The earliest health insurance policies were designed primarily to compensate for income lost while workers were ill. Long absences were a big problem for companies that depended on manual labor, so they often hired doctors to tend to workers. In the 1890s, lumber companies in Tacoma, Washington, paid two enterprising doctors 50 cents a month to care for employees. It was perhaps one of the earliest predecessors to the type of employer-based insurance found in the United States today.
