Secretary Samuel P. Langley studying and photographing birds in flight from a tower on the grounds of the National Zoological Park. Secretary Langley (third Secretary of the Smithsonian, 1887-1906), in establishing the Zoo in Rock Creek Park, had remarked on the suitability of the isolated spot for his astrophysical observatory. Although that arrangement never came to fruition, in 1901 he directed that two towers be erected in the park for flight observation experiments. During the years leading up to 1903, when Langley attempted flight with the aerodrome he designed, the Secretary was intently studying birds in flight.
