Flatiron History

Discover Flatiron: Mohawk Ironworkers Give Rise to NYC Skyscrapers

November is Native American Heritage Month. In honor of contributions made by Mohawk, or Kanien ľkehá:ka, ironworkers who helped construct New York City’s iconic skyline, the Flatiron Partnership highlights the role of the group in the area’s building boom era of the 20th century.

Mohawks are members of the Haudenosaunee, commonly known as the Iroquois Confederacy, which also includes the Oneida, Onondaga, Cayuga, Seneca, and Tuscarora nations. During the turn of the 20th century, construction job opportunities began to flourish in North America, and soon Mohawks from Canada and upstate New York would seek employment as ironworkers. “New York was by far the largest city in the United States in 1900, and the richest,” wrote Jim Rasenberger in High Steel: The Daring Men Who Built the World’s Greatest Skyline. In a number of U.S. cities, explained Rasenberger, “skyscrapers had moved out of their infancy and into their rowdy adolescence, and New York was where they came to spend it.” 

According to the website for the National Museum of the American Indian, “Haudenosaunee men began ‘walking iron’ in 1886, when they were hired to work on a bridge being built over the St. Lawrence River. Upon completion of the bridge, Haudenosaunee men began their tradition of ‘booming out.’” The term characterizes the urban migration by ironworkers who left their Native communities to find employment elsewhere. Reportedly, Mohawk ironworkers began working in regions as far south as New York City in 1901. “The men were thrilled to be working away from home and seeing new sights,” said Lynn Beauvais, a Kahnawake resident and grandmother from a fourth-generation ironworker family (via “They were a band of brothers.”

Mohawk ironworkers may have been members of construction crews who built the popular steel-framed properties during this period, including the Flatiron Building and Metropolitan Life Insurance Company’s Clock Tower. Located at the crossroad of 23rd Street, Broadway, and Fifth Avenue, the Flatiron Building was completed in 1902. The Clock Tower at Madison Avenue between 23rd and 24th Streets was finished in 1909. “Performing dangerous work several hundred, if not several thousand, feet up in the air requires amazing concentration, courage, and grit—the very qualities the Mohawks would ascribe to their ancestors throughout their long history,” wrote David Weitzman in Skywalkers: Mohawk Ironworkers Build the City.

By the early 1920s, according to High Steel author Rasenberger, “Mohawks were regularly crossing the border to work on bridges and buildings up and down the Eastern Seaboard, traveling together in tight four-man gangs, communicating on the steel in Mohawk, boarding together wherever they could find inexpensive housing.” In 1925, however, a Mohawk ironworker was arrested for illegal immigration in Philadelphia. The case resulted in a landmark federal court decision in 1927. Citing the Jay Treaty, noted Rasenberger in High Steel, “the judge ruled that Mohawks, whose land had once overlapped parts of both countries, were entitled to pass freely over the border from Canada into the United States.” When they arrived in New York City, many Mohawk ironworkers and their families reportedly resided in Brooklyn’s North Gowanus section, now known as Boerum Hill, around Atlantic and Fourth Avenues.

Some of the notable skyscrapers Mohawk ironworkers would help produce include the Empire State Building, completed between 1930 and 1931, the Chrysler Building in 1930, and the launched construction of the World Trade Center towers during the late 1960s. When the 9/11 terrorist attacks occurred, Mohawk ironworkers helped with the recovery, as well as the construction of the new One World Trade Center, or Freedom Tower, which opened in 2014. “For many Haudenosaunee communities, ironworking has become a tradition,” notes the National Museum of the American Indian’s website about the ironworkers who are also union members of the Kahnawake locals 40 and 361. “They learn from and with people they trust. Today they continue to work on high steel, carrying the Haudenosaunee reputation for skill, bravery, and pride into the twenty-first century.”

Flatiron Faces

Flatiron Faces: Christina Cho Yoo & Ming Thompson, Co-Founders of Atelier Cho Thompson

Meet Christina Cho Yoo and Ming Thompson, Co-Founders of Atelier Cho Thompson, this year’s winner of the Flatiron Public Plaza Holiday Design Competition presented by the Flatiron/23rd Street Partnership and Van Alen Institute.

Atelier Cho Thompson’s art installation will appear on the Flatiron North Plaza at the intersection of Broadway, Fifth Avenue, and 23rd Street as the centerpiece of the Partnership’s “23 Days of Flatiron Cheer” program and will be on display from November 22rd through January 2nd. The design's interactive story wall, made of backlit papers hung on a grid, invites visitors to share responses to the prompt: “I dream of a world where together we can....” The resulting narratives will become a patchwork of voices documenting this challenging yet hopeful moment.

1. Congratulations on being selected as this year’s winner of the Flatiron Public Plaza Holiday Design Competition for your interactive concept titled Interwoven. What was your reaction upon hearing the news?

CC: We were surprised and excited. When we learned about the other invitees and their designs, we felt even more honored to be considered alongside such amazing firms doing such innovative, meaningful work that not only expanded the scope of what architects do but also who we design for.

MT: This year’s group of finalists all share an interest in architecture’s potential to have social impact and create hopeful shared experiences for our communities.

Interwoven on display Nov 22 - Jan 1

2. Interwoven will appear on the Flatiron North Plaza at the intersection of Broadway, Fifth Avenue, and 23rd Street. You’ve indicated that your installation “offers a platform for stories and dreams of our future.” Tell us more and the inspiration behind your design.

