Advert for Legal & General from 1977.

Legal & General was formed by Sergeant John Adams and five other lawyers in June 1836 in a Chancery Lane coffee shop. Originally called the New Law Life Assurance Society, the society was restricted to those in the legal profession. The name was changed to Legal & General Life Assurance Society to reflect that policies were available to the general public but with share ownership restricted to those in the legal profession.

The group expanded in the UK and soon began to acquire overseas life assurance companies, purchasing a pensions business from the Metropolitan Life Assurance Company of New York in the 1930s.

In 1956 Life business was set up in Australia.

The society became a wholly owned division of Legal & General Group plc in the 1970s.
