Valtrep fits right in, we need another entry:
ca. 1970 - Valtrep influences the creation of FORTRAN (see 1957).
FLASH! I know what happened: Doc Brown left a page of a Valtrep listing
inside the DeLorean when Marty took it back to the 50's.
The page was stuck to the bottom of Marty's shoe when he exited the
DeLorean. It was picked up by Backus and inspired him to produce FORTRAN.
See, everything can be explained by pop culture.
