E. Brown Industries was a business active in an alternate 1986, likely founded by First Citizen Brown. The company was housed in a small building sandwiched between two larger ones: the Citizen Reading Room and The Combformist.
The location was originally the site of Hill Valley's speakeasy in 1931 before Edna Strickland burnt it down. The building was rebuilt in February of 1932.
First established in 1945, E. Brown Industries built many of the inventions (including the electric cars) used by Citizen Brown and Edna to maintain peace in Hill Valley.
It is likely to be the alternate version of Doc Brown's Dr. E. Brown Enterprises that existed in 1985 and was displayed on the side of Doc's multi-step truck.
