Who is recognized as the first Radiology Instructor?

The first Radiology Instructor is recognized as Raper, who played a foundational role in dental radiology education. Raper's contributions helped to formalize the training and practices surrounding radiographic techniques, ensuring that future generations of dental professionals were equipped with the necessary skills and knowledge to safely and effectively use X-ray technology. This recognition stems from his efforts in standardizing radiographic methods and his involvement in educational efforts related to radiology in dentistry.

The other figures mentioned, while significant in the field of radiology — such as Roentgen, who discovered X-rays, and Kells and Rollins, who made important contributions to dental radiography — do not hold the specific title of the first Radiology Instructor in the context of formal education and training. Raper's establishment of educational protocols and emphasis on instructing upcoming dental professionals marks his unique position in the history of radiology instruction.
