Aetna

In 1850, Aetna Insurance Company created a fund to sell life insurance. In 1953 the life and health divisions of Aetna separated. The company’s first president was Eliphalet A. Bulkeley.

In 1861, Aetna began offering participating life insurance policies, which paid dividends to policyholders and higher commission rates for agents. In 1865, annual revenue exceeded $1 million in revenue and continued to increase business and expansion, even in Massachusetts and New York where requirements for life companies were very stringent. Aetna was also one of the first companies to switch from half-notes to all-cash premium plans. Read more
