WASHINGTON (AP) — The street outside of NASA’s headquarters in Washington, D.C., has been renamed “Hidden Figures Way” to honor the black female mathematicians who helped send humans to the moon.

News outlets report district officials, NASA administrator Jim Bridenstine, Republican Sen. Ted Cruz of Texas and others gathered Wednesday to unveil the new street sign.

“Hidden Figures” author Margot Lee Shetterly and the families of Katherine Johnson, Dorothy Vaughan and Mary Jackson also attended the event. Shetterly’s 2016 book details the struggles of the women as they crunched numbers at the NASA Langley Research Center in Hampton, Virginia, in the pre-computer age.

Cruz in August proposed renaming E Street SW through the Hidden Figures Way Designation Act, which passed in December.