MT: We began with the idea of interweaving; after almost two years, we are all returning to the public spaces of our cities, where our paths and lives will intersect. Our earliest sketches showed criss-crossing arches inspired by agricultural structures and garden trellises. Drawing from the intersecting angles of the site, we explored how we could interweave parabolic arches to create a robust structure and welcoming, dynamic form.

In all of our work, we try to build community around design. We aim to use design to address community issues, like in our Design Brigade program, but we also aim to directly engage people in creating shared design solutions and vision for the future. From the beginning, we wanted to have a story wall component, where people could contribute hopes and ideas to a collage. We were lucky to connect with Youth Fellows from the People’s Bus NYC project to create a prompt for those stories.

CC: I’ve always loved the idea of America as a tapestry of different people because that metaphor implies that all the elements in the cloth retain their identity and need to bend a little to weave together. For better or worse, this pandemic has connected people across the world through a shared experience unlike anything most of us have experienced in our lifetimes. Through the sadness and challenges that we have faced, our installation looks for the silver linings and urges us forward to a more hopeful future as we realize how much we craved connecting with each other in public space.

3. The installation is outfitted with interactive components, including archways activated by color-coded light and musical sensors, a hammock, and benches. What do you hope the public’s takeaway will be when experiencing your installation?

MT: Interwoven reacts to human input, and that reinforces the idea that all of us should have the power and the agency to shape our built environment. The architecture of our city isn’t stagnant; it’s alive, ever-changing, and shaped by the actions of all who wish to have their voices heard. In the words of Elizabeth Alexander in the National Monument Audit, “Our built environment is in motion; it always has been in motion.” From our streets to our neighborhoods to our cities, we can all play a role in shaping that motion.

CC: The sensor-activated lighting and musical effects reinforce the idea that people connecting and working together can produce unexpected, beautiful results. We invited musicians to come up with original compositions or to play pieces that responded to the prompt: We possess a fundamental desire to connect with each other through shared experiences and to celebrate our differences. Interwoven offers a platform for stories and dreams of our future. We've faced isolation and we've seen political, socioeconomic, ethnic strife of all sorts. In light of these isolating, trying times, we're wanting to convey a message of hope, as we've realized how interconnected we are and how much we crave connection with each other like never before.

4. You’re the co-founders of Atelier Cho Thompson (ACT), an award-winning multidisciplinary design and concept company with offices in San Francisco and New Haven. ACT is also certified as a Women-Owned San Francisco Local Business Enterprise and is a member of the Female Founders Collective. Briefly describe your company, your roles, and what led to your business partnership in 2014?

MT: Christina and I had a dream of creating an architecture firm that went beyond buildings. We have sought to find and build a more humane vision of architecture, one built around the human body and around building community around design.

CC: Ming worked in museums and had a graphic design business prior to architecture school. I was a structural engineer who loved gardening, making furniture, and exhibition design. We believed that architecture had to serve both those with and without a lot of money and resources. We believed design could give agency and a voice to people who typically did not feel like that had those things. Ming and I both yearned for a broader definition of architecture that we could not find in a firm, so we created it.

5. You were classmates at Harvard’s Graduate School of Design. What led you to Cambridge, and later, your pursuit of architecture?

MT: I’m from a small town in Appalachia, and I grew up in my parents’ wildly creative restaurant in a dairy barn. For my whole life I have simply loved making things, and it was only when a college friend towed me to an architecture class that I discovered that I could make a whole career, a whole life out of that love of making. Since that first moment, I have loved the challenges of architecture, of solving problems, of taking an idea from concept to execution, and of working within and finding opportunities in constraints. We just happened to be assigned desks together in our first year of grad school. After long nights of models and drawings, our friendship was born.

CC: I worked as a structural engineer at Arup prior to architecture school. Working for many years on the California Academy of Sciences by Renzo Piano eventually pushed me over to the other side, i.e., architecture. I loved how the architect could be involved in overseeing everything from the exhibition design to designing the entire building itself, managing many different consultants towards a common goal, teaching people about sustainability through the building design, and surmounting technical challenges of designing a rainforest dome and aquarium in one of the most seismic areas in the world. The possibilities are vast as an architect, and I love that we can be visionaries, pushing the boundaries of what the built environment can be and who it is built for.

6. Speaking of architectural style, Flatiron/NoMad is known for its distinctively-designed properties and public spaces. What’s your favorite building or architectural element here in the neighborhood?

MT: I love the view from the Flatiron Plaza––the Chrysler Building in the distance, the ornamented façade of the Flatiron Building, the Metropolitan Life Clock Tower, the new glass towers. It’s the layering of history made visible.

7. What do you like most about Flatiron/NoMad? When you’re in the neighborhood, how do you like to spend your time?

CC: I live in San Francisco, so it’s been a while since I’ve been in the neighborhood, but I do want to check out Cote Korean Steakhouse/Undercote, abcV, (a vegetarian place by Jean-Georges who never disappoints), and Sugarfish, melt-in-your-mouth sushi I first had in LA. When I’m there soon, I’ll make a requisite visit to Shake Shack and probably pick up a LEGO set for my kids at the LEGO store. For work, I’ll probably stop by ABC Carpet & Home. Gotta get a little something for my stomach, something for my kids, and then something for work.

8. Finally, choose three words to describe the Flatiron District.

MT: Vibrant. Layered. Interwoven!

CC: Active. Gastronomic. Varied.
