Lamb, Mary, 1764-1847 (Library of Congress Name Authority)— Sister of the author Charles Lamb, Mary Lamb collaborated with her brother on Tales from Shakespeare (1807) as well as some other works for children. After Charles left school, he and Mary resided in their family home until 1796. At that point, exhausted from the strain of caring for aged parents, Mary stabbed and killed their mother and was institutionalized for insanity. Eventually released to Charles's care, she experienced periodic recurrences of instability, several requiring temporary rehospitalization. Her essay "On Needleworking" appeared in the British Lady's Magazine in April 1815. Lamb argued for the professionalization of needlework to provide a respectable and reliable source of income for women thus employed, thereby enabling them to enjoy greater equality with men.
