Samuel Pierpont Langley, Secretary of the Smithsonian Institution, 1887 - 1906. Washington, Smithsonian Institution, 1907. 50 pages (many uncut), wrps, Sm 4to (6.5x9.5"). Text of memorial addresses by Andrew D. White LLD, (The Scientific work of Samuel Pierpont Langley) by Prof. E.C. Pickering, Director of the Harvard Observatory and (Langley's Contributions to Aerial Navigation) by Octave Chanute. Of equal importance is a 15 page detailed bibliography of Langley's publications in many different scientific fields. Very good condition.
