Thomas E. Kurtz, co-inventor of the BASIC programming language and the Dartmouth Timesharing System, has passed away. Kurtz and John Kemeny developed BASIC in the 1960s to provide a simple programming language for undergraduates. The language and the timesharing system had a significant impact on the development of personal computers and programming. Kurtz's work at Dartmouth and his contributions to the field of computer science have been widely recognized.
