In the middle half of the nineteenth century, more than one-half of the population of Ireland emigrated to the United States. So did an equal number of Germans. Most of them came because of civil unrest, severe unemployment or almost inconceivable hardships at home. This wave of immigration affected almost every city and almost every person in America. From 1820 to 1870, over seven and a half million immigrants came to the United States — more than the entire population of the country in 1810. Nearly all of them came from northern and western Europe — about a third from Ireland and almost a third from Germany. Burgeoning companies were able to absorb all that wanted to work. Immigrants built canals and constructed railroads. They became involved in almost every labor-intensive endeavor in the country. Much of the country was built on their backs.

It started with a 10% pay cut. When leaders of the Baltimore and Ohio Railroad Company ordered this second reduction in less than eight months, railroad workers in Martinsburg, West Virginia decided they had had enough. On July 16, 1877, workers in that town drove all the engines into the roundhouse and boldly declared that no train would leave until the owners restored their pay. The local townspeople gathered at the railyard to show their support for the strikers. A great showdown was on.

The Age of Industry brought tremendous change to America. Perhaps the single greatest impact of industrialization on the growing nation was urbanization. Thomas Jefferson had once idealized America as a land of small, independent farmers who became educated enough to participate in a republic. That notion was forever a part of history.

Workers rarely found a helping hand in the White House. President Hayes ordered the army to break the Great Railroad Strike of 1877. President Cleveland ordered federal troops to disrupt the Pullman Strike of 1894. Governors and mayors used the National Guard and police to confront workers on strike. When Pennsylvania coal miners went on strike in 1902, there was no reason to believe anything had changed. But this time things were different. Teddy Roosevelt was in the White House.

The large population, generous natural resources, advanced infrastructure, and solid capital base were all just potential. Centralization and mobilization were necessary to jump-start this unwieldy machine. Within a week of Pearl Harbor, Congress passed the War Powers Act, granting wide authority to the President to conduct the war effort. Throughout the war hundreds more alphabet agencies were created to manage the American homefront.

The growth of tobacco, rice, and indigo and the plantation economy created a tremendous need for labor in Southern English America. Without the aid of modern machinery, human sweat and blood was necessary for the planting, cultivation, and harvesting of these cash crops. While slaves existed in the English colonies throughout the 1600s, indentured servitude was the method of choice employed by many planters before the 1680s. This system provided incentives for both the master and servant to increase the working population of the Chesapeake colonies.

The Lawrence Textile Strike was a public protest mainly of immigrant workers from several countries, including Austria, Belgium, Cuba, Canada, France, England, Germany, Greece, Ireland, Italy, Lithuania, Netherlands, Norway, Poland, Portugal, Russia, Scotland, Spain, Syria, and Turkey. According to the 1910 census, 65% of mill workers (many of whom eventually struck) lived in the United States for less than 10 years; 47% for less than five years. Prompted by a wage cut, the walkout spread quickly from mill to mill across the city. Strikers defied the assumptions of conservative trade unions within the American Federation of Labor that immigrant, largely female and ethnically diverse workers could not be organized. The Lawrence strike is referred to as the “Bread and Roses” strike and “The Strike for Three Loaves." The first known source to do so was a 1916 labor anthology, The Cry for Justice: An Anthology of the Literature of Social Protest by Upton Sinclair. Prior to that, the slogan, used as the title of a 1911 poem by James Oppenheim, had been attributed to ‘Chicago Women Trade Unionists.’ It has also been attributed to socialist union organizer Rose Schneiderman. James Oppenheim claimed his seeing women strikers in Lawrence carrying a banner proclaiming “We Want Bread and Roses Too” inspired the poem, “Bread and Roses.” The poem, however, was written and published in 1911 prior to the strike. Later the poem was set to music by Caroline Kohlsaat and then by Mimi Farina. The song and slogan are now important parts of the labor movement and women’s movement worldwide. This exhibition was made in collaboration with the Lawrence History Center and the University of Massachusetts Lowell History Department.

This collection uses primary sources to explore the Bracero Program. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States.

Amidst tensions over European political and territorial boundaries, the assassination of Archduke Franz Ferdinand by a Serbian terrorist in 1914 derailed peace in the western world by sparking World War I—one of the highest-casualty conflicts in modern times. While European nations quickly engaged, the United States immediately declared neutrality. By 1917, however, remaining neutral was no longer an option. The Great War would bring the United States out of isolationism and onto the world stage. It would also change life on the American home front forever. A centralized government took control of American life in an unprecedented fashion by instating a mandatory military draft, controlling industries, initiating food and ration restrictions, and launching elaborate campaigns to encourage patriotism. One of the most important, if temporary, changes brought by the war at home came from the stifled flow of labor, as men were pulled away by the draft and immigration slowed. The need for American labor provided second-class citizens, such as women and African Americans, a brief opportunity for better jobs. This glimpse would help foment in them a desire for more and equal opportunities after they were pulled away once more at war’s end. This exhibition was created as part of the DPLA’s Public Library Partnerships Project by collaborators from Digital Commonwealth. Exhibition organizer: Anna Fahey-Flynn.

Students learn about the major factors that comprise the design and construction cost of a modern bridge. Before a bridge design is completed, engineers provide overall cost estimates for construction of the bridge. Students learn about the components that go into estimating the total cost, including expenses for site investigation, design, materials, equipment, labor and construction oversight, as well as the trade-off between a design and its cost.

Students discuss several human reproductive technologies available today pregnancy ultrasound, amniocentesis, in-vitro fertilization and labor anesthetics. They learn how each technology works, and that these are ways engineers have worked to improve the health of expecting mothers and babies.

This collection uses primary sources to explore women's work on the home front during World War II. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Student teams learn about and devise technical presentations on four reproductive technology topics pregnancy ultrasound, amniocentesis, in-vitro fertilization or labor anesthetics. Each team acts as a panel of engineers asked to make a presentation to a group of students unfamiliar with the reproductive technology. Each group incorporates non-lecture elements into its presentation for greater effectiveness. As students learn about the technologies, by creating a presentation and listening to other groups' presentations, they also learn more about the valuable skill of technical communications.
