The personal papers of Wallace C. Sabine

The notebooks of Wallace Clement Sabine were discovered in 1975, and his consulting files were discovered in 1979. Both findings were reported [J. Acoust. Soc. Am. 61, 629–639 (1977); J. Acoust. Soc. Am. 69, 1–7 (1981)]. By chance, his personal papers were discovered recently and highlights from them are presented here with emphasis on his European activities from 1906 to 1917.
