needed. While many residents of Plainfield thought him to be a little odd, they figured he was just a lonely eccentric. Little did they know his solitude had changed this lonely loner into a full fledged maniac.
