Small archive of material related to John Hays Hammond Jr. including signed letters and a detailed biographical article by Janet Mabie

[ Gloucester Massachusetts and others ]: [ self published ] 1928-1935. First Edition. An archive of material related to American Inventor John Hays Hammond, Jr. The archive includes 4 letters to Janet Mabie (of Eaton Centre, New Hampshire) all from 1935. 2 comment on a Mr. Lear "who curiously enough is in the same situation that I am in regard to the Navy and foreign patents. Perhaps we may be able to work together to break up this ridiculous threat upon the part of the Navy Department." The other 2 related to Miss Mabie gathering notes for "magazine use" and Hammond setting up a meeting between Mabie and Herbert Stone of Yachting magazine.

In addition to these letters, there is an 8 page carbon typescript (8 1/2 x 11 inches) about Hammond by Mabie that is quite interesting, giving insights into Hammond as a person and inventor. It is a fascinating read, and no doubt would add (if not published, which we have not been able to confirm one way or the other) to the portrait of Hammond known today.

Lastly the archive contains 2 black and white photographs of portions of Hammond's Castle in Gloucester Mass, called Abbadia Mare. Hammond built this eclectic mansion, which stands still today as a museum. Near Fine. [24510]


Hammond was an American Inventor with a large number of patents, second only to Edison himself. His work was very eclectic, although he was perhaps best known for his work in radio controlled operation of various kinds. Some have termed him the Father of Radio Control.
