John Jordan Linderman, son of Henry Linderman, was born in 1787, in Orange county, New York, in the house built by his grandfather, Jacob. He had the best possible preparation for the profession which he came to adorn. He studied medicine in New York City under the most eminent teachers of their place and time -- the two Hosacks, father and son, and Valentine Mott, who laid the foundations for the present day medical colleges and hospitals of the American metropolis. For a half-century he cared for a large practice in Pike county, Pennsylvania, often making a daily journey of forty miles on horseback or twenty miles afoot in his professional rounds. He treated his poor patients with as much consideration as he did those who were able to recompense him, and his cheery geniality made him an ideal physician in the sick room. He was among the first to abandon the practice of blood-letting and to curtail the use of mercurial preparations, substituting remedies of his own, and achieving phenomenal success in the treatment of certain diseases, notably typhoid fever, which in that day was deemed well nigh fatal and beyond the skill of the physician. He was for many years a Mason, and past master of the lodge at Mauch Chunk, Pennsylvania.
