N. W. Isbell, the first county judge in this county, was selected by the legislature in 1855 as a member of the supreme court, and filled the position with honor and credit to himself and the state for several years, and was afterwards appointed judge of the district court during the Civil war, but resigned both positions on account of ill health. He was a very learned man and a profound lawyer. He greatly enjoyed the investigation of legal questions, possessed an acute and analytical mind, and one richly stored with the results of historical and general reading. In the practice he was not partial to jury trials, much preferring the presentation of legal questions to the court. He had quite an aptitude for affairs, and became successful as an enterprising railroad builder, projecting the old "Air Line" Railroad, the pioneer of the present route of the C., M. & St. P. Railway across the state. He left a comfortable estate to his family, dying about the year 1865. He was of small stature and insignificant in appearance, but with a large head, though small features. Indeed he very much resembled the Hon. Wm. H. Seward in face, head, and stature. He was rather of an irascible temperament and consequently easily thrown off his balance--but no member of the bar was more highly respected than was Judge Isbell for uprightness, honesty of purpose, general intelligence, deep reading in general literature as well as in the law; and his blameless life made him a beloved citizen. I omit further mention of Judge Greene as there is elsewhere in this work a lengthy sketch of him. Isaac Cook was born and raised in eastern Pennsylvania and became the possessor of a sound education as a basis for the legal studies he afterward pursued. He served quite a while on the district bench, and was there noted for the care, time, and fairness he devoted to the cases he was called on to hear and decide. His mind was not so quick or rapid in its movements as some others, but it was very accurate in its conclusions. He was a fine chancery and corporation lawyer, and no better pleader ever drew a petition than Judge Cook. He was for many years toward the close of his life general counsel for the predecessors of the C. & N. W. Railway Company and the Iowa Railroad Land Company in the state of Iowa. Though he had an office first in Marion and then in Cedar Rapids, he always lived on his farm just south of the former place, in a plain, comfortable brick house. He was a broad shouldered, stock-built man of a dark complexion, and chewed an immense quantity of tobacco. He had, we believe, more practice in the supreme court of the United States than any other lawyer in Iowa in his day.
