## Summary  
Andreas Reuter is a German computer scientist and university professor best known for his pioneering research on database concurrency control. He is a professor at the University of Stuttgart, a Fellow of the Association for Computing Machinery (ACM), and has mentored a generation of computer‑science PhDs.

## Biography  
- **Born:** 31 October 1949, Brandis, Germany  
- **Nationality:** German  
- **Education:** Ph.D. in Computer Science, Technical University of Darmstadt (doctoral advisor: Theo Härder)  
- **Known for:** Fundamental contributions to database concurrency control and service to the computing community  
- **Employer(s):** University of Stuttgart (primary); Heidelberg University (affiliation)  
- **Field(s):** Computer science – database systems, transaction processing, concurrency control  

## Contributions  
Andreas Reuter’s research has shaped the theory and practice of concurrency control in relational database systems. His work introduced robust algorithms that ensure correct transaction execution while maximizing parallelism, a cornerstone of modern high‑throughput databases. The impact of his contributions is reflected in the ACM Fellow citation (2019), which explicitly recognized “contributions to database concurrency control and for service to the community.” Beyond his own publications, Reuter has supervised more than a dozen doctoral students—including Ursula Thalheimer, Friedemann Schwenkreis, and Wolfgang Becker—who have continued to advance database research and industry practice. His collaborations with the ACM and participation in scholarly venues have helped disseminate best practices for transaction management worldwide, influencing both academic curricula and commercial database products.

## FAQs  
### Q: What is Andreas Reuter most known for?  
A: He is renowned for his seminal research on database concurrency control, which earned him the ACM Fellow distinction in 2019.  

### Q: Which university does he work for?  
A: He is a professor at the University of Stuttgart and also holds an affiliation with Heidelberg University.  

### Q: What major award has he received?  
A: In December 2019, Reuter was named an ACM Fellow for his contributions to database concurrency control and community service.  

### Q: Who was his doctoral advisor?  
A: His Ph.D. advisor was the German computer scientist Theo Härder.  

### Q: Has he supervised notable doctoral students?

## Why They Matter  
Reuter’s work on concurrency control addressed a fundamental challenge in database systems: how to allow multiple transactions to execute simultaneously without compromising data integrity. By devising algorithms that balance safety and performance, he enabled the scalability of today’s high‑transaction environments, from banking systems to cloud‑based services. His research has been incorporated into textbook curricula and influenced the design of commercial database engines, directly affecting the reliability of countless applications. Moreover, through his mentorship of dozens of Ph.D. students, Reuter has propagated his expertise across academia and industry, ensuring that his methodological innovations continue to evolve. Without his contributions, modern database systems would likely be less efficient and more prone to concurrency‑related errors.
