This collection consists primarily of the correspondence, dated 1948 to 1952, of Milton La Salle Humason (1891-1972),
a staff astronomer for the Mount Wilson [& Palomar] Observatories,
known chiefly for his collaboration with Edwin P. Hubble in the field of observational cosmology. There are occasional personal
letters but these are few compared to the correspondence with the public, received and answered by Humason in his capacity
as Secretary of the Observatory.
Milton La Salle (his middle name has also been cited as Lasell) Humason was a staff
astronomer for the Mount Wilson [& Palomar] Observatories throughout his entire
astronomical career. Humason is remembered chiefly for his collaboration with Edwin P.
Hubble in the field of observational cosmology. Perhaps his most notable accomplishment,
however, was his rise from mule-driver and janitor at Mt. Wilson to the position of
astronomer with the lack of a high-school education.
