National Mutual Benefit was founded in January 1902 in Stoughton, Wisconsin, as the Beavers Reserve Fund Fraternity (BRFF). The idea of origination was envisioned by a few businessmen of Stoughton who believed that by combining the stability of “old line” insurance with the economy of the fraternal system, they could provide affordable insurance protection to average Americans. By the end of its first year in business, the BRFF had grown to 1551 members with $2,325,000 of life insurance in force.

Between 1916 and 1945, the organization merged with six other societies, and its name had been changed to National Mutual Benefit.

Through the years, National Mutual Benefit has modernized its systems, continuously improved its products, and constantly expanded the benefits of membership in the society. Today, NMB remains a dynamic, democratically governed, not-for-profit organization dedicated to the principles of fraternalism.
