Tim Paterson is an American computer programmer and software developer best known for his work on the MS-DOS operating system. In the early 1980s, he created a system called QDOS (Quick and Dirty Operating System), which was designed to be compatible with DOS and was eventually purchased by Microsoft. This acquisition played a significant role in Microsoft's rise in the personal computing market, as QDOS was later rebranded as MS-DOS.
