Some Notes on Pierre Frederic Ingold
and the work of E. Haudenschild
Anon (possibly G.A. Berner)
This short report (11 pages with 9 illustrations) was produced on the occasion of the 8th general meeting of the Swiss Society for Chronometry in 1932. It gives a biography of PF Ingold and discusses his work with automatic machinery. Ingold is important because his work may have influenced the design of machinery at Waltham. It also includes brief descriptions of clocks made by E. Haudenchild.
