with Dr George Johnston, who was noted for advocating pain-relieving medication. He advised her to use chloroform in childbirth and in 1851 Gatty became the first woman in Sheffield to do so. She died at home on 4 October 1873 and was buried in Ecclesfield churchyard. Legacy A marble tablet was installed in the north side of the nave of the Church of St Mary, Ecclesfield, was installed in memory of her. It indicates that it was subscribed by more than a 1,000 children "as a token of gratitude for the many books she wrote for them". There is also a stained glass window in the chancel that was installed in her memory. It includes a representation of her as well as of the Sermon on the Mount and several parables. Gatty amassed a large collection of marine material, gathered by herself and by correspondents in far corners of the British Empire as well as the UK. This was donated to two places by her daughter, Horatia Katherine Francis Eden (née Gatty). Weston Park Museum received part of the collection of seaweed and sponges assembled by both Gatty and her daughter. These were donated in several parts between 1877 and 1909. It comprises 350 items including both folio albums and individual specimens. In April 1907 part of Margaret Gatty’s herbarium was donated by her daughter to the Gatty Marine Laboratory in St Andrews and later incorporated into the St Andrews University Herbarium in the Department of Botany. Starting in 1947 these specimens were partly described by Helen Blackler. More recently the herbarium was moved to the St Andrews Botanic Garden. The laboratory was named after its benefactor Charles Henry Gatty (1836-1903), a distant cousin of Gatty’s husband. A total of 8,825 specimens and 500 plates exist currently at St Andrews, many in their original albums. Several species of seaweed were named after her, including the Australian monospecific genus Gattya pinnella.
