Ingalls served in World War I; later as an editor of "Scientific American", he conducted a regular column on amateur astronomy. Educated at Cornell University, Ingalls was a life-time enthusiast in astronomy and telescope-making. In his editorial capacity he corresponded with hundreds of amateur and professional astronomers and other scientists in the U.S. and many other countries.
Correspondence; numerous copies of publications, reprints, clippings, etc., often related to the subject matter of the correspondence; also drafts and final versions for Ingalls's columns from "Scientific American" and other publications. The correspondence centers on problems of telescope construction, but not exclusively. In his editorial role and through many personal contacts, Ingalls developed friendships which were maintained through voluminous correspondence.
Russell W. Porter, who helped design and construct the telescope at Mt. Palomar, Calif., is a prominent correspondent in the collection.
Also includes rough sketches of telescope components; blueprints and many photographs of equipment and individuals.
