     JOHN M. COOPER, M. D., Deceased.  No work that purports to mention the pioneers and prominent citizens of Douglas county would be complete without reference to the well-known gentleman and professional man whose name initiates this article.  Dr. Cooper is certainly worthy to be numbered among the leading citizens of Douglas county and his memory is dear to all.  For many years he was county physician and during his residence here had a large practice, being one of the skillful and successful physicians of central Washington.
     John Cooper was born in Memphis, Missouri, in 1858, being the son of Joseph and Sarah (Worth) Cooper, natives of Pennsylvania, and of English and German ancestry, respectively.  After the primary training of the common school course, he matriculated in a leading college and in due course of time received his degree, then entered the medical department of the University of Iowa attending the same until his diploma was received.  He was a thorough and hard-working student and immediately after graduation began the practice of medicine in Defiance, Missouri.  After three years there, he went to Nebraska, settling in Holstein.  Thence, in 1889, he came to Douglas county, taking up the practice of his profession in Waterville.  He continued steadily in the same until March 4, 1903, when death claimed the good man and many were left to mourn his demise.  With proper ceremonies and in the presence of a vast concourse of friends his remains were laid to rest in the Waterville cemetery.  Doctor Cooper had three brothers, William Z., Perry, George W., and one sister, Mrs. Joseph Ingalls.
     In Bedford, Iowa, in 1882, Dr. Cooper married Miss Nancy E., daughter of Thomas M. and Katherine (Hays) Simons, natives of Virginia and Illinois, respectively, and pioneers in Iowa.  Mrs. Cooper has the following brothers and sisters: Ralph H., Thomas R., James N., John W., Burton L., Mrs. David C. Ellis, Mrs. Thomas Davidson and Mrs. Wilbur Freemeyer.  To Doctor and Mrs. Cooper the following children have been born: Astley Raymond, in Iowa City, on January 24, 1883, now a druggist in Waterville; Joseph Thomas, born in Defiance, Missouri, on February 7, 1885, and now a student; Leslie Zonas, born in Defiance, Missouri, on November 2, 1887.  Dr. Cooper was a member of the A. F. & A. M., the Modern Woodmen and the Eastern Star, and at his death these societies and individuals rendered lasting tribute to his memory as a man, brother, friend and physician.
