Notes:
Edward W. Maupin (1849-1907)^2,3 was the son of a physician, Dr. George W.O. Maupin². City directories show he ran a drug store at High Street near Court Street starting on or before 1872.

In 1900, Dews & Maupin took over the drugstore of George A. Kreiger in 1900⁴. I think this was probably the same Edward W. Maupin, and I think his partner was Julius N. Dews. According to city Directories, the store was called the "Portsmouth Pharmacy" at first, then later it was called "Maupin's Pharmacy", as Dews apparently dropped out¹.

Julius N. Dews (1872-1926)⁵ passed his exam and became a regular druggist in 1892⁶.
An article in the 1902 issue of Scientific American magazine said that J.N. Dews had invented a pill-making machine designed to cut a roll of material into the desired number of sections to provide the desired number of pills⁷.
