In 1905, she started work at Yerkes Observatory, as assistant and computer for her uncle, the astronomer Edward Emerson Barnard (1857–1923), who was also professor of astronomy at the University of Chicago, and the discoverer of Barnard's star.
In 1923, when Barnard died, she became curator of the Yerkes photographic plate collection and a high-level assistant, until her retirement in 1946.
Barnard’s work A Photographic Atlas of Selected Regions of the Milky Way was completed after his death in 1923 by Edwin B. Frost, director of the Yerkes Observatory, and Calvert, and published in two volumes in 1927. Only 700 copies were printed, making the original edition a collector's item. The Astronomy Compendium calls it a "seminal work".
She died in Nashville in 1974.
