Optics in the early forties at the Harvard College Observatory
The author appreciates the opportunity to recall a few of the development efforts having to do with optical instrumentation during World War II at the Harvard College Observatory nearly 47 years ago. Except for the National Defense Research Committee (NDRC) Section 16.1 Summary Technical Volume (Columbia University Press, 1946), nothing has been published formally concerning quite substantial efforts at the Cambridge, Mass., observatory. Presentations, accompanied by slides and minor exhibits, have been made in recent years at local meetings, including the New England Local Section of OSA, the Amateur Telescope Makers of Boston, and the American Astronomical Society, Division on History.
