                        JAMES K. P. McCALLUM.

                        Among the representatives of Denver's bar are men capable of crossing swords in forensic combat
                        with the ablest members of the profession anywhere. Strong, capable and resourceful in the practice
                        of law is James K. P. McCallum, who located in Denver in 1908 and has since made his home in this
                        city. He was born in Davis county, Iowa, September 22, 1844, a son of Daniel and Parthena J.
                        (Birdwell) McCallum, the latter a native of Tennessee, while the former was born in North Carolina. Both
                        have now passed away. The father devoted his life to the occupation of farming and was very prominent
                        in political circles. Removing to the west, he served as postmaster of Troy, Iowa, and passed away in
                        1890 at Helena, Montana. His grandfather was a native of Scotland and came to America soon after
                        the Revolutionary war.

                        James K. P. McCallum was one of a family of eleven children of whom only three are yet living. He
                        pursued his early education in the district schools of Davis county, Iowa, and afterward attended Troy
                        Academy in that county. He was a youth of but eighteen years when in September, 1862, he
                        responded to the country's call for troops, enlisting as a member of Company E, of the Third Iowa
                        Cavalry, with which he served for three years. He was wounded in the right arm in a skirmish on the
                        Tallahassee river, Mississippi, on the 8th of August, 1864. When discharged he was holding the rank
                        of corporal. He participated in twenty-two different engagements, saw much active fighting and
                        rendered valuable aid to his country, proving a most valorous and loyal soldier. After being honorably
                        discharged in 1865 he returned to his Iowa home and soon afterward continued his education in
                        Monmouth College at Monmouth, Illinois. Later he became a student in the State University at Iowa
                        City, Iowa, where he pursued a law course, winning the LL. B. degree as a member of the class of
                        1874, in which he was a classmate of Joseph C. Helms, late of Colorado, and they both took honors at
                        the time of graduation. Mr. McCallum practiced law in Plattsmouth, Nebraska, for several years and
                        then removed to Huron, South Dakota, where he resided for eleven years, being recognized as one of
                        the able members of the legal profession in that state. He was chosen a member of the convention
                        that framed the state constitution of South Dakota in 1885 and later he removed to Colorado, settling
                        at Walden, Jackson county, where he resided for a time, giving his attention to the publication of a
                        paper and to prospecting and mining. He removed to Denver in 1908 although he had had frequent
                        business in the city for twenty years previous to that time. On permanently taking up his abode in
                        Denver he opened a law office and for a time was largely engaged in criminal law practice but is now
                        concentrating his efforts and attention upon commercial and other branches of civil law. He is
                        accorded a good clientage and his ability has won him wide recognition in professional circles.
                        Moreover, he possesses much mechanical skill and ingenuity and has devoted considerable time to
                        inventions.

                        In 1867 Mr. McCallum was united in marriage to Miss Sarah E. Boon, of Monmouth, Illinois, and to
                        them have been born two children. A. Boon, born in 1884, is now manager of the Conner Advertising
                        Agency and is a printer by trade. Jean is a mining engineer. He was graduated from the North Denver
                        high school and from the Colorado School of Mines and is in charge of an extensive mining property at
                        Patuca, Central America, owned and operated by an English syndicate. The elder son married Alice
                        Shippey, of North Park, Colorado, and they have three children, Marion, Ione and Cecil. Jean wedded
                        Sophie Page, of North Denver, a graduate of the North Denver high school, and they have three
                        children, James Lowell, Elizabeth and Duane.

                        Mr. McCallum was active in politics in his youth as a supporter of the republican party, but later he
                        became identified with the democratic party. He belongs to M. M. Crocker Post, No. 81, G. A. R., of
                        the Department of Colorado and Wyoming, and proudly wears the little bronze button that proclaims
                        him one of the veterans of the Civil war. He is a man of fine personality, his long white beard and hair
                        giving him a venerable appearance, but his activity shows that he yet possesses the spirit of youth and
                        to him may well be applied the lines of Victor Hugo:

                                               "The snows of winter are on his head,
                                              But the flowers of spring are in his heart."
