## Contributions
Phyllis Fox made significant contributions to computer science through her work on programming languages and simulation systems. Her most notable achievement was her involvement in the development of DYNAMO (DYNAmic MOdels), a simulation language created in the late 1950s at MIT. DYNAMO was designed to model and simulate complex dynamic systems, particularly in industrial and economic contexts. The language used a visual notation system that made it accessible to non-programmers, helping to democratize the use of computer simulations. Fox's work on DYNAMO helped establish simulation as a practical tool for analyzing complex systems, influencing fields ranging from industrial engineering to urban planning. Her contributions extended beyond DYNAMO to include work in artificial intelligence and computer programming education.
