Large technological systems can be vulnerable to manipulation, perhaps especially when they are centralized, monopolistic, and complacent. That was the situation in American telecommunications in the early 1960s when a generation of hackers developed techniques to manipulate the Bell telephone system to their advantage, a practice known as phone phreaking.

In his dissertation research, Jacob Bruggeman, PhD candidate at the Johns Hopkins University, digs into the technology and politics of hackers, tracing their trajectory from anti-establishment actors on the fringes of technological systems, to positions of influence and control over the very same systems. In parallel to these developments in the hacker community, major organizations, both public and private, adopted new positions and policies designed to secure the system.

In support of his research, Bruggeman received funding from the Center for the History of Business, Technology, and Society at the Hagley Museum and Library. For more information, and more Hagley History Hangouts, please visit us online at hagley.org

What is jazz and when did it begin? Music scholars do not agree. Taking an archival perspective, however, clarifies the dilemma and allows us to see jazz where people at the time performed, recorded, consumed, and discussed what they thought of as jazz music. The emergence of jazz as an economic force, and a defining cultural aspect of an era, were tightly bound up in the prevailing system of racism, segregation, and inequality in the early twentieth-century United States.

In her latest book project, Stephanie Doktor, assistant professor of Music Studies at Temple University, explores the racial context within which the jazz recording industry developed, and the indelible mark left by the systemic racism of the period upon the music industry to the present day. Using the Victor-RCA records held in the Hagley Library, Dr. Doktor reveals how race, class, and gender mutually shaped the political economy of early jazz.

Tracing the circulation of ideas can cast light on patterns of interaction between various people and institutions in the past. During the mid-late twentieth century, a circuit of ideas linked business culture, industrial designers, academia, and related professional organizations. The movement of values, techniques, and perspectives between these distinct but interpenetrative spaces illuminates how they related to one another in historical context.

In her latest research Penelope Dean, professor of architecture at the University of Illinois at Chicago, uncovers this movement of ideas and uses it to bring business and design histories into conversation. Using numerous collections held in the Hagley Library, including the Raymond Loewy and Ernest Dichter collections, Dean identifies the spread of ideas between business and design, and the development of a shared language capable of communicating complex concepts across professional groups.

The positive image cannot exist without the negative, and the relationship between the two reveals the fundamental nature of the image as fungible, media as a process, and truth value as a matter of interpretation. Scholarship and conservation therefore have a profound responsibility to collect, preserve, and interpret media negatives for what they reveal about the relationship between positive images and the truth.

In her latest project, Dr. Stefka Hristova, associate professor at Michigan Technological University, theorizes the relationship between media negatives, their positive counterparts, and the truth value accessible through a careful study of both. Using the collections held in the Hagley Library, Hristova demonstrates that a photographic image cannot be understood without reference to its negative. Likewise, and with profound implications for our present moment, the images and other media generated algorithmically cannot be properly judged or interpreted without an understanding of their negatives, the data used as the means of generating the final image.

In this episode of Hagley History Hangout Roger Horowitz interviews Margot Canaday about her remarkable book Queer Career: Sexuality and Work in Modern America that received the received 2024 Hagley Prize for the best book in business history that year.

Canaday’s Queer Career’s rincipal focus is on the private sector, business enterprises large and small, and traces the opportunities, obstacles, and accomplishments of LGBT+ people as they sought to make a living from the 1950s through today. She emphasizes that as federal and many state agencies routinely refused to hire LGBT+ people, their most important sources of employment was in the private sector. Still facing pressures to keep their sexuality hidden in their jobs, their precarity lead them to accept lesser positions and pay than they might otherwise would have qualified for. Once stablished, they nonetheless made great strides in economic opportunity over these decades in white collar and blue collar jobs, and by creating their own firms.

Her analysis is leavened by the personal stories of the many remarkable men and women who fill the pages of Queer Career. Canaday plants her feet firmly in business history by tracing firms ranging from “movement” enterprises such as Olivia Records and Diana Press that were vehicles for empowerment to large corporations Bell Labs and Lotus, where organizations of LGBT+ employees stepped out of the closet and secured health benefits for domestic partners.

With sources ranging from over 100 oral histories, to legal proceedings, government records, and materials from private collections, she tells a story that has not been told before, in many areas not even touched.

