Henry Draper
After his untimely early death from double pleurisy, his widow Mary Anna Draper funded the Henry Draper Medal for outstanding contributions to astrophysics and a telescope, which was used to prepare the Henry Draper Catalog of stellar spectra. This historical Henry Draper telescope is now at the Toruń Centre for Astronomy (Nicolaus Copernicus University) at Piwnice, Poland. The small crater Draper on the Moon is named in his honor.
