- Albree, G. Norman
- Description
- This is Norman Albree's pilot model for a one-sided logarithmic chart. It is white paper on a wooden disc painted black. There is a clear celluloid indicator that pivots at the center and is cushioned on purple felt. The scale permits readings of logarithms from 10,000 to 100,000. The instrument is marked at the center: ALBREE TRULOG SPIRAL (/) G. NORMAN ALBREE (/) BOSTON. Inside the fifth ring of the spiral is marked: ©1945.
- George Norman Albree (1888–1986), the inventor and donor, attended Amherst College with the Class of 1911 and graduated from Dartmouth in 1912. He is best known for designing the first monoplanes purchased by the U.S. Army in 1917. However, after testing, the military deemed the aircraft too unreliable and slow and declined to order a production run from Albree's employer, the Pigeon Hollow Spar Company of East Boston, Mass.
