Rollin E. Becker (1910-1996) grew up in an osteopathic household. His father, Arthur D. Becker, D.O. was a prominent and respected osteopath, who served on the faculty with Dr. Andrew Taylor Still and later was dean of two osteopathic colleges. Rollin graduated from the American School of Osteopathy (later renamed the Kirksville College of Osteopathic Medicine) in 1934, and following a few years in Oklahoma, he moved to Michigan, where he practiced for thirteen years.

In 1944, after about a decade in Michigan, he met William Garner Sutherland, D.O. and in 1948, he first served on the teaching faculty at one of Dr. Sutherland's courses. Dr. Becker moved to Texas in 1949, where he practiced until 1989. Throughout that time, he continued to serve Dr. Sutherland and his work. Dr. Becker was the president, from 1962 through 1979, of the Sutherland Cranial Teaching Foundation, an educational organization dedicated to perpetuating the teachings of W. G. Sutherland.

In the years following Dr. Sutherland's death in 1954, Dr. Becker played a crucial role in keeping his work alive. He went on to inspire generations of osteopathic teachers and students.
