HERMAN A. GUEFFROY, M. D.

     If "He serves the Master best who serves humanity most," then there is no
class to whom we owe more gratitude than the self-sacrificing, devoted men whose
life work is the alleviation of suffering and the saving of life. To this worthy
class of men belongs Dr. Herman A. Gueffroy, of Salem, who is regarded as of the
ablest and most successful physicians in this locality. He was born in Dakota
territory in 1880 and is a son of John and Henrietta Gueffroy, who settled there
in 1879, the former being a farmer by occupation. The family remained there
until 1905, when they came to Salem, Oregon, where both parents died.
     Herman A. Gueffroy secured a good public school education and then entered
the medical school of Northwestern University, Chicago, from which he was
graduated with the degree of Doctor of Medicine in 1913. He served as interne in
the Chicago Lying-in hospital and afterward located at Frankfort, South Dakota,
where he was engaged in the practice of his profession until August, 1918, when
he enlisted in the Medical Corps of the United States Army. After the close of
the war he was honorably discharged and resumed his practice at Frankfort, where
lie remained until 1924, when he came to Salem, where he has since conducted a
general practice, though specializing in obstetrics, in which he has gained an
enviable reputation.
     On February 14, 1924, Dr. Gueffroy was united in marriage to Miss Amanda
Olson, of Frankfort, South Dakota. He is independent in his political views but
has always taken a keen interest in public affairs, having served as mayor while
living in Frankfort, South Dakota. He is a member of the Masonic order, the
Commandery and the Mystic Shrine. He maintains professional affiliation with the
Tri-County Medical Society. Because of his sterling character and consistent
conduct, as well as for his cordial and friendly manner, he has won a high place
in public esteem throughout the community in which he lives.
