Mr. Specter. What is your profession, sir?

Dr. Gregory. I am a physician and surgeon.

Mr. Specter. Would you outline your educational background briefly, please?

Dr. Gregory. I received a bachelor of science degree from the University of Indiana in 1941, and an M.D. degree in medicine from the Indiana University School of Medicine in 1944.

Following 1-year internship and a tour of duty in the U.S. Navy, I undertook 5 years of postgraduate training in orthopedic surgery at Indiana University Medical Center.

Upon completing that training I became a member of the faculty at Indiana University Medical School, and remained so until November of 1952, when I reentered the U.S. Navy for another 20 months.

In 1956 I was appointed professor and then chairman of the Division of Orthopedic Surgery at the University of Texas Southwestern Medical School, where I presently am.

Mr. Specter. Are you certificated by the American Board of Orthopedic Surgery?

Dr. Gregory. I am, in 1953.

Mr. Specter. What experience, if any, have you had with bullet wounds, Doctor?
