Lavinia Lloyd Dock (February 26, 1858 – April 17, 1956) was a nurse, feminist, author, pioneer in nursing education and social activist. Dock was an assistant superintendent at Johns Hopkins School of Nursing under Isabel Hampton Robb. She founded what would become the National League for Nursing with Robb and Mary Adelaide Nutting. Dock was a contributing editor to the American Journal of Nursing and authored several books, including a four-volume history of nursing (with M. Adelaide Nutting as co-author) and Materia Medica for Nurses, the nurse's standard manual of drugs for many years. In her later life, she also campaigned for social reform, particularly women's rights. Early life Lavinia Dock was born one of six children in Harrisburg, Pennsylvania on February 26, 1858.
