[3] Ellis began her career acting Off-Broadway and selling radio and television scripts.
[3] In the late 1950s, Ellis later reported to her niece Robin Cohen that she had written and produced a play in Greenwich Village that had a sympathetic portrayal of lesbian relationships.
Literary scholar Yvonne Keller named Ellis among a small group of writers whose work formed the subgenre of "pro-lesbian" pulp fiction; others include Ann Bannon, Sloane Britain, Paula Christian, March Hastings, Marjorie Lee, Claire Morgan, Vin Packer, Randy Salem, Artemis Smith, Tereska Torres, Valerie Taylor, and Shirley Verel.
[6] A fellow Midwood-Tower Publications author and editor, Gilbert Fox, said of Ellis: "Julie was not a “dirty book writer”, didn't belong in our business, too much class.
These books were no longer in the lesbian pulp genre, but more contemporary, historical fiction, suspense, and family sagas.
[12] In 2003, Ellis was a featured guest at the Paperback Collectors convention in New York City, along with another classic lesbian pulp fiction author, Ann Bannon.
[15] In 2020, Robin created and posted to youtube a video memoir called My Life in the Pulps about her discoveries and contact with Ann Bannon, Valerie Taylor and finally her great aunt Julie Ellis.
