Laurence Schexnayder was Sally Jupiter's manager, and later, her first husband.
Laurence and Sally were known each in Europe. Once they were broke in Warsaw and Larry found a job for her at the Moritz. There, he heard a Prince commenting that Sally is the most beautiful woman in Europe.
Larry saw the costumed adventurers as a social fad on which he could cash in. He staged criminal assaults with retired actors, hindered by the Silk Spectre. The police were also in the trick, and he would complain to the cops that they were asking for more each time.
Nelson Gardner contacted Larry inviting him to consider a joint effort of all the costumed adventurers. He offered them his "base", in exchange for Sally's cooperation and Larry's publicity and management talents. This led to the creation of the Minutemen.
During the Minutemen era Schexnayder worked as their manager, taking track of how often often the group's exploits made the newspapers, how popular the radio shows were, booking publicity stills, and even make arrangements for those of the team who needed help with living expenses, like young Eddie Blake. Alway caring about the team's public image, he needed to cover Hooded Justice's homosexuality by arranging Sally to "beard" him.
He also convinced Jupiter not to press charges against the Comedian, who attempted to rape her following a photo shoot of the group in 1940. It's possible this incident made him realize who Laurie's father really was.
Hollis Mason considered Schexnayder to be greedy and inhuman sometimes, caring mostly for attention and cover-ups. In his book, Under the Hood, Mason describes Schexnayder as "tireless and shrewd." Schexnayder had supposedly understood that costumed adventuring was becoming increasingly unpopular.
Shortly after Sally's retirement, the two married in 1947. The nine-year marriage was tumultuous, especially after Jupiter had her only child, Laurel Jane, in 1949. The two divorced sometime in 1956. Laurie's father, whom she believed to be Hooded Justice, was in actuality the Comedian, with whom Jupiter had an affair while married. Knowing that Jupiter had an affair during their marriage, Schexnayder became despondent; Laurie, while speaking with Jon Osterman on Mars, recounts an argument between Sally and Laurence where Sally angrily tells her husband that the man she'd had the affair with was more attentive to her own needs. It is not revealed whether Schexnayder knew the identity of the man.
In 1962 Mason sent him his draft of Under the Hood, but Laurence was not enthusiastic about it, believing that it was far too revealing. He took the train to New York and the two met in Stilton, trying to convince him against it. Mason accused him for caring only for the Minutemen "brand name" and his plans to gain from it.
