1857

• Eliphalet A. Bulkeley stops a move to liquidate the company during an economic downturn.

1861

Aetna launches its new product with an aggressive promotional effort, which included higher commission rates for agents. This shift in strategy caught the industry by surprise. With the outbreak of the Civil War, many companies were thinking of retrenching, not expansion. But the devastation of the battlefields combined with a prosperous wartime economy sparked a surge in life insurance purchases.

1865

1867

• Aetna issues its first farm mortgage loan. By 1872, Aetna had 27 percent of its assets in farm mortgages. From that start, the company rose to become one of the two largest national firms in the farm mortgage field. By 1924, Aetna had 43 percent of its assets — $94 million — invested in the breadbasket of the country.

1868

• Aetna radically alters its business practices and hires its first actuary. It also abandons the half-note premium system, a widely used insurance standard. An all-cash premium plan is introduced, making Aetna one of the first companies to switch from half-notes.
