Frederick S. C. Grayston, A. M., M. D., an able and scholarly physician of this city, is a native of England. He was born April 6, 1823, being the third son of Bartholomew and Lucy (Trott) Grayston, both of whom were also natives of England. His early life was spent at home with his parents, and after completing his academic studies, he became the assistant to his father, who by profession was an attorney. This mode of life not being congenial to his tastes he was apprenticed to a pharmaceutist of the London Pharmaceutical Society, where he studied pharmacy and practical chemistry. Subsequently he became the assistant to a practicing physician. Here his natural tastes and inclinations were encouraged, and he successfully pursued the various branches of medicine. In 1850 he emigrated to America. On reaching this country he contined (sic) westward, and on the 12th day of October found himself with his family in the village of Huntington. For the purpose of prosecuting his medical studies, early in the following spring he moved to Cincinnati and became the pupil of Prof. Lawson, of that city, attending private classes in the hospitals. In October of that year he matriculated in the Medical College of Ohio, attending a full course of lectures in that institution. He then returned to Huntington and entered upon his professional career in which he has been eminently successful. In 1860 he entered the Chicago Medical College, from which he graduated with prize honors, in March, 1861. In 1863 he entered Rush Medical College, of Chicago, and received from that institution the Ad Eundem Degree in the spring of 1864. In 1880 he attended the graduates' course in the Chicago Medical College. There he made the study of female diseases a specialty, and to these his attention has been more particularly directed ever since. In 1882 he took a course in the polyclinic department of the Bellevue Medical College, New York City. Upon the inauguration of the Ft. Wayne Medical College, in 1876, he was elected Professor of the Diseases of Children. Subsequently he occupied the Chair of Pathology, four terms, and, later on, was elected to the Chair of Theory and Practice of Medicine, which position he still retains. In 1864 he was appointed, by Pres. Lincoln, Examining Surgeon for Invalid Pensioners, retaining the position twenty years. In 1880 the degree of A. M. was conferred on him by Butler University, of Irvington, this State. He, at present, has a membership with the National Medical Association, the Indiana State Medical Society, the Huntington County Medical Society and he holds an honorary membership with the Grant County Medical Society. He was President of the District Medical Society during 1882 and 1883. He is an active, persistent and progressive worker and in all of his professional labors he has borne an influential and enviable part. He has contributed a number of valuable productions to different medical societies and his prize essay upon the subject of diphtheria has been extensively published. His marriage to Isabella Custance occurred in his native country May 1, 1849. Five children have been born to them as follows: Boston H. B., Sarah I., Charles E., Anna L. and Frederick W. The two daughters are deceased. The two eldest sons--sketches of whom appear below--are graduates of medical colleges and both are, at present, associated with their father in the practice of medicine. The youngest son, Frederick W., is a student in the High School of this city. Dr. Grayston is a Royal Arch Mason, and in politics is a Republican.
