The National Mutual was formed in 1896 by the merger of the National Life Assurance Society and the Mutual Life Assurance Society. It was notable for the Chairmanship of John Maynard Keynes between 1921 and 1938 when he developed the concept of active investment of its fixed interest portfolio, and investment in equities, long before the post-war “cult of the equity”. The National Mutual was demutualised in 2001 and the business transferred to G E Capital. Hisstory The two societies The National Life Assurance Society was formed as a company in December 1830. After a successful period in the 1830s, the growth in new business declined in the 1840s. In response the directors decided to convert to mutual status in 1847.

As with the National, the Mutual Life had also expanded regionally and had seven branches at the time of the merger. National Mutual and Maynard Keynes The priority post-merger was consolidation. The number of British branches was reduced to eight, and of the overseas agencies, only the profitable Mauritius was retained. It was not until 1906 that sums assured regained the combined level of the merged parties. John Maynard Keynes joined the Board in 1919, becoming Chairman 1921. Nicolas Davenport, a director from 1932 to 1969, wrote that the Board “contained some outstanding and unconventional intellectuals.; as well as Keynes they included Oswald Falk, Keynes’ stockbroker and close collaborator, and Walter Layton, 1st Baron Layton, editor of the Economist.
