“You might not know about Regina Anderson, but you’ve probably heard of many of her friends. On a typical day in 1923 or 1924, Anderson might leave her desk at the 135th Street Branch of the New York Public Library and drop a letter to W.E.B. Du Bois in the mailbox. She may go home to her apartment on St. Nicholas Avenue to check up on her couchsurfer, Zora Neale Hurston. Or she might hit the town with Countee Cullen, and then finish out the night cooking bacon and eggs for Langston Hughes.”
