The American General Insurance Company was formed on May 8, 1926 by Gus Sessions Wortham in Houston, Texas.

Before starting American General, he worked at his father's insurance company, John L. Wortham & Son Agency, until his death in 1924.

[6] In 1953, American General hired life insurance veteran Benjamin N. Woodson as president.

It became the leading case on a board of directors' ability to use defensive measures, such as poison pills or buybacks, to prevent a hostile takeover.

[11] After the deal failed to go through, AIG announced plans to acquire American General for $23 billion in stock.

[12] American General would continue to operate under AIG as their life insurance and retirement services subsidiary.

[13] Corebridge was formed as a result of a spin-off of AIG's retirement, life insurance, and wealth management segments.
