The following obituary is found in the May, 1938 issue of American Rifleman magazine.
With the death of R.F. Sedgley at his home in Philadelphia on March 29th, there passed out of the shooting world one of its unusual figures. Essentially a master mechanic and administrator, rather than a ballistician, he took keen interest in the performance of others on the target range, but never engaged in serious target shooting himself. On the other hand, he probably fired more rounds of ammunition of assorted types and calibers in the course of a year than do the majority of our dyed-in-the-wool shots. In an era when the individual arms manufacturer had practically disappeared, giving place to mass production by large corporations or to highly specialized custom-built barrel and stock-making, R. F. Sedgley developed a business which typified the spirit of Eliphalet Remingon, Samuel Colt, and those other pioneers of the American arms industry who were responsible for the golden era of development in American firearms. His passing will be sincerely regretted by a host of business and personal friends throughout the States.
