Grafted Into History is an educational series created by architectural conservator and educator Joseph Humann that explores the building materials, technologies, and craftsmanship that shaped New York City's built environment.

From Hudson River red common brick and Westchester white marble to cast iron facade architecture, terra cotta, steel, Guastavino thin tile vaulted ceilings and reinforced concrete, each episode reveals how the fabric of the city was created—and how it continues to be preserved for future generations.
