In addition to jointly running Gilbreth, Incorporated, their business and engineering consulting firm, Lillian and Frank wrote numerous publications as sole authors, as well as co-authoring multiple books and more than fifty papers on a variety of scientific topics. However, in their joint publications, Lillian was not always named as a co-author, possibly due to publishers' concerns about naming a female writer. Although her credentials included a doctorate in psychology, she was less frequently credited in their joint publications than her husband, who did not attend college.
