The island was mapped from aerial photographs taken by USN Operation Highjump, 1946–1947, and USN Operation Windmill, 1947–1948. It was named by the US-ACAN for Lt. Richard C. Holl, USNR, photogrammetrist with the Navy Hydrographic Office, who served as surveyor with the Operation Windmill parties which established astronomical control stations on Holl Island and along Queen Mary and Knox Coasts. Churchill Point is the north-western point of the island; it was named by the US-ACAN for Radioman Robert W. Churchill, USN, a member of the Wilkes Station party of 1958.
A 1,052 ha site comprising both Holl Island and neighbouring O'Connor Island has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 30,000 breeding pairs of Adélie penguins, estimated from 2011 satellite imagery. Other birds recorded as breeding in the IBA include snow petrels, Cape petrels, south polar skuas, Wilson's storm petrels and southern fulmars.[1]
