Winfield Evans, PhD was born in Hanna, Oklahoma, January 23, 1923. "Skeeter" was his nickname shortened from the original "Skeezics," a cartoon character which was popular at that time. He got this name from his four older sisters who thought that Winfield was too big a name for such a little boy. 

Winfield served in the US Army in Italy where he was in the Signal Core. In 1945, Winfield enrolled at Texas Tech where he met Mary, fittingly enough, in a Physics Lab. They were married in 1947 and had 7 children, 5 girls and 2 boys.

After completion of an Electrical Engineering Degree in 1948, he enrolled at MIT where he worked on the installation of the 2 meV Van De Graff X-Ray Therapy unit at Massachusetts General Hospital and completed his Master's Degree in 1950. The Family moved to Oklahoma City where he worked for and attended the University of Oklahoma. Winfield earned his Ph.D. in Physics in 1966 and is claimed to have been the first Medical Physicist in Oklahoma. Winfield served as medical physicist at St. Anthony Hospital in Oklahoma City for 30 years.

Dr. Evans was a member of Society of Nuclear Medicine, President and member of the Board of Trustees the Southwestern Chapter SNM. He was a member of many organizations and served as a member of the Oklahoma State Radiation Advisory Committee from 1959 to his death in 1989. He was chairman of this committee from 1959 to 1965.

Winfield Evans has been characterized as:

• A caring man who was committed to helping the sick through his professional talents
• A scholar who held knowledge in high esteem
• A friend who was totally unselfish with his time to help others

"I will always remember Winfield as a good friend," said Dr. Vernon Ficken, adding, "When I needed his assistance, he would always respond, 'Sure, Vernon, I'll be glad to help you.' There was never a question or reservation about his helping or working with others. Certainly he had that same commitment to the Southwestern Chapter."

All Chapter members have benefited from Dr. Evans' contributions to nuclear medicine: from his doctoral work at the University of Oklahoma where he developed theoretical concepts of focusing collimator design, numerous Chapter responsibilities including President, outstanding work as a Medical Physicist, and his extensive support of the American Board of Science in Nuclear Medicine.
