 	- **Who**: Created by Douglas C. Schmidt at Washington University, St. Louis.
 	- **Why**: To provide a portable, reusable C++ framework for building high-performance networked and real-time systems using well-known design patterns (Reactor, Proactor, Active Object).
 	- **When**: Development started in the early 1990s. Widely used in telecom, defense, and financial systems.
