Margaret McMillan CH CBE (20 July 1860 – 27 March 1931) was a nursery school pioneer and lobbied for the 1906 Provision of School Meals Act. Working in deprived districts of London, notably Deptford, and Bradford, she agitated for reforms to improve the health of young children, wrote several books on nursery education and pioneered a play-centred approach that has only latterly found wide acceptance.[1]
