A. S. HANSEN, M. D.
Dr. A. S. Hansen, a specialist in the treatment of the eye, ear, nose and throat at Cedar Falls, was born in Denmark on the 5th of April, 1859, a son of Hans Hansen, who came to the United States in 1873. He made his way to Kenosha, Wisconsin, where resided some of his sons, who had preceded him to this country and had become prominent in the business life of that city. The father's death there occurred in the early '90s.
Dr. Hansen was fourteen years of age when he crossed the Atlantic to the new world. He had attended the government schools of his native country and continued his education in the public schools of Kenosha. At the age of eighteen he returned to Denmark, where he completed his education, spending some time as a student in Copenhagen and in a private college, from which he was graduated on the completion of a course in missionary work. He returned to the United States in 1883 and took up missionary Avork among the Danish people of this country, being pastor of the Danish Lutheran church at Cedar Falls for two years.
