The Midway City Museum is one of the nation's largest museums of natural history. It is particularly noted for its extensive collection of Egyptian artifacts and Medieval weaponry.
One of the museum's earlier curators was Ed Emmet, the brother of Midway City police commissioner George Emmett. When Ed retired, George used his influence to allow Thanagarian police officers Katar and Shayera Hol the opportunity to take his place. Assuming the Anglican names Carter and Shiera Hall, they became the museum's new curators.
One of the Midway City Museum's most famed matrons was the naturalist Mavis Trent. Upon meeting Carter Hall, Mavis became instantly smitten with him and persistently tried to seduce him despite the fact that he was married. Mavis' press agent was Joe Tracy, who was secretly in love with her, and frequently visited the museum on Mavis' behalf.
