1911 – First Workers' Compensation laws in Illinois to protect against lead poisoning and other workplace hazards.

* Hamilton authored the "Illinois Survey," a report that documented its findings of industrial processes that exposed workers to lead poisoning and other illnesses. * She discovered over seventy industrial processes through which workers became exposed to lead poisoning. * She also uncovered occupations, such as polishing cut glass and wrapping cigars in "tinfoil," that exhibited increased exposure to lead poisoning. * The commission's efforts resulted in the passage of the first workers' compensation laws in Illinois in 1911, in Indiana in 1915, and occupational disease laws in other states, requiring employers to take safety precautions to protect workers.