Excessive heat has presented a problem for public health officials in New York City since the mid-nineteenth century building boom that covered the island of Manhattan in bricks, concrete, and other heat-storing materials. Prior to that, however, Americans had noticed that cities were warmer than their surrounding countryside as early as the 1790s. The phenomenon now known as the “urban heat island” has shaped the bodily experiences and collective destinies of millions.

In her latest research, Dr. Kara Schlichting, associate professor at the City University of New York, uncovers the complex relationship between the evolving built environment of the city, the macro-climatic conditions prevailing globally, and the socially-differentiated lived experiences of heat had by city residents. By digging into Hagley collections, including trade catalogs and the Willis Carrier collection, Schlichting is able to tell a history that links multiple scales of time and space, an act of scholarly imagination that allows us to assess the technological and political systems that shape the climate we all must live with.

In support of her research, Dr. Schlichting received finding from the Center for the History of Business, Technology, and Society at the Hagley Museum and Library. For more information, and more Hagley History Hangouts, visit us online at hagley.org.

The political meaning of industry depends upon its context. Following the Second World War, Native American tribal governments engaged in a program of industrial development meant to secure the political self-determination of their nations. Initially concerned with attracting capital investment to reservation communities, by the 1970s native governments had moved on to become investors in wholly owned tribal enterprises.

In his dissertation research, Sam Schirvar, PhD candidate at the University of Pennsylvania uncovers a story that is both surprising and revealing of deeper patterns in American history. While outsiders saw industrial development as a means to efface native communities and tribal governments, tribal leaders themselves saw it as a means to self-determination. While the wider American economy was moving toward privatization of enterprise, Native Americans were creating publicly owned industries. Industry can mean different things to different people at different times.

In support of his research Schirvar received the Louis Galambos National Fellowship in Business and Politics from the Center for the History of Business, Technology, and Society at the Hagley Museum and Library.

Ben Spohn interviews Mark Aldrich about his 2018 book, Back on Track American Railroad Accidents and Safety 1965-2015. This period marked a decline in safe operating on American railroads through the 1970s which were followed by a period of increased safety and profitability for American railroads. Aldrich makes the case that the joint factors of economic deregulation through the Staggers Act and the federalization of railroad safety via the Federal Railroad Administration (FRA) drew attention to safety issues on the railroad like poor track condition, unsafe grade crossings, or engineer fatigue and left railroads with not only incentives to become safer, but enough money in their coffers to adequately shore up these safety concerns.

Mark Aldrich is the Marilyn Carlson Nelson Professor of Economics emeritus at Smith College. Back on Track American Railroad Accidents and Safety 1965-2015 is a sequel to Aldrich’s earlier book on railroad safety, Death Rode the Rails: American Railroad Accidents and Safety, 1828-1965. As part of his research for Back on Track Aldrich visited the archives at Hagley. His upcoming book on energy transitions: The Rise and Fall of King Coal American Energy Transitions in an Age of Markets 1800-1940 will be out in early 2025.

In support of his research Aldrich received funding from the Center for the History of Business, Technology, and Society at the Hagley Museum and Library. For more information and more Hagley History Hangouts visit us online at hagley.org.

The DuPont firm was a leader in workplace and community safety communications during the twentieth century. This had been baked into the company culture from the first, as gunpowder manufacturing made essential. What changed over time were the techniques and media of communication, and the intended audience targeted by the company’s messaging.

In her latest research, Madison Krall, assistant professor of communication studies at Seton Hall University, explores the wealth of health and safety materials generated by the DuPont company during the twentieth century. From posters to motion pictures, the firm deployed a wide array of media to promote safety in the workplace and beyond. DuPont wished to convince the public that its products were safe, and to convince employees and community members that safety was their responsibility.

In support of her work Dr. Krall received funding from the Center for the History of Business, Technology, and Society at the Hagley Museum and Library. For more Hagley History Hangouts, and more information visit hagley.org.

Scholars often think and write about business diplomacy as something that happens between firms and national governments. But the historical pattern is more complex than that, with contacts between businesses forming a significant portion of the international circuit of communication about business and economic matters.

As part of his doctoral research, Grigorios Antoniou, PhD candidate at the National and Kapodistrian University of Athens, is exploring the significance of international industrial conferences to the development of a global network that linked high-level business leaders from across boundaries between industries, sectors, and countries. Using collections held in the Hagley Library, including the National Industrial Conference Board and trade catalog collections, Antoniou uncovers a milieu in which elites met to mingle, cut deals, and burnish their status.
