From The History of Clark County Ohio, (1881)
JAMES W. NELSON, M. D., physician, Springfield. Dr. Nelson was born in the city of Springfield August, 1850. When about 5 years old, he moved to Lagonda with his parents; he received his primary education in the school of said village, and remembers well the old woolen factory, grist and saw mills which have several years since passed away, and given place to the large manufacturing establishments of Warder & Co. At the age of 12 years, he began to work in said shops, where he worked four years; when, on the removal of his parents into Springfield, he entered the employ of Whiteley, Fassler & Kelly, and worked in what is now known as the “old Champion shop," where he worked three years, when he returned to Lagonda, and began working for Warder, Mitchell & Co., with whom he worked one year. Then after a short sojourn in Hamilton Co., Ohio, returned to Springfield. About this time his mother was very anxious he should go to school He was reluctant to start, thinking, like a great many other young men, "that he was too old to go to school" But, after considerable persuasion, attended a private school taught by Mr. Morton. After attending this school one term, went to Wittenberg
College, taking a select course; and then read medicine with Dr. Buckingham, of Springfield. During the winter of 1874—75, he took the first course of lectures in the Starling Medical College of Columbus, Ohio. He was married, in April, 1875, to Mary Mowatt, and during that year removed to Illinois, where he began the practice of medicine. In January, 1876, at the request of his wife and mother, returned to Springfield, Ohio, and, in the spring of that year, moved to Clifton and opened an office, where he remained about one year, when he returned to Lagonda, the place of his boyhood days, where he is at present practicing his profession in connection with his drug store. During the winter of 1877-78, he attended the Medical College of Columbus, where he received his diploma. He is a member in good standing; also P. G. of Ephraim Lodge, No. 146, I. O. O. F. Mr. Nelson so far has been successful in his practice, and is a young man of honor and good moral habits.
