The BASIC programming language is 50 years old this year – it derives from Dartmouth BASIC:
Dartmouth BASIC is the original version of the BASIC programming language. It is so named because it was designed and implemented at Dartmouth College. The language was designed by John Kemeny and Thomas Kurtz as part of the Dartmouth Time Sharing System (DTSS) and was one of the first programming languages intended to be used interactively.
The above is a quote from the article on Wikipedia at http://en.wikipedia.org/wiki/Dartmouth_BASIC

A PDF of the manual for the Dartmouth BASIC from 1964 is available to view at http://web.archive.org/web/20120716185629/http://www.bitsavers.org/pdf/dartmouth/BASIC_Oct64.pdf
I just found this very interesting, since we are celebrating 30 years of the QL this year and SuperBASIC is such an integral part of the QL, so to find that the BASIC language is 50 years old this year as well is quite interesting.
