Samuel Stillman Berry (March 16, 1887 – April 9, 1984)[1] was an American marine zoologist who specialized in cephalopods.

Berry was born in Unity, Maine,[2] but the family home was the Winnecook Ranch in Montana, which had been founded by his father Ralph in 1880.

[3] This was the last paid employment he ever held in academia—all his later studies and expeditions were financed by the profits from the family ranch in Montana.

[1] From November 1946 to December 1969, Berry published his own journal, Leaflets in Malacology, which primary contained articles which he had written himself.

[4] Despite his independent status, he became a renowned malacologist, publishing 209 articles and establishing 401 mollusc taxa.
