Slumming Among the Unemployed: William Wycoff Studies Joblessness in the 1890s
Even before the 1890s depression struck with devastating force in 1893, large numbers of jobless men and women competed in tight labor markets and faced homelessness. One of the best first-hand descriptions of "what it is to look for work and fail to find it" comes from political economist Walter Wycoff's two-volume study of The Workers: An Experiment in Reality, first published in 1899. Wycoff had abandoned his studies at Princeton to seek a more concrete appreciation of social problems. His re

No Way Out: Two New York City Firemen Testify about the 1911 Triangle Shirtwaist Fire

In this brief excerpt from their testimony before the Factory Investigation Commission, New York City Fire Chief Edward F. Croker and Fire Marshall William Beers commented on the safety lapses--the locking of an exit door, the inadequate fire escapes, and the overcrowded factory floor--that led to

Dissatisfied With the Lives They Live: Farm Women Describe Their Work in a 1913 U.S. Department of A
Statistics on women's work in the early 20th century were invariably misleading: most women worked but only a minority were formally in the wage labor force. Nowhere was the discrepancy between the domestic ideal and the reality of women's work lives wider than in rural America. In 1913 the U. S. Department of Agriculture decided to investigate and document the lives of farm woman they discovered a vast reservoir of discontent. The report, reproduced here, was culled from letters responding to a

They channeled the river to create farmland in the desert. They built Pueblo-style buildings. They left no written records. This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.
