George Andrew Davis Jr. (December 1, 1920 – February 10, 1952) was a highly decorated fighter pilot and flying ace of the United States Army Air Forces in World War II, and later of the US Air Force during the Korean War.
 Davis rose to the rank of major, and was promoted posthumously to lieutenant colonel and awarded the Medal of Honor for his actions in "MiG Alley" during the latter war.
 He was the only flying ace of the United States to be killed in action in Korea.
The National Association for Chiropractic Medicine (NACM) was a minority chiropractic association founded in 1984 that described itself as a "consumer advocacy association of chiropractors".
 It openly rejected some of the more controversial aspects of chiropractic, including a basic concept of chiropractic, vertebral subluxations as the cause of all diseases.
 It also sought to "reform the chiropractic profession away from a philosophical scope of practice and towards an applied science scope of practice."
 It stated that it was "dedicated to bringing the scientific based practice of chiropractic into mainstream medicine" and that its members "confine their scope of practice to scientific parameters and seek to make legitimate the utilization of professional manipulative procedures in mainstream health care delivery."
 "While the NACM is focused on furthering the profession, its primary focus is on the rights and safety of the consumers."
 The NACM was the object of much controversy and criticism from the rest of the profession.
 It quietly dropped out of sight and its demise apparently occurred sometime between May 30, 2008 and March 6, 2010.

Optometry is a health care profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease.
 Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles.
 Modern day optometry, however, has evolved through time so that the education curriculum additionally includes intensive medical training in the diagnosis and management of ocular disease in countries where the profession is established and regulated.
 Optometrists (also known as Doctors of Optometry in the US and Canada for those holding the O.D. degree or Ophthalmic Opticians in the UK) are medical professionals who provide primary eyecare through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases.
 Being a regulated profession, an optometrist's scope of practice may differ depending on the location.
 Thus, disorders or diseases detected outside the treatment scope of optometry are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are physicians that specialize in tertiary medical and surgical care of the eye.
 Optometrists typically work closely together with other eye care professionals such as ophthalmologists and opticians to deliver quality and efficient eyecare to the general public.

Van Davis (born Van Andrew Davis Jr.) was a professional American football defensive end.
 He was a member of the New York Yankees of the All-America Football Conference.
