Lillian Segal

Arcturus expedition In 1925 Segal became a member of the Arcturus expedition that was led by William Beebe where her official title was "Associate in charge of special problems". She joined the ship in Norfolk, Virginia. Segal's role was to determine how the light is produced by the fish, and her plan was to use a spectroscope but the light produced by the fish was too dim to make this work, though they tried on dead fish that were collected during the expedition. To conduct her work on the ship, Segal had to devise her own chemical apparatus to collect fluids from the fish Photos from during the expedition present Segal working on deck and in the lab. The ship returned to land in August 1925.

In interviews given at the end of the expedition, Beebe credited the four women on the ship, Segal along with Ruth Rose, Marie Poland Fish, Helen Tee-Van, for his success. In 1928, William K. Gregory published the results of their work on the Arcturus expedition, with an acknowledgement to Segal's contribution on the project.

Later life Segal died on September 8, 1991.
