Mollie Orshansky developed the original U.S. poverty thresholds in 1963-1964 while working for the Social Security Administration. She defined poverty as a family earning less than three times the cost of a basic food budget, establishing the first standardized measure of poverty in the United States. Her "Mollie's Measure" was influential in launching the War on Poverty under President Lyndon B. Johnson and establishing poverty guidelines still used today.
