The Nautilus Insurance Company (predecessor of the New York Life Insurance Company) was one of several insurance companies that sold policies to slaveholders to insure their slaves against damages or death. The company sold these policies for approximately two and a half years from 1845 until 1848, at which time the board of trustees voted to end the sale of such policies.
