The popular narratives about race have often been tied to differences in physical health and intelligence, as Molina noted after an audience member asked about the role of eugenics in shaping these stories. Lee pointed to the Ku Klux Klan and its reliance on myths of physical and mental disparities between races as a method of enforcing racial segregation and white supremacy, to maintainan “America for Americans.”

In another context, purported differences in physical constitution encouraged agricultural and railroad construction employers to hire Mexicans. Molina explained that people in the United States believed Mexicans to be biologically different: their bodies, it was said, could withstand 110-degree Fahrenheit heat better and produce more work in the fields. But when the Great Depression rolled around, those same workers became economic scapegoats, and characterized as immigrants who were taking jobs away from native-born Americans. During this period, racist notions created the medical myth that portrayed Mexican workers as more susceptible to diseases like tuberculosis and led to charges that they would burden the nation’s healthcare system.

“It doesn't begin with ethnic and racial minorities,” Gonzalves emphasized. “If we go back to the 1790 Naturalization Act, we have to think about how that was a law that equated citizenship with free white persons of good moral character. . . we have to think about who was really identifying and obsessed with identities. It's clearly the founders themselves. . . . Of course it's going to be an obsession, because [America was founded] on stolen land and everything follows from that. So we are following in the great tradition of America, which is to be obsessed with these questions of identity.”

The museum's curators are collecting items that document the Covid-19 pandemic in the U.S., and are asking the public to help decide what objects or images will represent this time to future generations. “It's so important to be documenting the impact of Covid especially on immigrant and refugee communities,” Lee said, noting that these populations of people are disproportionately working in occupations and industries that put them at greater health and economic risk. “As Dr. Molina pointed out, they are essential workers, but they are not treated as essential. . . . And we need to be collecting their stories.”
