JOHN D. MUSSER
John D. Musser, Sr., at the time of his death, July 24, 1900, was a well known merchant of River Junction, Iowa. His son, John D., our subject, succeeded his father and is at present engaged in the mercantile business at River Junction. Formerly the senior Musser was a farmer, and the farm which he occupied in Fremont township, and which he cultivated until 1875, is still known as the Musser homestead. John D. Musser, Sr., was a native of Pennsylvania, and his wife, Elizabeth Rayner, mother of our subject, was a native of England. The latter survived her husband nearly nine years, dying January 18, 1909. The elder Musser came to Johnson county with his parents when a child, and from that time his entire life has been lived in this county. Six children were born to John D. and Elizabeth Musser: Frank, living on the old homestead (see personal sketch); Sarah G., now Mrs. J. I). Decker, living in Pleasant Valley township; Jane E., now Mrs. M. S. Maxim; Mary R., now Mrs. H. W. Hilton, living in South Dakota; Joseph R.. married and farming in Fremont township (see personal sketch); our subject.
John D. Musser, Jr., was born in Fremont township in November, 1874. His first business was farming, an occupation which he followed until 1900, when he succeeded his father in the mercantile business at River Junction. He owns a beautiful farm in Pleasant Valley township, and is interested in farming as well as in other lines of business.
Mr. Musser was married in 1897 to Miss Mary J. Fountain, a native of Johnson county, whose parents were pioneers of the county. Six children have blessed their union: Harry, Josephine, Gladys (died at age of four years), Fay, Willis, and Neoma. Our subject is a democrat politically. His church affiliation is with the Methodist Episcopal.
