Clarke Publishing Company MRS. EDNA E. CHRISTOFFERSON is regarded as one of Portland's expert X-ray operators and has done a vast amount of high-grade work in that exacting science, which is now one of the most important and dependable helps to successful medical practice. She has her own laboratory at 533 Morgan building and has made over one hundred and twenty-five thousand X-ray exposures. A native of Chicago, Illinois, she is a daughter of Martin and Mary (Eggert) Bissner. The family came to Oregon in 1878 and the father is still living here, the mother having passed away in 1928. Mrs. Christofferson received her educational training in a convent in Vancouver, Washington, and then became the wife of Silas Christofferson, an aviator, who was accidentally killed at Redwood City, California. In 1912 Mr. Christofferson created a sensation by flying from the roof of the Multnomah Hotel in Portland. He was the first man to fly from San Francisco to Los Angeles and was the first to fly over Mount Whitney, California. In 1918 Mrs. Christofferson took up the study of X-ray under Professor E. C. Jerman, who is considered the greatest authority on that science. She went to Providence Hospital, in Seattle, Washington, for her first practical training and later had three month's work in Good Samaritan Hospital in Portland under Ralph Walker. She then became associated with Dr. F. E. Diemer, with whom she did X-ray work for seven years. Mrs. Christofferson is a member of the Business and Professional Women's Club, the Aero Club of Oregon and is president of the Oregon Women's Revolver Club, the only organization of its kind in America. She is also a member of the United States Revolver Association and the Portland Revolver Club. She is state agent for Governor Pierce, is associate member of the parole board and special police officer, and she has been awarded the army expert medal and the police qualification expert medal. She is the proud possessor of six international trophies for shooting 22 and 38 caliber pistols and she also has the medal of the Oregon State Revolver Association. Hers is indeed a notable record such as perhaps can be claimed by no other woman of the entire country. In her chosen scientific field she has made continuous progress and belongs to the American Radiological Technicians Association, while for the past seven years she has been successfully conducting a school for the teaching of X-ray technique. She is a woman of strong individuality and gracious personal qualities and is greatly esteemed by all who know her.
