IRL Name: 
Gary Kildall

Gary Kildall is an American computer scientist and microcomputer entrepreneur who was noted for creating CP / M operating system first industry standard. He was born on May 19, 1942 in Seattle, Washington.

He died on July 8, 1994 where he fell at a Monterey, California, biker bar and hit his head.

In March 1995,he was honored by the Software Publishers Association (now the Software and Information Industry Association) for his contributions to the microcomputer industry:

-Introduction of operating systems with preemptive multitasking and windowing capabilities and menu-driven user interfaces.
-Creation of the first diskette track buffering schemes, read-ahead algorithms, file directory caches, and RAM disk emulators.
-Introduction of a binary recompiler in the 1980s.
-The first programming language and first compiler specifically for microprocessors.
-The first microprocessor disk operating system, which eventually sold a quarter of a million copies.
-The first computer interface for video disks to allow automatic nonlinear playback, presaging today's interactive multimedia.
-The file system and data structures for the first consumer CD-ROM.
-The first successful open system architecture by segregating system-specific hardware interfaces in a set of BIOS routines.


Founder of Digital Research Inc (DRI).

Developed the first high-level programming language for microprocessors, PL/M.
