Aaron, the subject of this sketch, was born July 1, 1839, in Saegersville, Lehigh Co., Pa., where his early life was passed. He received his earliest education at the village school, anti later became a pupil of the leading school of Allentown, alter which he prosecuted his studies at Kingston, Luzerne Co., Pa. He early decided upon a professional career, and in 1859 began the study of medicine with Dr. David O. Mosser, Breinigsville, Lehigh Co., which was continued with Dr. D. D. Shade, of Steinsville, Pa. He attended lectures at the Medical College of the University of New York, and graduated from that institution in the spring of 1862. He first located at Germansville, Pa., and after a successful practice of two years removed to Saegersville, where he has since followed his profession. From the first Dr. Miller enjoyed an extended practice, which has also been successful and lucrative. Like most country practitioners he engages in a general practice, including such occasional cases of surgery as come under his observation. He is a close student, drawing his wisdom not less from experience than from intelligent reading of the standard works of the clay. The doctor was married in 1863, to Miss Sarah K., daughter of William Mosser, of Albany, Berks Co. 'Their children are Cora A., Peter W., Maggie S., Sophia K, and Franklin A. The doctor is in politics a Republican, but so exclusively devoted to his profession as to have little leisure for matters of public concern. He is the owner of a productive farm, and is also a director of the Sacgersvihle Slate Mining arid Manufacturing Company, and engaged in other business operations. He is in religion a member of the German Reformed Church, of Heidelberg.
