David Kriesel is a German computer scientist and data expert recognized for his contributions to data processing and automation. He is widely known in the tech community, not only for his professional roles but also for his investigative approach to data and technology issues. Kriesel earned a degree in Computer Science from the University of Bonn and is currently the Director of Global Process and Engineering DataScience at Procter & Gamble. His background combines technical expertise with a focus on real-world applications, which has shaped his career as an innovator in document processing, automation, and data extraction. One of Kriesel's most famous discoveries occurred in 2013 when he identified a significant error in the Xerox WorkCentre 7535 copier. This error caused the machine to substitute certain numbers with incorrect digits in scanned documents, leading to serious data integrity issues. His discovery, widely known as the "Xerox Scandal," highlighted the potential risks in automated document processing and underscored the importance of reliable data handling in corporate and public contexts.
