Shaver, F. A., Arthur P. Rose, R. F. Steele, and A. E. Adams, compilers. "An Illustrated History of Central Oregon." ("Embracing Wasco, Sherman, Gilliam, Wheeler, Crook, Lake, & Klamath Counties") Spokane, WA: Western Historical Publishing Co., 1905. p. 1049. ISAAC A. DUFFY who stands at the head of the Dulty Mercantile Company of Klamath Falls, is a well known business man of accredited ability, whose labors in this county have, for years past, won a success which is gratifying, indeed. He was born in Belmont county, Ohio, on January 12, 1860. His father, Barney Duffy, a native of Ireland, came to the United States when a boy and married Miss Elizabeth Hess, a native of Pennsylvania, of German extraction. He is deceased but his widow is still living in Macon county, Missouri. When a child our subject accompanied his parents from his native state to West Virginia, thence to Missouri, in which place he grew up and received his education. Then he engaged in the drug business, continuing the same for twenty years. At the end of that period, he determined to try the west and accordingly made the journey to Oregon. For a while the stock business employed his energies, his headquarters being on the Owyhee river. After that, we find him at Gray's Harbor in the general mercantile business. Then he moved to various sections and finally located in Palouse City, Washington. In 1897 he journeyed thence to Klamath Falls and being impressed with the location, opened a small general merchandise store. From the beginning he was successful and trade rapidly grew. Finally in 1901 he organized the Duffy Mercantile Company and erected a fine new building in one of the best locations of the city and stocked the same with a full line of dry goods, clothing, groceries, shoes, gents furnishings, crockery and hardware. The trade has increased in a remarkable degree and Mr. Duffy is considered one of the most skillful and enterprising merchants of this part of the state. In addition to this business he is interested in the boats that navigate the Upper Klamath lake which are doing a good business. In every way Mr. Duffy has shown himself to be an enterprising and progressive man and has labored assiduously for the improvement and upbuilding of the country. Every enterprise which is for the betterment of the country and the bringing in of improvements has been fostered and favored by Mr. Duffy. He stands well in the community and is a public spirited man and one of the leading citizens of the county. ******************* Submitted to the Oregon Bios. Project in June 2011 by Diana Smith.
