GYLLENHAMMAR, M. D., of Gayville, Yankton county, was born in Sweden, on the 8th of February, 1857, being a son of Lars G. and Catherine M. (Samuelson) Gyllenhammar. From 1632 to the present time the subject's ancestors and himself have been noblemen in their native land, the Doctor's name, with the other members of the family, being registered in the noblermen's calendar at Stockholm, Sweden. Mrs. Anna Carlson, the Doctor's sister, who is his housekeeper, was widowed in Sweden, her husband having been a civil engineer. The Doctor was reared in his native land and his more purely literary education was secured in Linkoping College, where he continued his studies until he had completed the prescribed course of the college. About the year 1882 he took up the study of medicine and surgery, under most effective preceptorship, and in 1884 he emigrated from the far northland to the United States, locating in the city of Duluth, Minnesota, where he continued his technical studies under the direction of Dr. W. H. McGee, and while a resident of that city he also familiarized himself with the English language, so that he became well qualified for taking up his active labors in the country of his adoption. In the autumn of 1887 the Doctor was matriculated in the College of Physicians and Surgeons in the city of St. Louis, Missouri, where he completed the prescribed course, being graduated as a member of the class of 1891, and receiving his degree of Doctor of Medicine on the 10th of March of that year. He passed the ensuing summer in that city and in the autumn removed to Sioux City, Iowa, where he built up a successful practice, continuing to there follow his profession until the autumn of 1894, when he came to South Dakota and located in the city of Yankton, where he was engaged in practice for the ensuing three years, at the expiration of which he came to Gayville, which has ever since been the field of his earnest and successful endeavors in the work of his noble profession, in which he has gained marked prestige and the concomitant confidence and esteem of the community. Since coming to South Dakota Dr. Gyllenhammar has served about five years as a member of the board of pension examiners for Yankton county, and he is held in high regard by his professional confreres in the state, while his ability and pleasing personality have brought to him a representative support in his chosen field of labor. In politics he accords a stanch support to the Republican party and his religious faith is that of the Lutheran church. He is a member of the South Dakota State Medical Society, the Sioux Valley Medical Association and the American Medical Association, while fraternally he is identified with the Knights of the Maccabees and the Mutual Benefit Association. He is also president of the Yankton District Medical Association. The Doctor is the owner of a pleasant and well-appointed home in Gayville, in which he has a large library of well-selected books, both professional and scientific. The Doctor is not married, and his sister presides over the domestic affairs of his pleasant home, while in the family circle are two adopted children, George and Hilda Heloise.
