Henry Morgan Jacocks Papers

Identifier: Ms-1992-008

Scope and Content

This collection contains the papers of Henry Morgan Jacocks (1878-1950), graduate of Virginia Tech (class of 1900) and assistant superintendent of the Mathieson Alkali Works in Saltville, Virginia. The collection includes correspondence, operation notes, printed materials, blueprintsm, and photographs.

While Jacocks' papers contain a small selection of correspondence and records pertaining to Mathieson's operation, they largely consist of trade publications (both promotional and instructional). The catalogs promote steel products as well as various pieces of machinery and other products. The instructional materials consist of manuals for specific pieces of machinery as well as general technical publications. Within the collection is also a set of undated drafting standards for the Virginia Iron and Bridge Company (Roanoke, Virginia).

The papers also include a set of approximately two dozen blueprints and drawings, mostly for parts and machinery to be used at Mathieson. Except where otherwise noted, the drawings seem to have been completed in-house (a few were drawn by Jacocks himself). Among the drawings is a 1914 aerial view of Mathieson Alkali Works.

Biographical Note

Henry Morgan Jacocks, son of Jonathan Henry and Mary Katherine Harrell Jacocks, was born in Durant's Neck, North Carolina on December 31, 1878. He graduated from Berkeley Military Institute in 1895 before attending Virginia Polytechnic Institute and State University. A general science student at Virginia Tech, Jacocks was president of the Thespian and German clubs, vice-president of the Maury Society and served as literary editor of the Grey Jacket and editor-in-chief of The Bugle. (A younger brother, Jonathan Wilbur Jacocks, also graduated from Virginia Tech in 1900.)

Together with his younger brother Jonathan Wilbur, Jacocks graduated from Virginia Tech in 1900. He was hired by the Mathieson Alkali Works in Saltville, Virginia as an assistant draftsman. During his 17-year career at Mathieson, Jacocks would eventually rise to the position of assistant superintendent.

Around 1919, Jacocks moved to Craddock, Virginia, where he worked briefly for the Portsmouth Cotton Oil Refining Company before establishing H. M. Jacocks and Company. Selling fuel, feed and fertilizer, the business closed in 1933, a victim of the Depression and a warehouse fire. Following the closure of his business, Jacocks worked for the Virginia State Highway Department before retiring in 1950. He died in an automobile accident on August 20 of that same year and is buried in Norfolk's Magnolia Cemetery.
