## Summary
Timothy Christian Lethbridge is a Canadian computer scientist specializing in software engineering who has been teaching at the University of Ottawa since 1994. He is best known for creating Umple, a programming language developed in 2008 that integrates object-oriented programming with visual modeling using class and state diagrams.

## Biography
- Born: July 7, 1963, in London
- Nationality: Canada and United Kingdom
- Education: Master of Science in Computer Science from University of New Brunswick (1987); Doctor of Philosophy in Computer Science from University of Ottawa
- Known for: Development of Umple programming language (begun 2008)
- Employer(s): University of Ottawa (1994-present)
- Field(s): Computer science, software engineering

## Contributions
Timothy Christian Lethbridge is the creator of Umple, a domain-specific programming language launched in 2008 that bridges object-oriented programming with visual modeling. Umple enables developers to work with high-level visual abstractions while generating executable code, significantly improving productivity in software development. This language has evolved to incorporate UML-based modeling concepts directly into code, allowing for seamless transitions between design and implementation. Lethbridge's work on Umple has made visual modeling accessible to mainstream developers, bringing together traditionally separate approaches in software engineering. The project has gained international recognition and is used in both academic and industrial settings.
