Our history

See where we’ve been, how far we’ve come and how we lead change.


  • Aetna Insurance Company organized an annuity fund to sell life insurance in 1850. In 1853, the Annuity department separates from Aetna Insurance and is incorporated as Aetna Life Insurance Company. The company’s first president is Eliphalet A Bulkeley. The “Aetna” name is retained to take advantage of the good reputation of the original Aetna. The name was inspired by an 11,000-foot volcano on the eastern shores of Sicily, Mt. Etna, which was the most active volcano in Europe.


  • Aetna hires its first full-time employee Thomas O. Enders.


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


  • Aetna begins offering participating life insurance policies, which paid dividends to policyholders just as the mutuals did, but gave Aetna the ability to better compete in the marketplace. 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.


  • Annual income tops $1 million. By 1864, Aetna increased its business 600 percent over 1861 levels. This rapid growth gave Aetna the financial stability to meet the stringent requirements placed on life companies in Massachusetts and New York.


  • 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.


  • 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. Aetna also built into new policies an emphasis on consumer-oriented items, such as nonforfeiture clauses and paying policyholder dividends after the first year rather than the fifth, as was generally done.


  • Eliphalet A. Bulkeley dies; Thomas 0. Enders becomes president.


  • Aetna increases its capitalization from $150,000 to $750,000


  • Aetna moves into its fourth office at 650 Main Street in Hartford, Connecticut. The new building serves as Aetna’s home office for the next 42 years.
  • Aetna President Morgan G. Bulkeley is elected governor of Connecticut. Bulkeley, the son of the first Republican speaker in the Connecticut Legislature, was a career politician on the Republican side. He had already been the mayor of Hartford for several terms, and would eventually wind up his political career as a member of the storied "Millionaires' Senate" of 1906, so named for the wealth of its members.


  • Aetna issues its first accident policy. With its entry into accident coverage, Aetna took its first step in a 30-year transformation from a monoline insurer to a company that offered a variety of coverages.


  • Aetna becomes one of the first stock insurance companies to enter the health insurance business. The new product was offered only to people holding or purchasing an Aetna life or accident policy.


  • Aetna begins offering liability coverage. As the nation's industrial base grew more complex, and the Progressive social reform movement gained political momentum, Aetna responds by organizing an Accident and Liability department in 1902 to handle employers' liability and workmen's collective insurance. This department became the cornerstone of the Aetna Accident and Liability Company in 1907. It later added protection against damage to horse teams, flywheel breakage, auto collision coverage, plate glass and burglary insurance, and surety bonds.


  • Aetna introduces its first corporate seal


  • The San Francisco earthquake hammers the insurance industry. Two hundred and forty-three insurance companies pay out more than $225 million in claims. This wipes out every dollar of profit American fire insurers had made over the previous 47 years. Twenty companies fail completely. Most make only partial payments under the tenuous assertion that most of the damage in the city had been caused by the earthquake (for which fire insurers were not liable). Nonetheless, the Hartford insurance companies would pay every claim in full. The Hartford Fire Insurance Company pays over $11 million. Aetna Insurance Company pays almost $3 million.


  • The company begins offering automobile coverage. Soon after, Aetna began aggressively developing related lines, such as collision and damage.


  • Aetna hires its first home office female employee, Julia Kinghorn, a telephone switchboard operator.


  • Aetna begins using Hollerith (keypunch) machines for tabulating. This is one of the earliest examples of Aetna's willingness to use technology to improve efficiency.


  • The company begins its first national advertising campaign.


  • Aetna introduces the industry's first combination automobile policy.
  • Several people insured by Aetna lose their lives on the Titanic.


  • Aetna forms a department to sell group life insurance, becoming one of the first insurers to write group coverage for businesses. This became the foundation upon which Aetna built its current health care business. The 1900s brought into the public consciousness the notion that employers were responsible for the safety of their workers.


  • The United States enters World War I. Aetna uses its financial strength to provide insurance needed to bond contractors involved in government construction. The company also helps fund the country's war effort by purchasing and selling millions of dollars of Liberty Bonds.


  • Aetna begins offering group disability policies.


  • Aetna appoints E.E. Cammack to run the Group department.


  • Morgan G. Bulkeley dies after 43 years as Aetna president. Under Bulkeley, Aetna experienced explosive growth. Its assets increased from $25.7 million in 1879 to $207 million, and premium income rose more than twenty-fold. Bulkeley is replaced by his nephew, Morgan B. Brainard. Under Brainard, Aetna revamped its agency system and rewrote its policies in simpler language.
  • The company advertises on radio for the first time
  • Aetna creates the first insurer-owned rehabilitation clinic for disabled workers, located in Syracuse, NY.


  • Aetna participates in the first Greater Hartford Community Chest fund-raising drive, starting its long tradition of giving.


  • Aetna appoints its first female officer, Dr. Marion Bills. Bills revamped the company's personnel policies within two years. She also introduced the Bonus Plan, a piecework sliding pay scale that was primarily applied to data processing departments.


  • The stock market crash kicks off the Great Depression. The inherent strength of the Aetna companies enables them to survive. Aetna manages the crisis by withholding dividend payments to shareholders from late 1932 to early 1934, reducing the workforce through attrition and cutting salaries by 10 percent. Aetna employees survive the Depression in relatively good shape.
  • Construction begins on the current home office at 151 Farmington Ave. At the time of its completion in late 1930, the structure is the largest colonial-style building in the world and is the largest office building in Connecticut.

  • Aetna bonds the construction of the National Archives Building in Washington, DC.


  • Aetna bonds the construction of seven U.S. Navy aircraft carriers. More than 1,600 Aetna employees served in the military during World War II. As it did in World War I, Aetna aids the war effort by throwing its substantial resources behind bond drives, raising millions for the war chest.

  • Aetna becomes the first insurer to advertise on television.


  • Aetna provides group coverage to the United Nations


  • Aetna bonds the construction of the United Nations headquarters in New York.


  • The Group department introduces major medical coverage, as a labor shortage coupled with a wage freeze make employee benefits one way employers can attract and retain workers.

The festivities featured Arthur Fiedler and the Boston Pops Orchestra, Harry James and his big band, Henny Youngman, and a congratulatory note from Vice President Richard M. Nixon. The birthday cake stands over 12 feet tall and weighs more than 200 pounds.
