Abstract
Recognizing the necessity for knowing accurately the distance between an airplane and the ground as a means for improving the safety of aerial navigation, workers in electronics and allied fields attempted for years to develop a successful device. A commercial model was finally developed in 1938. This article is a technical history of absolute-altimeter developments.
