A. D. Long (b. 1858, Delaware County, Iowa) served as county judge of Hutchinson County and was a prominent real estate figure in South Dakota. After completing law studies at the University of Iowa in 1881, he practiced law in Iowa before relocating to South Dakota in 1884, where he engaged in real estate, insurance, and cattle breeding. In 1898, he settled in Tripp, focusing on real estate and insurance. A committed Republican, he was elected county judge in 1900 and re-elected unopposed in 1902. Long married Caroline B. Carpenter in 1890, and they raised four children: Wade, Ruby, Irving, and Gertrude.
A. D. Long, County judge of Hutchinson County and one of the prominent real-estate men of the state, was born in Delaware County, Iowa, on the 22nd of February, 1858, being a son of William H. and Abigail (Whitehead) Long, and the elder of their two children, his sister Hattie being now the wife of Dr. C. A. Bradley, of Beatrice, Nebraska. The parents of Judge Long were both born in Fort Wayne, Indiana, and both removed with their respective parents to Laporte County, that state, when they were children, being there reared to maturity and there married. Shortly after the consummation of their marital vows they removed to Delaware County, Iowa, as did also the parents of Mr. Long. He there purchased one hundred and sixty acres of government land, which constituted the nucleus of his present magnificent landed estate, which comprises sixteen hundred and eighty acres. He has attained a high degree of temporal prosperity through his well-directed efforts, principally in the raising and dealing in live stock and in land speculation of legitimate order. For the past five years he has leased his land and lived in practical retirement in Manchester, Iowa, being one of the honored and influential men of the state and one of its sterling pioneers. While a staunch advocate of the principles of the Republican party from the time of its organization, he has never sought official preferment, though he has taken a zealous part in the promotion of the party cause.
Judge Long was reared on the homestead farm in Iowa, and his early educational advantages were such as were afforded in the public schools. He then entered Lenox College, at Hopkinton, Iowa, where he was graduated as a member of the class of 1880. Later he completed a commercial course in the Upper Iowa University, at Fayette, and was matriculated in the law department of the University of Iowa, at Iowa City, being there graduated in 1881. For the ensuing three years he was engaged in the practice of his profession at Earlville, that state, and at the expiration of that period, in 1884, he came to Pierre, South Dakota, where for two years he devoted his attention to the real-estate and insurance business. He then went to the Black Hills, where he remained about six years, following various lines of enterprise. He then returned to his native county in Iowa and turned his attention to the breeding of blooded cattle from imported stock, the enterprise proving successful and gaining him marked precedence. In 1898 Judge Long came to Tripp, South Dakota, and established himself in the real-estate and insurance business, in which he has since successfully continued, his transactions having reached wide scope and importance. He has ever been an uncompromising Republican, and in 1900 he was elected to the office of County judge, for which position his professional training and natural mental characteristics eminently fit him, and so ably did he discharge the duties of the office that in the election of 1902 no opposing candidate was enlisted against him, his majority being about thirteen hundred votes. He is the owner of three hundred and twenty acres of land in Douglas County, two hundred acres in Delaware County, Iowa, and is known as one of the leading real-estate dealers in the state. He is a member of Square Lodge, No. 286, Free and Accepted Masons, at Earlville, Iowa, and of Mahogany Camp, No. 849, Modern Woodmen of America, at Delaware, that state.
In June, 1890, Judge Long was united in marriage to Miss Caroline B. Carpenter, of Earlville, Iowa, and to this union have been born four children, namely: Wade, Ruby, Irving, and Gertrude. Judge and Mrs. Long are prominent in the social life of the community and their pleasant home is a center of gracious hospitality.
