The correct answer is C. Ketcham AH.

Albert H. Ketcham was born on August 3, 1870, and grew up in Whiting, Vermont. He graduated from the Boston Dental School in 1892, then moved to Colorado due to ill health. Inspired by the challenges

of the young profession of orthodontics, he chose to enter the Angle School of Orthodontia in 1902. As a deep thinker with an inquiring mind, Ketcham explored many of the philosophical and mechanical

problems, as well as the controversies of the profession of his day. He was one of the first to investigate root resorption, which continues to be a challenge today. He began to question some of Angle’s arbitrary pronouncements, causing Angle to attack him vehemently as a deviationist. He was smart enough to travel his own way from that time on. He worked hard to improve the American Society of Orthodontists (ASO) and served as their president in 1929. He was also instrumental in founding the American Board of Orthodontists (ABO), serving as its first president. In recognizing his lifetime of service, the Albert H. Ketcham Memorial is made to the individual member annually in recognition

of contributions made to the art and science of orthodontics. This award was meant to perpetuate and inspire the member as a leader in orthodontics following the example set by Dr. Ketcham. 

He pioneered dental radiography and was the first US orthodontist to install an x-ray laboratory. He delivered the first paper on x-rays in orthodontics to the American Society of Orthodontists in 1910. In 1926 he presented the first comprehensive data on root resorption.46 Although the earliest mention of root resorption in permanent teeth goes back to 1856, it was a report by Ketcham in 1927 (followed by a second in 1929) that finally aroused the concern of orthodontists.
