In 1937, Alfred Ehmert made the surprising observation that cosmic ray absorption in water is less than in air for same effective thickness. In 1938, Kulenkampff was the first to correctly explain this effect in terms of meson decay, and this then enabled Hans Heinrich Euler and Werner Heisenberg to calculate an improved figure for meson decay time.
