Lockley, Fred. "History of the Columbia River Valley, From The Dalles to the Sea." Vol. 3. S. J. Clarke Publishing Co., 1928. p. 528. HENRY ALVIN DEDMAN, M. D. An able physician and surgeon with a background of more than thirty years of practical experience and a financier of high standing, Dr. Henry Alvin Dedman is rightly termed one of Canby's most valuable citizens and has also figured conspicuously in public affairs. A native of Missouri, he was born in 1863 and in childhood came to Oregon with his parents, Dr. E. C. and Sarah E. (Paddock) Dedman, who settled at Clackamas in 1878. The father was a successful physician but retired soon after his migration to Oregon, in which state he spent the remainder of his life. Dr. Henry A. Dedman obtained his public school training in Oregon City and afterward entered the University of Oregon, from which he received the M. D. degree in 1896. Since 1897 he has maintained an office in Canby and in the intervening period his knowledge and skill have been increased by three postgraduate courses at the Chicago Polyclinic. Dr. Dedman is a general practitioner and draws his patients from a wide area. In 1906 he was instrumental in forming the Canby Bank & Trust Company, which established the first moneyed institution in this locality, and in 1914 the name was changed to the Canby State Bank. Later the same stockholders organized the First National Bank of Canby, and Dr. Dedman is now president of both institutions, following a policy which has promoted their growth and prestige. In 1898 Dr. Dedman married Miss Anna B. Armstrong, and they became the parents of two children: Craig, who was graduated from the Oregon Agricultural College in 1925 and is now connected with its pharmaceutical department; and Mildred E., who completed a course in the University of Oregon in 1924 and is a teacher in the Oregon City high school. Dr. Dedman's second union was with Miss Blanche Jobe, to whom he was married in 1917. Mrs. Dedman was born in Pennsylvania and made the journey to Oregon about 1910 to engage in educational work. The Doctor is an adherent of the republican party and foe a number of years was one of the councilmen of Canby. He also became mayor, giving to the municipality a progressive and beneficial administration. From 1917 until 1920 inclusive he represented his district in the lower house of the general assembly of Oregon and sponsored all constructive legislation. The Doctor has been a member of Canby school board for twenty-four years, and fraternally he holds membership in the Masonic lodge at Canby, of which he is past master; the Odd Fellows lodge of Canby, of which he is past noble grand, and is affiliated with the Benevolent Protective Order Elks at Oregon City, of which he is a charter member. The Canby Chamber of Commerce numbers him among its energetic workers and his professional affiliations are with the Portland City and County Medical Society and Oregon State Medical Society and the American Medical Association. Studious, industrious and resolute, Dr. Dedman has steadily advanced, reaching a field of broad influence and usefulness, and stands deservedly high in public esteem. ******************* Submitted to the Oregon Bios.
