Otto von Bismarck

Otto Eduard Leopold von Bismarck was born on April 1, 1815, in Schönhausen, a Junker estate in the Prussian province of Saxony. He rose through Prussian politics with a combination of strategic brilliance and ruthless pragmatism, engineering the unification of Germany through three wars and becoming the first Chancellor of the German Empire in 1871. He held the office for nearly two decades, dominating European diplomacy and reshaping the relationship between the state and its citizens.

By the 1880s, Germany's rapidly industrializing economy had produced a large, restive working class increasingly drawn to the Social Democratic Party. Bismarck responded with a dual strategy. He banned the party's organizations in 1878, while simultaneously building a system of social insurance designed to bind workers' loyalty to the state. Sickness insurance came in 1883, accident insurance in 1884, and the old-age pension in 1889. The message was calculated. The state, not the socialists, would provide for workers.

The original pension age was set at seventy, later lowered to sixty-five in 1916. Average life expectancy in Germany during the 1880s hovered around forty-five years for men. The pension was an actuarial bet. Most workers would never collect. When the United States adopted Social Security in 1935, it set its own retirement age at sixty-five, directly borrowing the framework Bismarck had established, and the number persisted long after life expectancies had shifted the math entirely.
