Who discovered the Turbo C?

Turbo C wasn't discovered. The C programming language was originally developed by Dennis Ritchie from 1969 to 1973, specifically to re-implement the UNIX operating system, but implementers were quick to adapt C for a wide variety of system-specific, low-level programming, thus an explosion of non-standard implementations began to appear. The C language was finally standardised in 1983 and many of the non-standard implementations were dropped or replaced. One of these early implementations was Wizard C by Bob Jervis. Borland Software Corporation purchased this software and released it under their "Turbo" brand name in 1987, but it failed to achieve the success of their flagship IDE, Turbo Pascal, and was eventually superseded by Turbo C++ in 1990. Embarcadero Technologies bought the Borland development programs and released the Turbo C and Turbo C++ compilers as freeware in 2006.
