The creation of the modern mutual fund industry is widely credited to pioneering financial innovators in the Netherlands and the United States, with the concept evolving significantly during the 18th and 20th centuries. The earliest recognized precursor to the modern mutual fund was established in the Netherlands by a Dutch merchant and broker named Adriaan van Ketwich in 1774, named "Eendragt Maakt Magt," which was designed to spread investment risk for everyday participants across various international government bonds and loans. Decades later, the concept was introduced to the United States with the establishment of the Massachusetts Investors Trust in 1924, marking the official birth of the open-end mutual fund structure that allowed pooled capital to be professionally managed across diverse public equity portfolios.
