EDWARD CRONIN, M. D., Platteville; is a Pennsylvanian by birth, having been born in the city of Philadelphia Feb. 22, 1812; his earlier years were passed in that city. Arriving at the proper age, he entered the freshman class of the University of Pennsylvania, where he graduated in the literary department in 1842. Upon leaving the University, young Cronin immediately commenced the study of medicine with Prof. John K. Mitchell, of Jefferson Medical College. In 1844, the young student formed one of the graduating class at the above-named college, coming forth a full-fledged M. D. After receiving his diploma, Dr. Cronin started for the West, rightly conjecturing that the star of empire was setting in that direction. He first settled in Platteville, where he continued in practice until 1850, when attracted, as were others, by the golden tales of California, he started for the Western Slope. Reaching Sacramento during the terrible cholera epidemic, when the citizens were dying off at a rate of four or five hundred a week, the young physician turned his attention to the work in hand, remaining in attendance at the hospitals until the terrible scourge had passed over. He then went further up the country to the Frazier River, where, upon the north fork of this stream, he afterward discovered what turned out to be two good claims. He remained here until 1853, when he returned to "the States" and settled at Galena, where he remained until 1860, when he returned to Philadelphia and attended lectures at Jefferson College, during the winter of 1860-61. He then changed his residence to Platteville, where he remained until 1864. The year following found him practicing in Philadelphia. In 1867, the Doctor returned to the West and located at Mineral Point, including Platteville in his ride. In 1872, he changed his residence to Platteville, where he has since been engaged in practice. The services of Dr. Cronin are by no means confined to a local area, but the circuit of his labors extends far out into adjoining sections.
