" In his early career, Dodds was frequently aided by his girlfriend, Dian Belmont, who is aware of his dual identity. Unlike many superhero love interests, Belmont was often, though not always, portrayed as an equal partner of the Sandman, rather than a damsel in distress. Later stories would reveal that the two remained together for the duration of their lives, though they never married."
"The Sandman was one of the original members of the Justice Society of America when that superhero team was introduced in All Star Comics #3, published by All-American Comics, one of the companies that would merge to form DC."
